Bought a 67 Camaro and having trouble with brake and tail lights. Took it to electrical shop who kept it for 2 weeks. Now, headlights work, signals work, park lights work (front), but tail lights, brake lights and back-up lights don't.
Here is the head scratcher. Occasionally, the tail lights and brake lights will come on. We've seen them, but they don't stay on. Another curious occurence is that the tail lights, when they are on, seem to brighten and dim as the engine accelerates.
Any assistance, pointers or suggestions welcomed!! Appreciate it.
