Sheesh! You were right, Tool Pants. I should have done that check first. It was weird, though: both filaments looked good at first inspection and then "disintegrated" when I tapped the glass with my finger. Odd.

So now the real question is: why did my headlights burn out at the same time? It was a wet night when they went out. Oh well, at least everything works now!

Thanks guys!

The story is that when one bulb burns out it causes a voltage spike to the other bulb and that one burns out as well.

I always thought this was an old wives tale. But I have seen enought reports from Boxster owners over the years that I am starting to believe this tale.

Believe it or not....

It's always funny when it something simple like that. To bad you already spent $115 on a new switch.

It's easy....

- instructions are in the manual and the tool (5mm) is in the tool kit w/ spare tire.
- Pop out entire light housing
- take off back
- disconnect wiring plug
- un-hook retaining wire (push down and move to side and release)
- pull bulb out
- insert new bulb (be careful to not touch glass w/ bare finger - use a towel)
- reverse to install

Fog / Low / High all use the same bulb - H7 (for non-xenon/litronics)
so it's easy to swap one bulb for another to test for burnt out bulb or in a pinch (if a low is burnt out - just swap w/ a fog or high beam until you can replace )


Tip - the loud bang/snap noise is good/supposed to happen when turning the release tool to remove and install the light housing. But after reinstalling, tug on enclosure to make sure it's seated properly. There are guide rails and knobs to assist in lining up back up for reinstallation. It goes in smoothly so don't force it.

PS - Pick up a 2-Pack of H7 bulbs when one side needs replaced. Personally, I find it best/easiest/most efficient to replace both sides at same time. If not you usually get/have to repeat on the other side w/in a week or 2 (as the bulbs were installed originally in the car at the same time right )
