20pcs Super Bright RV Trailer T10 921 194 42-SMD 12V Car Backup Reverse LED Lights Bulbs Light Width Lamp Warm White

Replaced all bulbs in our ca.per .uch brighter and nice white light.

These are amazingly easy to install and extremely bright! They are very cost efficient!

Awesome there nice and bright but only work one way so if it’s not working just turn them around and try again

The listing says these will replace #921 bulb. I had 24 #921s in my travel trailer. I bought these as replacements.First problem was that these inserted in my sockets with much difficulty, or not at all. A visual inspection showed that the glass #921 bases are tapered to gradually slide into the socket. These LEDs have plastic bases which have a square, blunt end. They run into the socket's contact springs. I needed to modify each LED base by (1.) bending the contact wires away from the plastic, (2.) filing the plastic so it was tapered like the original glass bulbs, and (3.) bending the contact wires back into grooves in the plastic. After doing this (sometimes twice) these did go into the socket with a lot of force.After installing some of these in some of my fixtures, I compared them to the original #921. These definitely have a much more blue color than the indandescent bulbs (which were rather yellow). The brightness of the LEDs seems roughly comparable to the #921. These do *not* look any brighter. Official specs on the #921 are 265 lumens. So I doubt that these LEDs are 500 lumens (as claimed in the listing). Of course part of the problem is that one face of the LEDs is aimed directly at the reflector in the ceiling fixture, and that light just bounces back down and illuminates the LED itself, *not* the room.Do they work? Yes. Are they disappointing? Yes. I will use them temporarily, but I've already ordered another model LED which should be much brighter.If you want an LED replacement which is roughly as bright as a #921 incandescent, and you don't mind wasting ~5 minutes per bulb filing down the base of each bulb so they will easily fit your socket, then these probably will work for you.

excellent price . dealer was twice as much!! easy install

Seems like a nice product but I received the wrong color tone bulb. Much warmer than I wanted. Unfortunately had to use them anyways. Otherwise, they are bright and fit great. Easy to replace.

These give off a very warm and decently bright light. Can barely tell they are LED

Replaces old bulbs in rv direct replacement huge difference in light and 1/4 power usage. Grea product. Be careful there is polarity issue. Meaning you can put in backwards. If don’t work reverse and voila! Great product to upgrade in your RV.

These little lights worked well in my RV and living quarter horse trailer. If you want brighter lights, these are wonderful

Great value, would buy again.

Donne une luminosité blanche.Très satisfait

Not big enough for the inside of an RV only for marker lights or tail lights. They fit in the socket but won’t be bright enough for a bigger space. Unfortunately!
