Panamera-LED: takes the original Panamera shrouds to an all new level of OEM plus! With a Type II White/Amber Switchback LED circuit built into the backside of the shroud that illuminates the four lenses on each corner, these are undoubtedly the most baller status shrouds we've ever offered. With excellent coverage for most projectors too, they're also very functional. In Comparison: Don't make the mistake of thinking all shrouds are created equal. Even though less expensive alternatives may be available elsewhere: Morimoto Panamera LED's use an XSB Switchback driver and high quality LED PCB in place of the cheap crap found in the generics. Their shrouds are made from the highest quality plastic and have by far the most durable metalized chrome finishes. The cheapo's out there are flimsy enough to deform from the heat just a 35W HID bulb, and their chrome finish easily flakes off. A or B: At our shop, we're also meticulous with quality control. If a shroud has a minor factory defect; we sell it at a discount as a "B stock" unit - which is perfect for budget retrofits or when painting them is part of the plans. If you won't settle for anything less than perfect and plan to leave them chrome; go for the "A Stock" Shrouds. Mounting: Centric Rings are not included by default, but are highly recommended to improve ease of installation on many projectors. The Centric Rings are simple reducers that clip into the shroud to reduce the 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 Profile Pivot (switchback) and Profile Pixel (RGB) systems are easy to mount on the front of your shrouds, are reliable, and of course awesome looking. To determine which size is best for you - check out the size-guide in the images above. 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.
