true halos are gas discharge lights with transformers right? so the question is this. I want to change my oo 5281 over to the late model lights. do i need to change any relays/fuses are the complete sets on ebay true halo/gas discharge or are they cheap imitations also has anyone actually done this...thx

"halo" refers to Halogen bulbs, which are a high filament temperature resistance type bulb. Xenon's are gas discharge bulbs that require a ballast.

The conversion to the later projector head lights with "angel eyes", which is what I assume you are looking at, is compatible with the car's electrical system. Conversion to gas-discharge headlights (Xenon's) is more complex and more expensive.

They have angel eyes with halogen and angel eyes with xenon (which you referred to as halos, correct?). If you want to convert to xenon, I think it will be compatible but you might need different wiring. If you buy new they should provide the wiring required for the conversion. I remember that you need an extra cable to power the angel eyes.

thx , ya i had the terminology wrong . i like the look of the Angel eyes.I just thought if i was going to the trouble i might as well install the xenon also and get the brighter lights .I do a lot of night driving.
