Great LED license plate lights
Really cool , put them on my 2022 Silverado Z71 for the license plate lights . Love the bright red color . Very easy to install and I’m very satisfied with them . Very bright and adds a little flair to my truck , something a little different . No error sent to the dash and they work exactly like advertised . Very happy !! Photos are basically the same just showing left and right .

Awesome lights
Like always another great buy from Yorkim. Have installed these in every vehicle I have owned since 2016. Always works well and lasts forever. Will keep buying them. Very bright and fits perfectly. No error codes and does not stay lit when off like some others do. Simply unplug old bulb and install these.

Much nicer and brighter than this little stock halogen lights
Been working great now you can definitely see my indicator lights a few of the old bulbs burnt out these are much brighter and a little nicer plus was able to use them on some interior lights around the footwell as well to brighten up the inside when the doors open.

this 10-pack of 3157 automotive LED backup/reverse light bulbs is a great deal
This 10-pack of 3157 automotive LED backup/reverse light bulbs is a great deal, and they can work for a variety of other bulb sockets like 3056, 3156, 3156A, 3057, 4057, 3157, 4157, and T25. These LED bulbs are noticeably whiter and brighter than standard bulbs, and are truly plug and play under most circumstances. A great upgrade!

2014 Mazda3 - hyper flashing when installed
Purchased for a 2014 Mazda3 but resulted in hyper flashing when using the signal lights. It’s fine when using the hazards. Maybe they require resistors? Too bad because they light up instantaneously and are solid bright.

Bright and fit great
Got these for my 2020 Chevy Colorado. They are plenty bright even with my tinted tail lights. The fit was great, and the price was good too. No flickering that I’ve noticed, they seem to be cool, they don’t get hot. I have resistors so no error codes but if you don’t have them they might show an error code or blink real fast. Will buy again

ルームランプに最適かな
個人的にこの明るさと色はナンバー灯やポジション灯より、室内灯としてドレスアップするのにおすすめです。 ポジションにしては暗く、ナンバー灯も薄青暗くカッコいいとはなかなか思えません。
