Just attempted to wire up the headlights on the 27 Coupe, I'm using a standard wiring harness, the passenger light works fine and the tail light is fine but the drivers bulb is very dim. I have tried swapping bulbs and no change. Any help for the electrical challenged would be greatly appreciated. Harv.light

take the drivers lamp base out of the back of the socket...exchange the wires...put it back in.

If it still stays dim...you have an isolated ground condition and you'll have to see how to get the housing grounded better

Try sanding the grounding areas. That was my problem, needed a better connection

I had a similar problem recently with the left headlight on my '15 which has dual contact single filament bulbs. The socket on that side had a broken spring. It was barely making contact with the plug. Luckily I had a box of NOS headlight contact assemblies and swapped the old one out for a new one.

The way the light is made, there is a sleeve pressed into the outer bell shaped cover of the light. The socket is inside this sleeve and has a screw and spring for adjustment of the focus. It is through that sleeve that the ground is made to the socket. That area tends to rust, especially if the car has been left outdoors in the weather. It might need to be pressed out, cleaned up and pressed back in. Other areas to check are the light to fender connection. I think you have a bad ground somewhere.

Thanks to all, This site is the best. I wasn't getting a ground where the light body attaches to the bar. Too much paint, after a little sanding problem solved.. Thanks again to all of you. Harv

That dim light appears to have both elements lit and dividing the voltage, like one wire is going to ground and the other one getting the 6 Volts.
