Review on 🚗 Highly Luminous T15 912 W16W LED Car Bulb Upgrade - 921 LED Bulbs with Advanced 3030 Chipsets, CANBUS Technology, 24-SMD, Ideal for Backup Reverse Lights - 6000K Xenon White (4pcs/Pack) by Max Guerrero

Of course I used for reversing lights. how often do you use the reverse lights? bright white LED was present. flicker-free for 90 days from installation. The size was huge but they are light and fit. The price was right. I received a set of 4 and assumed they had already burned out, but as of June 2021 they were still working fine. if we say that they are fog lights and work all day? I don't know what are your opening times? what about the reverse lights? Yes, they have 10x more candle power than my old reversing lights. I would keep old light bulbs in my tool box, you never know when those Chinese LEDs might hit you with a brick? but they work if you drive backwards!
