LED problem - what's wrong?

I installed a 12V LED in the dash today to indicate whether my DRL's are on, but it burned out after about a minute. The LED had a 10k resistor soldered in series on the + lead, other than that it was just hooked up to the car's electrical system (12.4V engine off, 13.8V engine on). The resistor was to make it dimmer. After a minute of testing with the engine on it suddenly burned out. Earlier it worked just fine on the workbench with a DC supply of 12V-15V.

Any ideas as to what could have happened? Could it be fluctuations in the car's electrical system (I wasn't revving the engine)? Any suggestions as to how to wire the next LED, so it lasts a little longer? Remember: I'm no good with electronics, so be nice when explaining.

Thanks
