Light conversion?

Not legal in the USA...only in Canada.

I have just the standard halogen bulbs you can buy at any parts store, and they work well...the headlights are almost as good as a much more modern car, especially with relays.

If you don't have a set of relays in the car, spending any money on bulbs is kind of a waste. The relays and normal halogen bulbs make it work pretty well. It will at least be as good as an early to mid 1990's car.
