Please note: The service light your talking about is on the DC side, the 12 Volt indicator. Mine was out also and replaced it from Catalina Direct last year. (the Radio Shack did not have one in 12 Volt) Mine was not only snapped in, but had some type of glue on it, like clear goop. It still popped right out, and back in again. Remember to turn the batt switch to off to avoid sparks. Just as some hind sight: Mine did not work when I got the boat and went the first 1 1/2 years with it out. It bothers me when anything on the boat is not working as it should, so I replaced it. Now we find that, believe it or not, that little green light bothers us at night when sleeping in the back cave. The only way to turn it out is to shut power off, not a great solution. In fact I made a wiring change so that my fridge is direct wired to the hot side of the 1-2-off-both switch so that I can turn the panel off when I leave the boat but still have the fridge running, and the little green light off. (were at a slip on shore power)
