One Headlight Dimmer Than Other

likengtj · 07-20-2003

Sorry to start a new thread on this. Try to find a similar posts but had no luck.

Problem:
My passenger side headlight is about 1/2 dimmer than the driver's side.

What can cause this?
Any ideas on where to start?

BTW:
They are both brand new halogen headlights and the old ones behaved the same way ....

Probably a bad ground. Have you rewired the headlights yet?

Check to make sure the wires are connected to the headlights correctly. You may have a low beam wire hooked up to a high beam terminal. Maybe it would make the one beam brighter, maybe not.

when you say one light is brighter than the other, is it looking out from the car, or looking into the lights? i thought i only had one bright headlight until i adjusted them correctly.

I also had the dim light problem until I found that the PO had miswires the lamp socket when he /she put in new ones. Good luck.

PO told me he did rewired them ... unfortunately I'm starting to find out it seems his quality of work was not up to par. Oh well, these are the thrills and emotions of being an OPEL owner.

I will try your suggestions:
1) check for bad ground
2) check for wrong connection to terminal wires (low/high switched)

and my last option:

re-wire it myself and therefore be sure things are done correctly.

Thanks to all for the input, I'll keep you posted on my findings.
