Review on XtremeVision 2011 2016 Premium Interior Installation Lights & Lighting Accessories by Dave Hammon

2013 BMW M5 - All Items Received. However, the bulbs installed in the headlights are slightly larger in diameter than the original glass bulbs, which causes some difficulties (strength) during installation. Some users may need to modify the case to make it slightly larger to accommodate the new LED bulbs. The BMW connectors only touch at the extreme ends. These terminals are obviously metal, carry little voltage and are designed to make contact with the lamp's terminals. Not all lamp connectors are the same length and one of the LED bulbs was not used at all as the connectors (wire) were too short and did not make contact with the BMW lamp connectors. Luckily I had a spare bulb from another project and avoided the problem. It would have been better if a few extra lamps were included in the kit. Basically I am satisfied with the product. Big upgrade to original bulbs. The atmosphere is incredible. Cool bright light with a bluish cast. Update 11/23/2017 The LEDs still work and are installed in the 2013 M5 F10. However, they started to flicker shortly after installation. I don't think the bulbs are bad, but it is the BMW F10's complex electrical system. Through a little research, I learned that the system constantly monitors the current going to the bulbs. Because the bulbs use less power than the original bulbs, they flicker. For this reason I am looking for another LED solution. There are alternatives that do not guarantee flickering, but for the same amount they are 6 times more expensive.
