Review on GRV Ba15s 1156 1141 LED Bulb 4W 56-2835SMD Super Bright - RV Trailer Camper Motorhome Interior Lights - Cool White Pack of 6 by Jack Collins

Prepare to order a few more of these, there's nothing better. The best upgrade I have ever made to my 5 wheel camper. I hate the old yellow lightbulbs and I just missed the light from them. Replacing them all with these LEDs was quick and easy (the non-polarity in particular was a bonus) and now I have more light, less heat and less power consumption. There are no downsides other than the cost of the initial investment, but still I expect them to last MUCH longer than standard bulbs.
