One thing to consider is that the existing wiring, if it is original, will be taxed to its limits if you install some hi-tech headlights. Even halogens, though often used, are a good load. You gotta remember that the current that operates them goes through the light switch. How old it that part? Then, there's the dimmer switch. It ain't new, either, is it?

If you want some hi-tech lights, you need to consider upgrading the wiring (it's easy to do with what the vendors sell) and also installing a relay kit that will take the load off of the switch and let the relays handle the load. Then, it won't matter if you use Cibies, Hellas or whoever's bulbs.

But, in the meantime, go to WallyWorld and get you some new headlight bulbs, H6024's are just peachy, and don't risk driving in the dark when you least expect it.
