My cheapo 10 led lights for the front basket of my schwinn tricycle conversion ebike and the 12 volt converter has just red and black but the light have red black and white and I intend to wire the lights to a motorcycle multi-light switch (hi beam=lights on, and low=lights OFF) and then a horn. Do the lights require the "white" wireto simply switch on or off?
