Review on 💡 Ultra-Bright 4-Pack Xenon White LED Bulbs | 921 912 922 T15 W16W | 6000K 1000 Lumens | Error-Free Canbus | Backup Reverse Parking Lights Side Marker Light | 12V-18V by Steven Notsinneh

I use these as the backup and bedside lights in my 2013 Ford F-150. They are much brighter than traditional incandescent bulbs. These LEDs make it easier for me to see at night. I have no problems with it at all, the truck doesn't give any warnings. They are easy to replace with incandescent bulbs. The hardest part is just accessing the old lightbulbs to replace them. I had a problem with a lightbulb after about a year. He started blinking. I contacted the seller and he sent me a replacement. It would be nice if nobody came out so quickly, but at least there were no problems with the replacement. Got a second one and the seller didn't send a replacement even though I bought 4 packs and they only replaced one bulb. For the price they don't last long enough. They are good while they work, but not good enough.
