Review on Super Bright T10 921 922 912 LED Bulbs - Soft White Light for 12V RV Ceiling Dome Light - RV Interior Lighting for Trailer, Camper, Boat - 600 Lumens - Pack of 10 by Greg Greiner

I have a 13 year old Travel Lite Trail Cruiser. I ordered these bulbs to replace old gray incandescent bulbs. I intentionally replaced several lamps side by side in 2 lights individually. .The new bulbs are much brighter I need to replace the battery. He is weak. These bulbs were very bright when the battery was low, at least doubling the light output of the original bulbs. new LED bulbs. As in other posts, I recommend that you wiggle the bulb from side to side to make it easier to hit the light. Bulbs are approximately 1 1/2" long and 1/2" wide. 2 1/4" long x 1 1/2" wide. In all but one case they fit well in existing nests. The fixture above my stove was too small to properly fit the LED bulb. a lightbulb in the cooker lid, as the LED lamp is thin and flat. Since it doesn't generate heat, it doesn't bother me. A 2/3 open LED lamp in the oven socket emits more light than an old light bulb. and the installation of the entire luminaire took only a few minutes. I ordered a pack of 20 and everything works fine. I have an old truck and plan to try them with dome lights as well. Happy camper! Thanks very much!
