Fitting When you have demon eyes and you can't quite figure out how to mount them? Just bolt them on with demon eye brackets! Material: Made from a thick durable stainless steel sheet, then bent in a 6-ton metal brake, these demon eye brackets will probably outlast your headlights! 4.0 Foreground Limiter: The Mini D2S 4.0 option includes a foreground limiter! Our customer Robert explains it best: " Your eyes naturally tend to focus on the brightest objects so by limiting the bright light right in front of the car it helps your eyes to focus on objects in the distance". Hardware: In addition to just the metal brackets, these headlight mounts also include the screws, nuts, and custom carbon fiber spacers to get everything bolted up nice'n fresh. Just reference the pictures to see the sequence.
