My 68 coupe has thrown me for a loop.

Ok, this has me totally stumped. The drivers side lights, both front and rear are brighter than the passenger side lights. I mean headlights, parking lights tail lights. Can't figure this one out. Any help would be greatly appreciated.

Wow, very strange.

Brainstorming...
Thought #1) Passenger side lights are all at the end of their respective wire harnesses... could there be a possible voltage drop along the harness??
You may want to measure the voltages on the passenger side.
Thought #2) Did you rule out any issue with the bulbs by swapping them from side to side?

check your grounds

Yep, tried moving the bulbs around. I will try the voltage test.

Thanks guys. I will try voltage test and double check grounds.
