Review on HOTSYSTEM LED Light Bulbs 1156 1141 7506 P21W BA15S 18-5050SMD For Car RV SUV Camper Trailer Trunk Interior Reversing Backup Tail Turn Signal Corner Parking Side Marker Lights(WarmWhite,Pack Of 10) by Raysean Forth

I bought some of these for my camper trailer. I got the warm white color and I couldn't be happier. I just installed them tonight in my trailer and the color is almost a perfect match to the older, power hungry incandescent bulbs. The brightness is just a hint less bright than the 1141 bulbs they replaced, and the color is just a slight bit "cooler". Not bad at all. These only use about 1/6th the electricity of the old bulbs, and they perform almost identically. I am so happy that I just bought 20 more! Batteries should last much longer now. Happy Camping!Update: I just tested the amperage on this bulb. The bulb starts out at 0.183 amps cold and rises to 0.195 amps as it warms up. At my battery voltage of 12.8 volts that works out to 2.496 watts once warm. In other words, 7 of these bulbs use the same amount of electricity as one incandescent 1141 bulb. Now I can light up my trailer like a Christmas tree, and I don't have to worry about running down the batteries. Worth every penny!
