Review on SEALIGHT H11/H8/H9 LED Bulbs: 18000 Lumens, 600% Brighter Low-Beam LED Replacement, 6000K Daylight White, Hassle-Free Installation - Pack Of 2 by Leo Black

I've got a few others of these lights in other vehicles. So far they work well.I've had HID's in this car in the past and they included separate gromets and plugs which made install of the ballast easier.However, in this install for this car, there wasn't a great solution. My headlight housings only have so much room in them. The bulb itself fits, but no place to mount the regulator, and it doesn't disconnect from the bulb so you cant run the cable through the dust cover.Something that seems hard to come by is the physical size dimensions of the backside of the bulb, the heatsink. For future reference, the mounting surface to the back of the heatsink is .82" and diameter is 1.5"Overall, they're not a bad bulb. But, pay attention to how you're going to install.
