    Bright but unwieldy.....Russian DIY bike light. Runs from e-bike pack. Glare? Yeah, there's glare. I'm sharing this for humor, mostly. But also, it shows the result of shorting a 98 cell 18650 pack, like many of us use. This is why we say don't short your pack! This guy simply harnessed that power, for light. He'll probably get cataracts, if he uses it too much, though.

    It's awesome, though.

    Fabrication is fun! Build something today. Show someone. Let them help. Inspire and share. Spread the desire.


      I have a DIY set up for commuting. At basics its 2 usb lights, 2 battery packs, a head lamp and a bunch of red flashers. I don't want to get hit from a lack of not being seen.

      In Detail with all the links (sorry I cant post links or the forum sees me as puting up spam even though they arent affiliates or anything of the such just basic amazon links) here goes:

      This was my first setup and is very basic and multipurpose, just like me I think this is pefect set up for a beginner. a light to see with and a light to be seen with.

      I'm going to start with the headlamp because that was actually my first bike light. Of course it works as a headlamp and you can ride with it that way. But if you remove the head strap and use a Ranger band ( a rubber band made from a bike inner tube ) you can mount it right on your stem and the adjustments on the light itself lets you fine tune so you get the light right where you need it. I still carry it with the ranger bands in a case so it could be used as that if my other lights failed. I might add its very handy to have a headlamp if your trying to do a repair or make camp on the side of a trail in heavy shade or come dark time. I use a Princeton Tec Vizz I love this light it uses 3 AAA batteries and has a redlight feature so you dont blind everyone and it has a bright ass light so you can blind people if you choose. if you shop around you can find this headlamp for under $30 but it reatails for $40

      Add to this a Planet Bikes Grateful Red light and you have a good set up both use AAA batteries so I carry a 6 pack of AAA rechargeables with a USB charger. Alkalines in my opinion cant be beat for length of run time in lights but that can add up quickly. I just make sure the recahargeables are topped off before I head out and you get maybe 50% runtime vs Alkalines and if need be the spares would allow me to change out the headlamp twice and the rear light 3 times. The Planet Bikes Grateful Red sells for about $19

      I later added some marker lights that use the CR2032 Coin Cell batteries. I got 2 sets of the Planet Bikes Blinky Safety Bike Light Sets they sell for under $15 each set which include one front white blinky light and one rear blinky light. I currenty have the white front ones mounted on each side of my front basket and the rear ones on each side of my cargo trailer. Ive previously had the front ones mounted each side of my front fork and the rears each side of my chain stay. the planet bike lights come with multiple mounting options and can even just be clipped on a loop of fabric.

      I ran that set up for a long time. Then I added a BlackBurn Outpost Fat Bike Rack and zip tied an 80s black coca cola tray to it and then added 2 more of the Grateful Red lights on the back of it and a Melian X5 witht the lane lasers sells for about $35 this light has a lot of features including an automatic stop light, remote blinkers and hazards and did I mention it has lasers lol. The remote uses a CR2032 and the light unit is usb rechargeable.

      Then I decided to upgrade my front lights and retire my headlamp to...well headlamp duty and back up headlight.

      One of these would probably be adequate but seeing how they were so inexpensive I thought why not get 2. I added 2 Securitylng USB Waterproof 1800 lumen 3 mode lights they sell for under $14 each now and I paid under $10 when I bought them. I will say I dont like the rubber mount it slides around to much. So I got a Lamphus 2pc off road led light bar .75/1/1.25 horizontal bar clamp mounting kit it sold for under $10. The securitylng lights are only held to their metal bases by a philips screw. I filled the whole under the light where the cord came out with hot glue and used a longer screw to tightent them to the Lamphus mounts. they are now rock solid and not going anywhere. I set one light angled at a very slight angle high and one at a very slight angle low. low and high beams and if you need a lot of light run both 1800 lumens times too. I wouldnt run the high in town or with on coming traffic its brighter than most automotive headlights. I live on a rural back road and do some trail riding so it will really light up a space if need be. and they have a strobe function if you have an emergency and need to signal help.

