2 months later the switch is broken again. Apparently very poor design.
A road hazard especially at night.

I got fed up and removed the switch, study the design carefully. It is straightforward.

The use "plumbing glue" the stuff plumbers use to join PVC pipe together (You need a primer and a glue). This plumber stuff is unbelievably strong. Use glue only where needed to hold it together (You do not want excessive glue inside the switch!).

Tips:
- Glue only on the sides of both parts of the switch (the reason this switch fails is because of the broken plastic tabs taht are supposed to hold the 2 pieces together). Make sure glue does not get inisde because this can intefere with the function of the switch.

- While waiting for the glue to dry (which is very fast for the plumbing glue...about 3-4 minutes), hold the 2 pieces together firmly with your hand.
If you can hold the pieces together for 8-10 minutes it is better.
-Re-install the switch.

I did this 4 years ago, never a problem again! You can buy as many switches from Volvo (or through recall), the problem WILL recur, guaranteed. They failed to come up with a better design for a very important part. Imagine driving at night in the middle of nowhere and the headlights are OUT, not even the parking lights!

IMHO, Volvo should have designed the headlight switch that has the 2 parts held together by SCREWS NOT by plastic tabs!

I gave up on Volvo....Used to have a 1991 240 that was high quality...I am not impressed with my V70
