I checked and didn't see a thread on this, so I thought I'd post something. I've completed the wiring for my rear lights and everything finally works except the tail lights. The bright filament works when hitting the brake, but the dim filament does not light when I turn on the headlights via the column lever. I have not hooked up any of my front lights yet to confirm if the headlights at least work ... that's next on my list to at least try. I haven't yet gotten a chance to look through the wiring diagram.

I have tried my taillights with the engine off and with the engine on. Same result.

Any advice?
