Does anyone know why I would have one bright (normal) and one dull headlight on low beam on my Excel? I've noticed this on other vehicles before but never had it happen to me. Any suggestions greatly appreciated.

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

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.

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.
