My Hella Lights :: High Performance Xenon Blue Bulbs
i run these in all of my vehicles.
they were engineered to outlive sylvania silverstars...then sylvania came out with ultras, which apparently are on par with the hellas but still don't necessarily have the same bulb life.
they are a bright, white light. the class isn't coated - it's actually that color. they found the right balance between color temperature (whiteness) and output, since many tinted bulbs appear like they let off more light but in actuality they don't.
if you are looking for the absolute best light that is compatible with what i believe you have in that thing (9005/9006), then you should consider HIR bulbs. they have somewhat reduced bulb life vs. traditional capsules, but are on par with most performance bulbs. ideally, without increasing the wattage, if you want more/better light, you typically give up something, and most of the time that is bulb life.

and here is the 9006...the toshiba "globe" style are no longer available in 9012/9006, so this is the equiv

you asked about HID - HID is great but putting HID in light housings meant for a halogen bulbs is dumb. it is illegal, it scatters light and is dangerous/seriously annoying to oncoming traffic.

people claim they are able to control cut-off (which partly causes trouble with oncoming traffic) with different techniques, etc, but the only real way to integrate HID into a halogen housing is to retrofit an OE HID projector setup from cars like lexus or acura into your housing. people do this, but typically not on '95 cieras, hehe.
