I have a 2016 Ram 1500 Sport with factory installed LED packaging. The only non-LED lamps are the 3rd brake/truck light and the reversing lights. I replaced all non-LED bulbs with Luyed bulbs and have been very satisfied with no issues. However, as soon as I replaced the loading/bed lights, a warning appeared on the dash that the brake light was disabled. The headlights work and shine brightly, but the constant warning about them is annoying. All 3rd brake/truck bulbs - 921 bulbs. The 3rd brake light bulb fits snugly and firmly into the cartridge with no problems. But these 921 lamps are much weaker in cartridges. I don't know if this is a production issue and the base of these lights isn't that thick or anything. I've tried everything to make it more firmly in the socket, but the signal light is still on. After I replaced them with standard 921 bulbs, there were no more problems. Lued headlights were great before. I was definitely disappointed with their performance.
