LED's not working right.

[rennaissanceman]

I just got my Super-bright led's in cool white today and put them in my truck in the dome and map lights. And they light up good and bright, but only when I open the door, otherwise when I just hit the switch they are very dim, not bright enough to light up anything, each gets progressively dimmer when another is turned on, and when you look closely you can see them occasionally fade slightly brighter and darker, and I have no idea why this is. Can someone shed some light on this for me?

If no one chimes in here. Email SBL's. I did when I had issues with leds in my '02 staying lit when they werent supposed to be. The steered me in the right direction, and helped me fix the issue.

My problem was all 3 LEDs needed a 1/2W 450ohm resistor or something of the sort from radio shack.
