SOURCE: HOW TO REPLACE A HEADLIGHT BULB ON A TOYOTA PREVIA

Replacing a headlight bulb for Toyota Previa. Quite simple. Open the hood. Look for the black plastic coupling or ring on the backside of the headlight. Grasp and turn counterclockwise (i believe it will be about a quarter turn). pull the socket out, then replace the bulb. I believe it is code #9004. Strongly recommend replacing both headlights at the same time.


Good luck

It could be the relay, which is a yellow box located under the carpeting in the trunk on the left side. It is a problem common to your model. Also, check the brake switch's (behind the brake pedal) functionality (12V present with key at ACC or ON and continuity between wires when button engaged).

i hope this helps

This is slightly counter-intuitive, but the plastic lens needs to go in and up before it comes out. After removing the two screws, use something thin and flat to pull down on the underside painted part of the wing between the two screws. A little bit of prying downwards. Two raised lips become visible - they are holding the lens from being able to be pushed up and in. A second pair of hands could help. Then use your thumbs on the lens close to the screws, gripping with your fingers on the top of the wing and squeeze up. POP!
