There is no individual bulbs for the dash indicator lights. You have to change the entire unit.
69200124 WIRE HARNESS CONSOLE $72.02. Per the parts list at Dodge City HD. '06 was the last year of the individual bulbs IIRC.
Perhaps a good electronic shop could replace the LED??
tourbox
Tourbox has the best idea, replace it if the led lamp has power but not working.
Instrument repair shop can replace the led lamp but from my exp the 2 things may happen are, different brightness and the repair price may be higher.
