Alright guys, i'm here to help
As we all know, T/A stock lighting sucks ass. (I don't own mine yet and I even know this) Well Firebird's have sealed beam headlamps, the whole "rectangle" headlight IS the headlight. When i get mine, I want that obnoxious blue headlights for the car. If you wanna put bulbs in, check out this site: Google EuroLamps and on the site, left side, hit Sealed beam conversion kit. Email them your year and model and they should be able to help you out. Then I would go to ebay and find whatever bulb you want. I think the kit swaps them out to H4 bulbs. As the temperature in the bulb goes up, the bluer it gets. 10,000K is a deep blue that lights up EVERYTHING which is what I want, 12,000K is blue/purple. I think 8000K is what the mercedes and lexus's have. If this is too pricey, go to AutoZone and get Sylvania SilverStars.. they're more white than they are yellow. I had these on my 87 Camaro and they looked nice. But I prefer the blue tint more. Hope this helps.
