I've been underwhelmed by my 2016 Ram 2500's stock halogen projector headlights since my truck was new. They were adequate, but nothing more. However, I didn't want to deal with CANBUS issues or stuffing an additional CANBUS decoder in my housing, and certainly didn't want to have to cut a hole in the dust cover to get something to fit. I saw a FB post about the Lasfit LCair bulbs and decided to give them a try because there was a Black Friday sale going on. Installed them tonight (Hi/Low/Fog) and was blown away at how much better they made my stock headlights. I initially set them at a very conservative angle, but once I got them adjusted to my liking, they're perfect. No CANBUS errors or flickering, and everything fit underneath the stock dust cover. I can't ask for a better product...highly recommended!
