These work great! I bought a set that are 3157 style for the bulb socket, THEY DID NOT WORK. This 7444 / 7440 style fit great and are super bright for the reverse / back-up lights. Super easy to install. I would add the suggestion to remove the taillight and see what existing bulb type you have and then pick put the style you need.

I already had a couple of led bulbs in my read turn lights and were working really well so I decided to go with leds for the front turn lights.After some research I picked these as I was already using a pair of white bulbs for the bakc up lights and the fact these were supposed to have the circuitry to prevent cambus issues.That was not the case and my car is old is a 2011 Nissan so is not a high sensitivity electronic circuit.I installed just one to test and it worked fine for a few seconds but noticed some glitches. Then istalled the second one and it went crazy with the blinking rate so I ended up keeping the original bulbs until I find some others that don't trigger the burnt light behavior.For what is worth, they came with a set of resistors but I don't want to use those. I preffer to have the wiring as standard as possible.

sealight, 7443 led white. they work, but not as I had wanted. for my 2015 Chevy Silverado, they hyper flash and I get the bulb out warning in the driver information center. as the wiring on most modern vehicles isn't very good quality to start with, I really ave no desire to cut into the harness to install the modules that is supposed to prevent this problem. I bought Sealight LED headlights for the same Vehicle a couple of years ago and have had no problems with them. bought these bulbs not necessarily looking for brighter or longer life over the factory, but to have a lower operational temperature. the factory bulbs after they have been on for a while, like if you're sitting still in traffic with your foot on the brake, have a temperature approaching about 500°+f. that heat is what kills the sockets. other than the hyper flash problem, they fit and work good. I need a total of 8 bulbs and as I said I am not willing to hack in to the wiring harness to install modules to prevent hyper flashing. at $10.00+ per bulb, I was hoping for more.

ハイエーススーパーロングのバックランプには購入しました。かなり明るいです。良い商品だと思います。

根本が黒色なので、気になりましたが、付けてみると、黒色部分までソケットに入るので、シルバー部分しか外に出ません。明るいです。バックする時、安心です。

初めて取り付けました。作業は簡単で(車種による)10分程度で完了。夜になりバックしてみると驚きの明るさでした。メーカーに最初からこれにしてって言いたいです。

気に入った点・純正バックランプと比べるとめっちゃ明るく、車体より後方への照射範囲が広がり、後方確認が格段に向上した。気になる点・車体より後方への照射範囲は広がったが、車体より50cm以内の後方照射は向上していないため、壁際の停止はイマイチである。ナンバー灯のバルブを変更すれば補なわれるのだろうか不明である。
