LED BULB

I have 9 of them above my sink and they are one of the few I have not replaced with LED BUT I have a florescent light in the ceiling that I use instead.

Camping World has the incandescent bulb P/N 2099C .Yes the bulb is one contact bayonet stile.

Need to know a little more info. In our MH light fixtures, there are 4 different types of 12v light bulbs.
Pull a bulb from a different socket and look for a number such as 1041, 1042, 1076, 912, 921 etc. Bayonet base, wedge base. A lot of the e-bay sites use coding such as BA15d etc.
And then there is the colour, warm white 3500K, Daylight 5000K etc and the lumen output.
Lots of choices after you find the correct base. Yes, Hong Kong, China suppliers are a LOT cheaper. Just bought ours for about $2.00 a piece as compared to about $30.00 a bulb here. Took about three weeks to get ours.

Not enough info to answer your question. Go to Ebay and search "12 smd led bulb 12v" and look at the pictures to find the type of base you need. If it has a single center contact it's probably a 1156. If it has two then 1141. I like the warm white over the bright white for indoor use.
*I'll go out on a limb and say this is what you want.

I take the bulb to Walmart or auto parts store and compare. When I have # I order on the internet.