      To power these I bought 2 Anker PowerCore 20100mah battery packs. these sell for about $50 each. I bought 2 well I was thinking for a back up. I can actually run both lights off one pack. That was truly my original intent. However I severly under estimated the usefulness of these packs. You can charge anything that has a usb cord with these. I recently had a storm that knocked out my power and I used one of these packs to watch Youtube for 3 days on my galaxy s5 and I only discharged it half way. To me thats impressive. When I say I was watching Youtbe I mean it was running most of the time there were no lights and if I wasnt I was on face book maybe 8 hours of sleep in 3 days. I was quite impressed. If these packs have a downfall its that they take a long time to fully charge Id say about 8 - 12 hours. But in my opinion they are well worth it. They do have rapid charge packs but they are quite a bit more in price. I have 2 so if I discharge one I can charge the other while using the 2nd. Thes are also useful for recharging light or those AAA batteries if need be.

      I did mention a Cargo trailer. I use an Aosom II which currently sells for $116 I will say I did not pay that I bought mine for $85 just watching the price on amazon. For $85 dollars I dont think you could beat this trailer unless you got one for free. Its typical china construction but I used some read antisieze axle grease and lubed up all the moving metal parts and the axles. Cheap insurance to do a litlle maintenance. I added the Planet Bike Rear Blinky lights to the side wheel guards and mounted 2 more Planet Bike Grateful Reds to the rear of the trailer. I got a rear axle from the Robert Project $75 so I could easily mount my trailer to my bike. I really like the whole set up.

      Sorry for being so wordy but I like to be thurough. I know when Im looking for information on something I like as much detail as possible and still often ask questions after. Hope this helps someone. Of course if yall have any questions or suggestions offer em up. Always looking ot improve my setup.


        Nightrider finally makes a city light. 500 lumens. Since I only use the low setting on my 650, and 750 it should be OK. It has a side light function that their off road lights don't have. In stead of a separate mout it has a built in strap, so it can move from bike to bike. The lens is a sort of beehive pattern. It's different from their off road lights where the pattern was in the reflector. Maybe less glare fro oncoming traffic.
        I found something else. A company called Rydesafe makes reflective decal kits in many colors including black. They have some that do both sides of rims, and even chain links.


          I've ordered the Niterider Swift 500 and Cherry bomb tail light. I really want the side light function. Reflectors don't work unitl you're already in the headlights. I'll update when they get here. I'll probably keep using the older offroad lights during the day. The faster strobe makes it look like you're approaching faster (IMO) which on a BBSHD you probably are.

          I got the Rydesafe white wheel reflector kit. Added reflective brake surface strips to my Mavic Crossride /26x2.0 Schwalbe Kojak slicks street wheelset. Lots of extra decals on the paper so I did the sides and front of the fork, seat satys, and even worked a couple 1/4" pinstripes into the KHS logo on the downtube, and between the cables on the top tube. They're very unobtrusive during the day on the aluminum powder coated XC frame. They come in black reflective ( and colors) also if you have a stealth bike. Off road bikes,wheels, pedals and tires tend to not have reflectors. If you're riding street on one you really should look into this. On 26" wheels there's enough left to do some repairs if you tear them up offroading to some extent. I'll see about getting some Photos up after dark.

              The top tube, wheels, and downtube reflectors are juat 1/4" strips. The ones on the fork and shock are bigger.

                For DIY, 3M Scotchlite conspicuity tape is highly reflective, and comes in black, too.

                  Yes it's the same stuff, and there is reflective paint also. But the decals curved for bicycle wheels are very handy.

                I just got the Niterider Swift 500 street headlight, and the Cherry Bomb 35 tail light combo in today. The tail light is very bright in daytime flash mode, and has a soft night strobe also. 2 steady state settings also.
                I have mixed fellings about it's side marker function. It's there but just light scatter through the lens, no actual LEDs visible from the side. One big plus is the strap mounting that allows it to easily be moved to any bike as needed, and the reflector function provided by a textured chrome panel behind the LEDs. My Bontrager, and Blackburn lights don't have that. When they're out ( or forgot to be turned on) you've got nothing unless you installed separate reflectors. So overall I think it's a winner.
                I'm comparing the Swift 500 to other Niterider offroad lights because that's all I've ever used. Tough, weather proof, more than bright enough. The older ones had a very agressive strobe that trail users objected to.
                But I'm a street rat and agressive is what get's attention around here. The swift 500 has those qualities except a slower strobe, and the light is a softer, wider, and more even flood type of beam. Also added was a side light function. an indirect fiber optic effect through the lens side extensions. Bright enough to be seen from a distance. But the compact light, and moveable mounting makes it possible to lose that function by blocking it behind other things on the handlebars if you're not careful where you mount it. Especially on flat bars. The beehive lens keeps oncoming traffic from looking into the LED unlike the offroad lights.
                I have mixed feelings about the strap only mount. I have hard mounts (one of them straps on) and a helmet mount that all my 3 other Niterider lights can be swapped around on. To carry a spare light I still need a hardmount on the bars to use it, or to have the agressive strobe I like. All 4 of my NR lights have a different mounting. The oldest is my favorite. It has a triangular thumb screw and hinged bracket that just doesn't move around unless i move it. I wish they would pick a mounting and stick with it. But it's too late for that now. If you're just getting into NR lights i suppose that won't be an issue. The Swift is a better commuter light in several ways than the offroad parts. I have a Nightrider 350 that's still in the rotation after 10 years or so. Mostly for day strobe, but not because it isn't bright enough. It's just a bit larger to carry around.
                Nierider makes actual see where you're going headlights. Not little "look at" me things. I've waited a long time for them to make an actual street headlight. It's finally here and I like it.


