Review on 💡 Combriller 912 921 LED Bulb: Super Bright 3600 Lumens Backup Reverse Light Bulbs for Pickup Trucks and Cargo Lights, Canbus Error Free by Mike Lunde

The fit and finish of these 912/921 bulbs is well done. I used them to replace an old 912 lightbulb in my truck's engine bay. The lamp has been replaced, so keep that in mind if you're working in tight spaces. Not surprisingly, they are brighter and have a fairly cool white light of at least 6500K. Note that they are whiter. The new headlights don't have polarity issues like some of the earlier LEDs, so wire them however you want. My truck's engine bay is diesel so it's pretty warm in there - we'll see how well these bulbs hold up. The lightbulb worked fine. Let's see if the LEDs do it. Most of my other LEDs are generally stored at cooler temperatures - at least less extreme ones. Pretty good so far.
