LED lighting problems?

[eskaeone]

Hello all,
I recently changed all most all of the lighting in my 01' 4.4 X from stock to LED. some of the lights are holding up, others are burning out too quickly. For example, I got the sonar LED tail lights about two years ago and now all but one side of both sets of tails are not functioning. Meanwhile, I've had a set of sonars on my other car for 5 years with no problems at all. Any idea as to why this is happening?

Thanks for your help in advance.
