Review on H4 9003 HB2 LED Headlight Bulbs - 2020 Newest Super Bright 12000 Lumens 80W, 6000K Cool White 360 Degree Emitting Hi/Lo Beam Fog Light Replacement For Halogen by Scott Reeves

I had issues with these lights from the start. Thankfully, before going through the hassle of removing the grille, headlights and radiator dust cover, I tested the headlights by connecting them to an external power source. The first light worked as described for a solid four seconds before turning off and never coming back on again, so far so not all that good. Additionally, while testing the second light, it began to flicker after about 45-50 seconds, then shutting off, coming back on again and then ultimately ending up with two of the four diodes failing completely, leaving only one side of that 2nd bulb functioning properly. So I’m left with 1/4 of the product working.Not sure if this was a shipping issue, poor packaging, inferior quality control or just dumb luck. Either way, that was my experience. I wish it would have been similar to those who had a flawless install and gave this product five star reviews.Hopefully someone from customer service will get back to me to remedy the issues. If they do and their product works, I’ll adjust the review accordingly.
