LED TS indicators keep burning out?

are you supplying 12v to each LED? Do you know what they're rated at? What size of resistor did you wire in line?

I am supplying 12v to each one independently, and they were advertised as LEDs for auto application, 12v. I bought an assortment of resistors at radio shack and played with them with a battery charger until I got the brightness down to a reasonable level, don't remember exactly what was put in-line...

The LEDs look identical to the painless ones...

Most likely they are only the 1.5-3.4V LEDs (depends on color). Driving them with 12V would definitely overload them. Have a look here on a method to test your LEDs with a multimeter to see exactly what voltage they are rated at.

Then from there you can determine what size resistor you will need. I'm guessing you would probably need a 400-450 ohm resistor in series with your LED.
