headlights ...

ok im putting some strobes in my head lights soon.
-are the 99 grand prix headlights sealed or no? cause i read somewhere that u cant install the strobes in the head lights if they are sealed.
-what teh difference between sealed and any other?
-if they are sealed .. are the fog lights sealed too?

thanks

no they arent sealed beams. they are a plastic housing in which a halogen driving light is installed from the back. same with the foglights. so just drill a small hole and install your strobes

ok thanks man! how hard is is to get the headlight housing out so that i can drill into the back? thanks

two bolts
