Review on 🚘 Enhanced BMW Xenon White LED Angel Eye Halo Ring Marker Light Bulb: High Power 6000K, 20W/40W, CREE Technology - Fits E39, E53, E60, E61, E63, E65, E66, E83, E87, X5 (2x) by King Reeves

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 policy and also asks you to pay for shipping back to Hong Kong. They refunded me $20 and let me keep them, which is probably what I would have kept if I had actually sent them back and had to pay for shipping.
