Awsome 
 Bright enough, good product, great customer service. 
 Took a lil finageling to get it to fit,  but they do now n i love them,  super bright 
 So far so good. Used them as reverse light replacements for about two or three weeks. Not as bright as I'd hoped for but they are brighter than the factory bulbs. 
 Nice and bright, had them installed for about two months now. No issues 
 Very bright lights. I put these in as my reverse lights on my 2005 Silverado and am very impressed. These are very bright and project a nice beam onto the ground. I pull a trailer a lot and these are really nice for backing up at night. 
 Work great as a backup lamp in my 2015 Mustang 
 Very bright! These paired with LED headlights and illuminated together are brighter than the high beams alone! 
 More light than i expected, base may be a little larger than conventional bulbs and requires a little extra pushing to fit into socket.

Update, the whole led portion of the bulb fell off!  Had to take the light housing off truck to shake it out. 
 Product wakes as expected. Only issue I have is not with the bulbs, but the housing. If you have the housing that diffuses the light, the projector partYou  of this light won't be effective. Once again, not an issue with the light, just the user. 
 Great bulbs as always this is my second set from this company and they are decently bright for reverse lights on a 94 c1500 
 They work great for my s10 
 WORKED OK 
 Very happy with these as reverse lights. They illuminate everything behind my truck.  It's like having headlights on the back . Very good lights
