I have a 2004 dodge ram 1500 with the overhead compass, temperature, and trip computer. I noticed that the bulb that illuminates the lettering US/M and RESET was burned out. I thought it would be easy to find the replacement, but I was wrong. I have access to Mopar's Star parts and found the page with the module and it does not list the bulbs, it lists the map light bulbs but not the ones in the module. So I measured the base of the mini bulb and it is 8.5mm. It is not the same as the bulbs that illuminate the Air Conditioning controls or the same as the instrument cluster bulbs. I have also looked in the manual and it doesn't list these bulbs. I have ordered some Dorman bulbs that look similar but with no luck. Has anyone ever found out a part number for these. Thanks