                  Niterider has a new street headlight coming out soon. It's one of their Lumina series, so offroad rated construction. It's 1800 Lumens dual LED and has a street oriented lens with better beam control and side lighting that previous Luminas didn't have. Luminas have never been cheap, and this is a high end dual model so $150. All I can say is every Lumina I've owned is still running perfectly. A couple of them are 10 years old. It also has 2 strobe settings. Some people complained the old ones were too agressive for trail use. I complained that the new ones were too slow for traffic situations. These guys take their lighting seriously. Of course it has several lower output setting that allow extended run time. I almost never use the highest setting on my Lumina 750. From the size of it I suspect it has 2x batteries.
                  On a 1500W Ebike it's pretty easy to outrun your headlights.
                  Also it uses the Lumina mounting and due to it's size it should clear the handlebar clutter on an Ebike better and keep the sidelight visible.

                    I'm waiting for this to become available.
                    It seems expensive but it's about 1/2 of what their offroad endurance light setups costs, about double what their single Luminas cost. That makes ense because that's basically what it is. 2 strobe modes. These guys really listen to their customers.


                      I use this Fisher Fab House light. Made in USA. Luna sells it for $199. Has a flood and spot that operate at the same time. Has 4 brightness settings and a flasher. I forget the exact numbers but something like 300, 700, 1200, 3200 lumens. It is amazingly bright and it hooks right into the e-bike battery cable. Can operate from something like 24v to 60v.

                        So how did you wire it up .
                        I've got a Wolf V2 pack. XT-90(x2) discharge , can you use the spare XT90 ?
                        What cables/connectors does it ship with.

                      That's a nice light setup. I'm already into Niterider for all my bikes, and the side marker light function is a big plus for my urban night riding. But an E bike ready option is nice.

                        Yeah side markers really are a plus.

                      I'm diving into getting rid of the wires for my head light set up. I've been really looking at the Night Rider 1100 and 900 lights. I thought I was all in ready to go on the NR 900 then I stumble across this light from Blackburn. Blackburn 2017 Central 800 Front Bicycle Light the thing that grabbed me on this is I can buy a spare battery for it and just swap them out if I run out of juice and it comes with a gopro type mount already integrated in the light. Anyone else using one of these?


                        The Niterider NR 900 is an offroad rated light. Metal construction, but no side light feature. I've used Blackburn tail lights and loved them, but the one admittedly low end headlight I triedt dissapointed me. The sidelight function was kind of an afterthought. The NR Swift 500 works OK but I have to turn it up some and battery life suffers. I'd like to hear how the Blackburn works out for you. The price is good and at 800 lumens should be OK on low setting for anything except rural riding.


                          Figures...while the Blackburn 2017 Central 800 Front Bicycle light can still be bought on Amazon, Blackburn has discontinued the light. That doesnt give me that warm and fuzzy feeling and their other offerings dont really grab my interest. Think I'm going to go back to my original plan, sort of... NiteRider Lumina Micro 850 gonna pick up a pair of those. Glad I looked at all the NiteRider Lights before I went with the 900 boost. All of the boost lights the big number is from what they say is to use as emergency light mode sort of thing. So they would be running at the medium or high setting majority of the time. Well when you look at those numbers the Micro 850 bosts better illumination and run time. I subscribe to the two is one, one is none philosophy especially when it comes to lights so a pair of these I think will have me covered pretty well. I also just used a screw in nutsert to add a permanent mount for one of my Princeton Tec Vizz Headlamps to my helmet I think it came out really well. Ive used the Vizz as a stand alone bike light in the past mounting it to my handle bars and still carry a spare in my breakdown kit.
