Review on 🔆 Auxbeam T20 7440 W21W LED Light Bulbs: Super Bright White 6000LM LED Bulbs for Front/ Rear Turn Signal, Blinker, Brake Tail, and Parking Lights by Marty Wainwright

Terrible. Installed 2011 Subaru Outback brake lights1.) They were dimmer than my standard bulb brake lights. Not impressed at all. 2.) One of the kits didn't work. (Yes I tried changing polarity) Auxbeam benefit gave a replacement 3.) I started flashing in less than a year. They blinked and flickered so much that people thought there was an ambulance outside when I pulled into the driveway. .) Really heavy in weight. When I got into a big hole, they flew out of the nest, and that seems really dangerous to me. Advantages. 1.) They light up faster than incandescent bulbs. But like all LED lights, I bought a pair of bulbs from the famous Sylvaina brand to try instead. They are much lighter and have a much higher heatsink to LED ratio.
