Unless you have projector lenses, HIDs are a no-no, you get a poor beam pattern and dazzle other road users. You also need additional things to go with them for an MOT (Self leveling system and headlight washer jets)
Ive tried a few different Halogen bulbs over the years, even the blue coloured 100W bulbs, and the best Ive found are the Osram Nightbreakers! I have them fitted to my Eunos, and with a reputation of poor headlights, these are like the HIDs on my BMW in terms of brightness, and you still get a good beam pattern from the reflector lense.
You can buy them from Eurocarparts, but they can be had on eBay even cheaper.
There are a few variations, the Nightbreaker Plus are about the best VFM, but they also do a "Gold" Edition, but Ive not tried them to see if the extra £££ is worth it.
Nightbreaker Plus everytime!
