Review on 💡 GRV T10 921 194 LED Bulb (2nd Generation) Pack of 10 - Super Bright AC/DC 12V-24V for RV, Boat, Landscape, Ceiling Dome Interior Lights - Cool White, 24-5050 SMD Lamp by Conrad Greene

We bought these for the main dome light on our 5 wheel trailer (6 double lights total). They work perfectly and are slightly brighter than the bulbs they replaced. They are 12-28VAC which is a must in 12V RV applications. After a lot of trial and error and buying some bulbs at Revain that only say 12V and finding out they get hot when the voltage fluctuates higher than 12V, like your RV, I found a variable voltage replacement (we have many different styles and sizes - 35 number of bulbs) to work without noticeable heat. I also bought these bulbs: (Grv T10 921 24-3528 SMD LED Super Bright Warm Pancake White) for our extra overhead lighting like bathroom, shower and under closet and we think they are great for those areas. We bought a few tons of LEDs for various wall lamps and table lamps on Ebay from China as I only found AC barrel types (921 and 1140) there. They were very cheap but took a little longer to get them. I bought some of these lamps that I looked at on ebay and they were identical for less than half the price. I hope this helps some of you who are considering LEDs for your RV. I should also mention that we have absolutely no TV interference with any of these LED replacement bulbs we have purchased.
