They have made 12 volt incandescent bulbs for many years. They have the same base as a standard lightbulb, and fit the same sockets. They are used for campers with 12V lighting, and 12V trouble lights that clip on a car battery. Being incandescent, they drain a battery pretty fast. Thus LED would be much better.
We now can buy 120V AC LED bulbs that will fit any household socket. But do they make a similar bulb that uses LEDs, runs on 12V DC and screws into a standard socket?
Tail lights using LEDs are made for trailers and automobiles and have been for many years If you google " 12 V LED bulbs " you will find a number of sources for various styles and for various sockets.
What is used in campers and RVs nowadays?
Terrible idea to have a 12 volt bulb with a standard screw-base socket so that it could be hit with 120 volts by some unsuspecting granny replacing a light bulb. Where were the electrical safety folks when that idea came along?
Anyone remember the flashbulbs that looked like standard light bulbs even including the standard screw base? I always thought that the lamp companies made them that way just so that practical jokers could screw them into table and floor lamps to scare the whatever out of people when they came into a room and turned on the light. Big blast of light and maybe even a small bang as the flash went off.

Just bought a bunch LED lamps for Malibu lights (12V) from an EBAY store like these:

I hate to join the Google-team, but this one is so easy 12V AC LED standard base.

Professional photographers used them in those big umbrella reflector setups they used years ago. I remember a crime drama on TV were the criminal was replacing the regular bulbs in table lamps with the flash bulbs in order to stun the victims of his crimes. I imagine a lot of kids and teenagers who saw the show wreaked havoc across the country after the show aired. ^_^
TDD
My toaster has a 110V plug on it. Should I be concerned?
Aside from "screws into a standard socket", yes, there are tons of LED-base d replacements for automotive bulbs on the market. Some better than others. A lot are garbage.
The ones that have the round dome shaped traditional LEDs are generally gar bage. The ones that have LEDs that look like little square bits of clear pl astic are the good ones.
Look to replace bulbs lumen-for-lumen. Less lumens means less light. I usua lly go for more lumens, for more light on less power.
With all the old incandescents turned on in my camper you could barely see and it drew several Amps. The LEDs I replaced them with have 16 high-intens ity LEDs per panel, plugged right in place of the old "941" type bulbs. Wit h them all on, you can perform surgery it's so well-lit, and all together t hey draw < 2 Amps.
I dont remember the flashlights, but I do agree that those 12V bulbs should not have a standaerd screw base. They were made that way for trouble lights. I made an adaptor with 2 battery clips, wire and an outlet so I could use them on the car battery. I did accidentally plug one into an AC outlet once and fried the bulb instantly. Nothing spectacular, it just burned out. I always thought that they should not only make them require an adaptor, but also have some sort of markings on the bulb to easily identify it. (which they dont).
Pow! There goes $12.99 instantly on 120 volts.

I just looked at these. They're not all that many lumens, but I suppose using several of them would do the trick. But what does the base fit into? Would that be like the bi-pin sockets used for taillights or a dome light? Screw terminals that go right to wires, or what? The picture is not real helpful.
contact the source and ask?!
E27 12 volt LEDs will be rather scarse - but GU10s are very common.
What should it have had?
Would you say the same thing about the incandescent bulbs that have existed for decades, for indoor trailer lighting and 12v trouble lights?
I googled this and I noticed in one hit that many did not give a
110-volt-watt equivalence, like CFLs seem to do always.Many that did were only 25 to 30 watts. Those that used twice the current didn't have a watt-equivalent value.
Some give milliamps, Most give lumens, but you'd have to look on lightbub boxes to see how many lumens for a 75 watt bulb.
A generic incandescent bulb emits APPROXIMATELY 15 lumens per watt.
