I was just wondering if tehy make a head light for the 94 Zs that you don't have to buy the whole thing everytime you replace them, you could just unscrew teh bulb and replace teh bulb like most lights.. Do they make something like that for our cars??

 

nope. there have been people who glued in new bulbs into the existing housing, but everytime that one of mine has burnt out, I just went out and spent the @ $20 for a new one.

 

A Hella FF75 or 90mm conversion will do this while providing much better light than stock. The FF75s are an easy install. The 90mms are more involved (and round) but have the added benefit of being DOT legal. Here are some install pages to check them out:

The FF75s have been had on Ebay for around $40 a pair. The 90mm projectors are around $60 each.
