I beleive optiblue is the company name.
taco, tried that, heh, I contacted sylvania about it and everythig. The 3rd brake light on the '95-'97 exploreres is some kind of luminesce or something like that, its based on the neon platform and is exact on and off like an LED. I talked to them about some sort of retrofit of this technology into some taillights, but they say it would be too much trouble for the profit (basically) they're very nice people, but not much on the helpful side hehe.
if you want just LEDs in your taillights, jamstrait makes a 15 LED unit that has a 3157 socket on the back. At night they are AMAZING but during the day its 2 round dots in your taillight, I wouldn't advise that kinda thing unless you have clears, the stock light may just confuse people or make them think you have a wiring problem.
There is also a company that does retrofit into classic cars using LED technology..
www.radiantz.com , I contacted them to see what they would charge to convert my clears to something like that but got no reply from them, its been like 3 months, apparently they don't want my business cos I would have paid a good bit for those.
what I'm sort of poking at right now is a sort of altezza approach that uses an LED cluster perhaps like that on the back of a fedex truck. Crystal lense, chrome housing with 2 round red LED clusters, I think it'd look pretty good, but its hard to describe, ya know what I mean?
