There have been many that have 'updated' their headlights. There are several how to threads that should come up in a search. Search "install angel eyes".

Headlights made, if I recall correctly, prior to mid 2002 can be baked open. Those mfg. beyond then are permanently sealed. That said, I had one of each and was successful opening the one permanently sealed. I wouldn't do it again.

My guess is that the majority of owners that upgrade headlights purchase new headlights such as those from Depo. Doing the upgrade takes considerable time and patience but it is not difficult.

I wired my angel eyes so they come on when the doors are unlocked or opened. ignition on and in all headlights on positions.
