Led problems

[pebbleboy]

I have led from early classic on my truck. I purchased them about a year ago. I have been having problem with my tail lights not working and then working again. I replaced the wiring from the firewall back and also a new headlight switch. I find out today that the resistors at the bottom of the leds have come off and thats the problem. I'm a littled steamed not because I purchased those parts because I needed them, but because the most expensive part is the one thats broke.

Has anyone else had problems with those leds? Im going to call them tomarrow and see what they say but Im not holding my breath on anything great.
