Ok I noticed that on low-beam, my driver's side headlight is out. So I'm like "Crap! Gotta replace it!", then I put on my high-beams, and all four are lit up. Now I'm like "CRAP! I've got an electrical problem!" Can you guys help? I don't know how to trace this stuff down, but if you tell me to test something with a multimeter or something, I can do that lol - I just dont know where to start for s weird problem like this. Thanks.

 

if you look on the back of the low beam you'll notice,that there is three prongs unlike 2 found on high beam,try this;swap suspect low beam with good low beam and see if this correct problem.low beam have 2 elements instead of one like on the high beams.this test is easy ,and best of all,IT'S FREE

 

like the low-beams have two different lights in them, so a different light comes on inside the low-beam when high-beams are put on? Ok, I'll see what I can figure out.

 

yup, that is it perzactly.i'm sure this will solve your problem

 

K thanks. Knowing this, I bet you're absolutely right.
