Just picked up the Sylvania cool white LEDs. Going to try them out. Not as bright as I would like but works and hopefully will last longer.
I've always used cheap amazon/ebay LED's in all my vehicles and always had issues at some point with them. I as well went with the Sylvania cool white bulbs for my interior and starting to work on the exterior now. They are the Super Bright Sylvania 6000k with the lifetime warranty. They are insanely expensive compared to what I usually use but I doubt they will be an issue down the road.
As far as them not being bright, take the sunglasses off! The stock bulbs don't even compare to the brightness of these!
