Review on 💡 NOVSIGHT H13/9008 LED Headlight Bulbs - 12000 Lumens, 300% Brighter Conversion Kits - 60W, IP68 Waterproof, 6500K Cool White - Fast Cooling Halogen Replacement by Jason Fanney

Installed in just 2 weeks and one has already stopped working. The headlights work 6 hours and my truck does NOT have daytime running lights. Updated 08/05/2021. I installed different LED bulbs and encountered the same problem. It turns out that a pin in the socket on the side of the truck has fallen off due to age. It was not easy to trace the problem. So I replace the socket on the truck wiring harness. Will be updated after replacement. Updated 08/11/2021. Both cartridges in the headlights exchanged. and no longer flicker. I also adjusted the position of the LEDs and now they illuminate the road evenly. now very happy with it.
