LED Install Problem (Tails)

[Betrivent]

I do. We checked the elements in the back when the car was on, with driving lights, and when brakes were applied. It seems that the driving lights come on fine, but the wire that provides the extra juice to amplify the brake lights don't come on.

There's no amplifier. Basically, two circuits supply power separately to the two filaments of the bulb (one of which is brighter than the other).

On the bulb socket, the black wire is ground, the green is the tail light feed and the red is the stop light feed. If you measure red to black with the brake pressed and green to black with the tail lights on, you should see 12V on each.
