The "crystal clear", "diamond back" etc lights are interesting to look at, but not the best at actually lighting up the road for you. For that, Hellas are good. Cibies, in my opinion, are better.
Get them here - this guy KNOWS his products and only sells quality stuff:

If you're going to run stock wattage bulbs, stock wiring is not bad on these cars. If you choose to wire in relays etc, I'd suggest getting the kit from Dan Stern as well. It will cost more money to buy, but it is GOOD, and I don't care for no-name stuff. There's usually a reason something's cheaper.
Cibies are expensive, but I am not sorry I bought them!
