921 bulb low light replacement or 12v dimmer possible?

I find that the lights are much too bright at night when I just need to see enough to move around. What are compatible lights to the 921 socket that would put out less light or is there an easy way to add a dimmer?

Drop into your local Auto Parts store or department,

A standard Wedge Base dash indicator lamp will fit nicely in the 921's socket, let me see if I have a number handy.
Number 168. You do need to be careful to center the lamp in the socket when you install it though, Bit narrower.
Home was where I park it. but alas the.

I replaced the 921 lamps in two fixtures with a 921 NA which is just the amber version and much easier on the eyes.

How dim do you want to go? Do a search on eBay for "T10 led warm white". Something equivalent to the 921 bulb would have about 24 5050 leds, so 6 5050s would be about 1/4 as bright, and so on. Some use 1210 (3528) leds which are about half as bright as the 5050 led. Take your pick.


I'd like the one over the bed to be as dim as possible. Possibly keeping only one of the two bulbs. I read on my ipad so no bright light needed at all there.

I'd keep the one on top of the kitchen table and cooking area as bright as possible.

Also will probably pick up a nightlight for the toilet and use frontal led when I am without electricity.

For electric camping, we added a couple of blue LED plugin nightlights with plastic nautical shapes- lighthouse, sailboat, seashell.

They seem to be just right for night movements, including in the bathroom, so no instant sunlight when nature calls unexpectedly during the wee hours.

Won't help for boondocking, but they are only a buck at dollar store and we're on season 3 for a couple of them ๐Ÿ˜‰

I have found that the bulbs at home depot or lowes for 12 volt lawn lights work just fine in place of 921 but 7 watts

I replaced my incandescent bulbs with 1210-36 LED panels.

Take the bulb that fits the socket to a NAPA store. By using the number on the bulb they can look up other bulbs of less lumens,(Brightness) that will fit.

The 921 bulbs also get way too hot, I replaced mine with 48SMD LED panels. I get more light and a lot less heat. ๐Ÿ™‚
