MicroGatling: The Micro Gatling Gun is the smallest version of the popular Gatling Gun design, made for use exclusively with the Morimoto Matchbox bi-xenon projectors, it should also work well on a variety of other OEM Fog Light projectors. In Comparison: Don't make the mistake of thinking all shrouds are created equal. Even though less expensive alternatives may be available elsewhere: Morimoto shrouds are made from the highest quality plastic and have by far the most durable metalized chrome finishes. The cheap-o's out there are flimsy enough to deform from the heat just a 35W HID bulb, and their chrome finish easily flakes off. LED Halos: Are a unique and effective way to further customize the look of your projector retrofit. The Profile Pivot (switchback) and Profile Prism (RGB) systems are easy to mount on the front of your shrouds, are reliable, and of course awesome looking. These shrouds feature DRL-Vents that will glow with light if you wanted to do something a bit different and mount the halos inside. Trimming: Please note that trimming shrouds is a common task when retrofitting. Whether required to clear part of the projector, or fit within the geometry of your headlight housing; it's normal. Luckily, they're made of plastic - making that easily possible. We recommend a Dremel hand tool with EZ Lock cutting wheels to make the job easy.
