Probably just a bad filiment in the headlight. Swap the bad one with the corresponding good one (insides or outsides) to see if the location of bad one changes. If so, replace.   Mikemkapp78792006-10-23 14:19:47

So...you have four lights...2 hi/los, and 2 highs only, and only three of the four work, but only on high beam?
The two high beams will only work on high, so that's no problem, but...you don't specify which of the four bulbs work!(both lows & 1 high, both highs & 1 low?) The two hi/lows should work either way, but...you only have one that works, and it only works on high beam.
You either have two bad bulbs, or bad connections/grounds on them.   

or...a long shot here...a bad high beam switch.Adams' Apple2006-10-23 18:16:24

Here is the straight skinny:
 
With the light switch pulled out halfway, the parking lights come on. (good).
 
With the switch pulled all the way out, the lights pop up but only the far right light (passenger side) is on.
 
With the brights on, only the OTHER 3 lights are bright, the far right one (passenger side) is still on regular.
 
Does this sound like I just need bulbs, or a switch might be bad?  Don't want to get taken for a ride....
 
thanks

guess there are a few options what might cause the problem.


the switch is an option , or something goes wrong in the high/low beam switch on the steering colum...  bulbs.... i guess you need to check the whole circuit of option till you find the prob.

Sounds to me like the high beam filament in that bulb is gone.  I would first replace it with the one from the other side.  Could just be a bad connection in the high beam side.  Look for a loose or corroded connection.
