You know when you just feel like you are straining a bit to see things cause it feels dim inside your RV or motorhome? I did, until I bought these 12V Super Bright 921 LED Bulbs for my RV. I had other 12v LED lights, but for some reason they just didn’t feel like enough. I would have to turn on several lights just to feel like there was light inside the motorhome. Not to mention my wife likes plenty of light…

So we bought these LED bulbs and it’s just another level of bright. They don’t give that blueish light, which is what you generally think when you see a light bulb described as “super bright”. These are 3.8 Watts, 684 lumens, 6000K-6500K super white color temperature without the ugly blue/purple tint.

All the sudden my wife is turning on less lights, and it just feels brighter inside the RV.

We didn’t have any TV signal interference before with the previous LED bulbs, but have heard others complain. We have an LG LED Smart TV with HDTV antenna and Internet Apps, and we have not had any interference at all.

We purchase these Super Bright 921 12v LED Bulbs for RV, or Motorhome on Amazon, but there are also some similar ones on Ebay.

Question and Answers on these 12V LED Bulbs for RV and Motorhomes:

Question: What socket does it use?
Answer: Base socket: T10 921 922 912 194 168

Question: Will these work on all Motorhomes?
Answer: These LEDs are on a small paddle-shaped circuit board that slides into the socket like the bulb. Note that the LEDs are only on one side of the board, so the light will only project in one direction. In typical RV use, the light fixture projects light in only one direction anyway. These are 2-3 times wider than the regular 921 bulbs, same base just much brighter.

Question: Can these replace 918 bulb?
Answer: Yes, I replaced all light bulbs in my RV there were 921 and 906 bulbs. If 918 bulbs have the same size base, it should work fine These LEDs were much brighter and had significantly less current draw than the incandescent lights.

Question: Are these LED Bulbs easy to install?
Answer: Yes, just remove and replace with the other bulbs. Some of the old bulbs were a little tight and more difficult to remove, and some of these went in a bit snug, but overall very easy to replace, and they really make a difference.
