LED lighting problems?

[X5SND]

Here's what I've noticed.......

Some led bulbs seem to be more susceptible to failure in our trucks than others. Ive been running LED bulbs in the front markers and rear turn signals without any sort of coding whatsoever for well over a year with out any issues. The bulbs I'm currently on are just basic SMD can-bus led bulbs from autoillumination.com which do on occasion "strobe" but its at about 5% intensity and maybe 5 pulses total rendering it nearly irrelevant. That being said, I had another set kicking around (again from autoillumination.com) which were non-canbus chipped bulbs, and of a different chip configuration. These went crazy on start-up and had burnt out chips (each chip contained 3 LED's) after only a matter of minutes.

Now I'm just thinking out loud here....
I don't think its the actual "pulsing" on-off that kills them (led's can handle on-off switching just fine) but rather the current contained therein. I HIGHLY doubt there is enough heat within the headlamp housing around the marker bulb area to cause failure on that level.

In the same boat, got my turns from auto, good to go no problems but everything else, well thats another story..lol
