Hey guys, I have a question concerning my lighting. Little history first. All things new, wiring harness, dimmer switch, all light sockets, newly refurbished light switch and all new bulbs. I still have a six volt system. All the lighting works, cowl lights, tail light and brake light, head lights, high beam indicator light and dash lights. The problem is the passenger side is not as bright as the drivers side. I feel like it a grounding issue. Any help is welcome.
By the way, great work JD on the gauge work and light switch!!! Thanks again....
Steve

Providing that the bulbs are of the same candlepower I would say bad ground. I would hook up a temproary ground wire to test.

agreed, and to ensure it is not a bad bulb, swap them left to right and see if the passenger side stays dim (ground issue) or if the drivers side goes dim (bulb).
i had to chase a ground last round on my 1929 with the head lamps. I did what Gene talked about, running a direct ground and if you touch ground wire to the socket does it get brighter ?? if so time to find where you are loosing ground. i traced ground from bulb to chassis and made sure metal to metal at every point.

Tail light or headlight? They are two different systems so I assume it’s not both. If it’s a tail light then it could be a ground or it could be the bulb. There are two different candle power bulbs for tail lights and you could have one of each. Step on the brake and check to see if the brake light bulbs are different. Double check their numbers.
If headlights, there’s a couple things to check. The ground, the reflector itself as one might have lost more of its silver, the bulb, and a common mistake, you have the low and high beam wires in the wrong position on one headlight.

If it is one headlight brighter than the other the bulb may need to be rotated 180 degrees. The way to tell is turn on the headlights and then switch the "dimmer" switch. If the bright light switches sides it is the bulb orientation.

Thank you guys! Just as I suspected it was a ground. When I put a wire to the ground post on the battery then touch the housing the bulb lit bright. DC voltage is crazy.
Thank you all..
