Arcon 16792 #1895 Incandescent Bulb 12V 3.2W, 2-Pack

If you run an RV or a boat with 12-volt interior lighting, the Arcon 16792 is one of those small parts you'll want a spare of before you actually need one. It's a #1895 incandescent miniature bulb rated at 12 volts and 3.2 watts, and it comes two to a card. So when a dome light or a reading lamp finally goes dark, you've already got the replacement sitting in the drawer. It's a simple part. But it's the kind of thing that's genuinely annoying to be without when you're parked for the weekend and one fixture quits on you.

The #1895 is a standard miniature bulb number, which makes this an easy, like-for-like swap. If your fixture originally ran a #1895, this one drops right in. It uses a BA9s single-contact bayonet base, the small push-and-twist style found in a lot of RV and marine cabin fixtures. You press the bulb in, give it a quarter turn, and it seats. No tools, no soldering, nothing fussy about it. If the bulb you're pulling out has two tiny pins on the sides of a smooth metal base, that's a bayonet base, and this is the right replacement.

Where does it end up? Dome lights, overhead cabin lights, reading lamps, porch and entry lights, map lights, and some small gauge or panel illumination. Basically the little warm-glow fixtures that run off your house 12-volt system. At 3.2 watts it's a low-draw bulb, so it's gentle on the battery bank during an evening at anchor or a night at the campsite. That matters when you're running off house batteries and watching every amp. And because it's a standard size, you're not locked into one fixture to use it.

This is a true incandescent bulb, not an LED. That means warm, familiar light with the color and glow a lot of people still prefer in a cabin or bedroom fixture. It's also the correct choice when you simply want to match what the fixture was built for, with no flicker, no driver, and no compatibility guesswork. Incandescent bulbs dim smoothly too, so if your fixture is on a 12-volt dimmer, this one plays nice with it.

Because it ships two per card, you're set up to keep a spare on hand, and we'd tell anyone to do exactly that. Interior bulbs always seem to burn out at the worst moment, and having the second one in the junk drawer or the parts bin means a two-minute fix instead of a trip to town. If you've got several identical fixtures, grabbing a card or two is cheap insurance for the season. Keeping a matched spare also means your cabin lighting stays consistent, same brightness and same warm tone, across every fixture.

On voltage, it's rated for 12-volt systems, which is exactly what the house side of most RVs and boats runs. Match the #1895 number and the 12-volt rating to your fixture and you're good. If your old bulb was marked differently, check the number stamped on the base or printed on the original packaging before you order, so you get a correct fit the first time.

Arcon has been making RV and marine electrical parts for years, and this bulb is a straightforward, honest replacement part, nothing more and nothing less. Order the two-pack, keep one in the fixture and one in reserve, and you won't be hunting for an oddball bulb mid-trip. We ship in-stock orders the same day when you order before 3 PM Eastern, so a replacement card is rarely more than a couple of days out. If you're not sure it's the right one for your setup, reach out and one of our techs will help you match it.
