One bright and one dull headlight..

Hi
Three things to check
Check the globe to make sure the two fillaments are not touching
Check that only one beam is being supplied with power at any one time
Check that the earth terminal is clean and secure for that lamp

Sorry
One more thing make sure you have the correct globe fitted

As said before, but the usual one is the earth on the dull light is bleep e!!

The only other earth it can find is throught the other light, ie through two filiaments, hence the dull light!!

If the excel uses the switch to switch on the positives then you are set and it is a case of just checking the earth and prob just a little corrosion, but if it doesnt and it switches on your earth, well goodluck.

From memory most switch on the positives, only older Nissans used to use the Earth system (not important dont need to be corrected if that isnt exact!!)

Let us know how you go!

Matt.

Hi sometimes the parkers are in the headlights aswell, so the dull one might be a blown fuse, with the parker shining as bright as it can. Each headlight should have a seperatefuse under the bonnet.

Ensure the mud is cleaned off after you've been out bush!! :)

I had the same problem with my wife's Subaru, followed all the usual advice and ended up taking it to an auto elec, who found the problem in 5 minutes.
It was the plug on the globe had burnt out inside, 2 new plugs, 1 new globe, a cup of coffee at the Golden arches while waiting and $60 out of the pocket and no dirty hands, problem fixed now good head lights.
