How do you replace headlight bulb in Volvo 240?

I was wondering the same thing, but gave up and just decided to give the light assembly a good look and this is how I did it.

1. To remove light cover, tilt the bottom of the headlight up. It should become loose enough to remove and expose the bulb. If it isn't loose enough you may have to unscrew the blinker assembly cover. (I had to only on one side.)

2. Pop open your hood to view the back of the bulb assembly. You'll see that the existing bulb has a notch helping to hold it in and if you push down on the notch, the notch should pop out of the holder.

3. Pull the piece with the holder and it should detach from the bulb.

4. Now, twist the grooved plastic washer surrounding the bulb. I don't remember the direction, but it doesn't take much to turn it. Remove this and place to the side.

5. Moderately pull the bulb in the direction of your engine. It should come out.

6. Take the new bulb and place it where the old one was. To get it to go in all the way, you may have to twist it to fit in the notches (this is where having the light cover off helps).

7. Once the bulb is in, you can just do all the previous directions in reverse, and then repeat for the other side.
