I got a few Questions about Bulbs , I kinda understand the double or single filament by looking in it. But i dont get what does what, are Tail lights single or double? Front turn signals? rear turn signals, marker or running lights, tag light? Brake light? or Head light? hope this isnt to stupid of a question. Im asking cause how the tail light can be made to be tail,brake,and turn signal with the integrator kit.
