Is it possible to install HIDS into the fog lights or headlights in these cars? I read somewhere that you can't really do it in the headlights without drilling and etc, and I haven't been able to find anything about to foglights. Has anyone managed to do this before? My car has the basic non xenon headlights.

 

You can do HID's.... You can do LED's but will need the relay harness or good resistors to get them to not flicker.

 

Yes, it is possible.

I have HID on headlights and fog lights.
But I suggest to buy a headlights with projector to use HID as headlights (and avoid dazzle people with the halogen housing)

For fog lights is just a plug & play.
You need a good quality HID since you could get bulbs warning with a cheap ballast.
You can play with NCS to turn off the warnings, but it is not the idea.
