Review on 🌟 Enhanced Visibility: Pair of 2 Switchback LED Light Bulbs 3157 3057 3357 4157 with Projector for Standard Socket - White Yellow Amber Turn Signal, 22 SMD, Not CK by Oscar Ferrell

Trust me these are the flyback LEDs you need. I used two sets of equivalent bulbs from iBrightstar and both sets flickered yellow and then burned out completely. I thought maybe it was an electrical problem in my truck (or bad resistors) but the white one still worked fine (when the headlights came on). So I just wanted to go back to incandescent bulbs, but I found these and decided to give it a try - and they work great! No flickering on yellow or white. Very clean and very bright. In addition, amber has a pleasant, rich amber color - the amber of some other lamps is too yellow. This is an amazing product. Five stars! I wish I had found you sooner!
