Alright this problem makes no sense and any help is much appreciated. I have a Pontiac Sunfire and one of the headlights is very dim. I looked at the wiring and I found the strangest thing. Both lights are wired on one 15A fuse. At first I thought maybe the first light is taking all the power but the lights are wired in parallel. If both lights are in parallel then shouldn't they both get an equal amount of power? Why is one dim? I tried changing the bulb but nothing! What could be causing one light to be so dim? Would it be okay to put a 30A fuse on it (if that works that is)?

If I clean the ground wire are the light connector plug and it does nothing how can I access the ground wire further down the line? It just seems to disappear into the engine. Is it really bad to connect the bad ground wire to the good ground wire at the light?

Dim yes, oh you mean the car!
Read your owners manual for the correct fuse. If you have changed bulbs to no effect it could be the circuit or the replacement bulb. Take the bright bulb from the other side and put it on that side. If it is dim then you have a problem with the circuit and the wiring will need to be repaired or replaced. It is a safety issue so get it done soon.

Probably a bad earth,wrap a wire around the bulb,the silver bit not the base, put the bulb in the holder take the other end of the wire to a clean body area and if the light is ok you have a bad earth.Trace the earth wire from the bulb holder and clean where it makes contact with the body

DO NOT up the fuse! fuses are rated for a reason. Using a bigger fuse then the rating calls for can cause serious damage or fire.
Sounds like you have corrosion in the connector for the light that is dim. Or somewhere in the harness that goes to that light has a partial short or open.
Check the connector first, look inside for greenish color on the metal contacts. They should be brass colored. If they look "dirty" go buy some contact cleaner and spay into the connector.

You have a grounding problem. Locate the ground wire. Remove fastener, clean wire end & contact surface with abrasive cloth. Apply silicone to the contact surface & tighten.
If this does not rectify the problem, remove the plug from the headlight. Insert a small screwdriver behind the flat surface of the wire end. Remove the wire & clean. Before installing the plug, apply a little grease to the terminals.

Nope.
Bad ground wire to the body at the light housing.

I had the comparable problem. you do no longer prefer a extra constructive Alternator, or dry cellular battery. the priority is the Capacitor. It desires to be 3.0 Farad or bigger. I certainly have a 4.0 Farad Cap and have been given it for $ninety, and it handles a 2400 watt Fosgate amp without problem. as quickly as I had the a million.0 Farad Cap hooked as much because it, the lights fixtures could dim. So believe me in this one , it is the Cap.

you might have to replace the whole headlight assembly. that might be your problem to begin with . the light cover is plastic and over time from heating up so much it starts to fade thereby letting less light thruogh .you can also try a bulb with higher watts to see if that will solve the problem
