Also, when you install them, LED's have a polarity, so if they don't light up, flip them around and try again.
If you're just looking for LED bulbs, me and other forum members have good luck with either Diodedynamics, or vleds. I personally have used one of these pairs on different cars:
5K WHITE 3 CHIP 5 LED LIGHT BULBS 194 168 158 2821 | 1 PAIR
for 3 years now, and they still work bright and strong.
