I am curious to know how one goes about to change the headlights (H4 / 9003) on the 90-94 LS??? Can anyone help?? I tried to find it in the manual, but there are no instructions to do that. Also would like to know how to change take the amber parking light housings in the front bumper out??

 

on many vehicles you have to access the ambers from the underside of the bumper...as for the headlights, there should be clips to allow the bulb assembly on the back of the light housing, or a screwout piece.

 

I have found the answer to replacing the "ambers" as you call them. And you do not have to get under the bumper. As for the headlights, i know that H4 type bulbs have a clip the you must remove to get the bulb out. My question is, how do you get to that "clip"???? do you have a 90-94 LS400??? I can't imagine, that you have to take things like the Air Filter housing out, etc. There has to be a better method, can anyone help??? Has anyone replaced the headlight bulbs??? thanks.
