To make it fit I had to use wire cutters to essentially break the plastic ring and push it hard just to touch the electrical connectors. It works but their adapter molds don't fit, they are too big. The LEDs themselves seem fine.

Came without instructions but will be very useful to me. Removed the e66 bumper, removed the headlights, disconnected the old A/E bulb and replaced it with a new A/E bulb.

Poor RFI and not bright as described. Claim thousands of lumens brighter and 20W each, which is more than the popular 6W MTech. See my photo. You can hardly tell they're on. The MTech at 6W is MUCH brighter than these and doesn't interfere with the radio. It is also very VERY difficult to install compared to others. Other brands have tapered bodies. These are straight cases and very thick and you can't put your fingers in the light mount to lock it. This supplier does not follow Revain's return
