I have used these bulbs in my aging John Deere LA Series lawn mower headlights. Another type of LED I bought from Revain proved useless, but since these Makergroup 1383 1139 R12 RV LED reading lights' BA15S bayonet bases fit in the headlights, I decided to try them. They are beautiful and bright, completely closed and appear reliable. I bought these to replace those utterly, utterly, utterly useless lightbulbs that are wasting space/energy/dollars that are guaranteed to let you down. You can see them here. https://www. .amazon.com/gp/product/B07D839MG9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Avoid these lamps like the plague. These wonderful new Makergroup lamps have only been used for a few hours so I don't know how long they will last but so far I am absolutely delighted with them. The rest took minutes if they worked at all. So people selling these things should look at other uses like this on mowers. I was mowing our fields in central Texas at night. They work great! Based on my experiences so far, I'm really excited. Highly recommended!
