Lower left headlight fault

07-28-2010, 09:09 AM
Ok so I am guessing that the bulbs are gone. Wanted to ask a question or two before I go bop money for some new light bulbs.

if the halo's are still on, does that mean its the bulb and not the ignitor or ballist?

How can I discern which component it might be?

are your low beam lights not working? if its the low beam u might just need a new bulb. you have to start with that

Well the driver side headlamp is not coming on. So i assumed it was the issue with the ballast. I thought the headlight would have indicated headlight if it was a bulb problem? Right?

Start by swapping headlight bulbs, then ignitors, then ballasts between your driver and passenger side until the problem follows it. These cars aren't too good at telling you the specific part of the headlight assembly that has a problem, only that a problem exists.
