In Comparison: Don't make the mistake of thinking all shrouds are created equal. Even though less expensive alternatives may be available elsewhere: our 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.
Mounting: Centric Rings are included by default when purchased along with compatible projectors to improve ease of installation on many projectors. The Centric Rings are simple reducers that clip into the of the shroud to reduce inside diameter, making them more of a "press fit" onto the lens holder of the projector. JB Quik Weld is also recommended in order to prevent the shrouds from vibrating loose over time.
LED Halos: Are a unique and effective way to further customize the look of your projector retrofit. The all new XSB LED (switchback) and XC LED (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.
