Was thinking I would like to change out my guage light bulbs for blue led bulbs to match the rest of my interior lighting. Has anyone done this. Or can shed some info on the bulb size.
Gaffrig guages.

You need to pull the bulb but should be a 192. You might have white bulbs with red bulb condoms in there now. I wouldn't do blue if you boat at night, your eyes will have a hard time adjusting. If your hanging at the docks showing off no big deal.
