I just purchased a used travel trailer, 2010 Heartland, one of the bulbs in a light was burned out. I noticed that when the lights were on how hot the bulbs/light got. I looked and found these bulbs with a good review, reasonable price and 20 pcs (enough to replace all my bulbs.) They fit and replaced the 1141 bulbs I had, no problems there. I was totally amazed at how much more light these put out, and the warm bright light lit up my camper perfectly. I had the lights on for over an hour, I turned them on and off several times, instant on response and they were cool to the touch. The only reason I am giving 4 stars is, don't know how long they will last. Update in the future. So far great product, Thank you.
