To replace the headlight bulb, I first removed the wing nut (left arrow) and wing bolt (right arrow).

Pliers are sometimes needed to start them turning. I also found penetrating oil to be necessary because this area is exposed to the weather.

 Removing parking light or turn signal assembly, GM minivan, 1998. Then I removed the park lamp / turn signal assembly by prying with a big screwdriver from the back side by the headlight.


I pushed the parking light off to the side.

If the turn signal bulb or side lamp bulb need to replaced, I can turn the bulb socket to remove the bulbs.

When changing the bulb, this electrical connector needs to be unplugged.

This can be unplugged by lifting up on the ends of the blue tabs and pulling the connector out.

 Removing bulb retainer for headlight, GM minivans. I twisted the black bulb retainer and then I was able to pull the headlight bulb out.

Then the bulb can simply be pulled out and replaced.

Note: I did not actually replace the bulb in this case... so my pictures don't exactly show the normal procedure.


Note On Handling Headlight Bulbs:

Do not touch headlight bulbs with your bare hands, because the oil on your skin can ruin the light bulb. Use a paper towel or tissue to handle the new light bulb.
