I installed them in my fogs 2 weeks ago. I have a 2017 Ram 2500 Laramie. I originally purchased the 9006 bulb type as these are what the OEM fog bulbs are. But the base of these LED 9006s were too large for the locking hole in the fog housing. So, I returned them and purchased the 9005s bulb type. They fit perfect. The 6000K white light matches the new DDM Tuning 35W 5500K Plus HID low beam kit I installed a week earlier. Light output is exceptional now. The low beam cutoff is perfect and does not blind oncoming traffic at any distance. The LEDs in the fog housing have a much wider and brighter broadcast of the white light. Not much blue out these LED lights. Just a pure white light. No flickering either. I'll report back if anything changes. But for now, the LED fogs and low beam HIDs were the best mods to date for my 2500.
