F14....you would need to check the contacts on the bottom of the bulb to compare and get size comparisons for the base....on the side it says its a GE90 bulb and doing a quick google search they do show replacement LED bulbs for attwood mast lights looking the same...
That other bulb you would need to pull out of the socket to verify but based on looks alone id guess that's a 194 bulb and super common in LED...i buy those 20 at a time off fleabay cause they all cheap china stuff and never last more then a few years....i seem to be changing a bulb on my truck every other month now! i should just go and change them all just dont have the time right now

Thanks, I see Type 168 on the bottom picture panel and that shows a lot like 194...probably close enough!

Okay, additionally there are six lights tucked up in the seam/gap in the couch/table area. They are hidden by between ceiling material and the side wall panel/piece. I can barely reach up there BUT I can feel a cover...how do I get those open to replace those bulbs?

I have not figured out how to get to the six ceiling perimeter lights yet BUT...I did find that the two DSRAM 5008 swithable spotlightes did NOT work with new LEDs. Turns out the polarity was reversed and since the 5008 bulbs can only go in one way, I had to switch the wires going into the light socket. Works 100% now!
Thanks all.

I responded to your Facebook post.

The perimeter fixtures are attached to the facia and then the whole thing is affixed to the boat. You have to reach up in there and pop the covers off and pry out the bulbs. They’re a festoon-style bulb.

You can replace the bulb and then “attempt” to put the cover back on - you may or may not be successful! The cover helps to disperse the light as well as acts as a heat barrier (not needed with the LED). An enclosed LED bulb should have the same effect for light dispersal.

Copy all!
