there have only ever been two wires coming out of the back of my brake light and only one light bulb. ok fine, one of the wires is ground and the other is power.. well where does the extra brightness come in? because normally the light is on all of the time and just gets brighter when I activate either the front brake light switch or the rear brake light switch. so i guess im asking how do i wire that up.?
Functionally, you have 2 lights (1 light bulb)
a brake light and a running light.
most aftermarket lights are made for Harley
which uses the frame as the 3rd wire for ground.
