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 Brian Buck

I recieved fast delivery in the product. It was shipped in a plastic bag with no padding which concerned me. So far the bulbs I'm using work. The brightness of the bulbs what not what I expected comparing them to the existing bulbs that came with the camper. They produce half lumens as the original bulbs. The good thing is they produce no heat. The original bulbs will burn you. I don't think I would buy this again and next time focus on the lumens in other bulbs.
