Head lights

ebang · 06-18-2007, 04:30 PM

I noticed that the right headlight is far brighter than the left so I decided to change the left with a new one and onced replaced it is still the same...it is a lot less bright than the right..Is this normal?

I think he is asking if you swapped the left bulb over to the right side and right over to left and see if the brightness goes with the bulb.

also see if you're headlights are aimed correctly. One could be aimed higher or lower than the other. Drive up to a wall of some sort when it's dark out (garage door works well), park about 15 to 20 feet away, and look at where the beam concentrates at for each headlight. If it's about the same distance up from the ground, then they're pretty well aligned.

did you check your fuses it might have blown its near the battery

Alignment is a possibility.

Usually it's wiring.... 20yo OEM 18ga wiring.

I rewired mine to run off the batt/alt and ran all new 10ga wire with new clips for the bulbs and my headlights are bright as day.

Ya switch the bulbs around for sure. It could be the bulb is mis-marked.

Allighnment is another good one because that will make 1 look more bright than the other one. I am guessing you have one that is noticeabley brighter than the other.

And just plain old crappy wire. Voltmeter time. Check the amperage running into and out of both sets of wires.

Fuse??? I think both of the lights would be out if a fuse was blown but that's just an opinion.

Did you touch the glass of the bulb during install?? If you did it could be trying to go out prematurely if you are running hallogens.

no, theres a fuse for the left side and a fuse for the right side

I will do some checking, but to add,.... when I turn on to high beam the one that is really low almost goes off completely.
