headlights lights brake lights dim flash while engine is idle

My w108 when idling makes ever light on the outside of my car dim flash...gets bright then dims bright then dims. Is this an alternator problem? The idle is all over the place too by the way so I wasnt sure if that could be part of the problem as well. I am still trying to tune my carbs in perfectly after I had them both rebuilt. Thanks guys!!

You have a ground problem.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

I wouldn't rule out the alternator either. You can get the whole charging circuit checked at a Kragens or other general use auto parts store for free ...

Ground faults are a bitch to find too...
