Yeah man ebay does NOT = junk what so ever but they do sell alot of crap on ebay. Just for example my halo headlights are from ebay they're almost a decade, yes a decade, old...Halo's still work, and 0 problems or leaks. Point is just figure out what ya want and then you can find it on ebay for killer deal. I dunno what they're called but they look alot like stock tails mostly red with a clear reverse spot and those are very popular and seem to be good tails for the most part IMO
Also as far as actual LEDs go I had terrible experiences with superbright lots of complaints of LEDz burning out after a month. Hell I ordered 6 for my cluster. Only 2 worked. I order through a forum member (from gmfs) but he's great and his lights are TOP shelf. Plus you can tell him exactly what you want and he'll get it. I've been goin through him lately and I'm very pleased. Superbright can get confusing real quick to figure out exactly what you want vs. him I just tell him and he makes it happen.
As far as actual LEDs for the tails I've heard the actual brake lights are a waste but if the new tails don't come with LEDs for the reverse I've heard actual LED reverse lights are worth the coin.
Also, another thing I've found a lot of forum members don't know about is switchbacks. Simply youtube search switchback turn signals....They make these for our parking lights up front. You're welcome.
