SIERRA WIRING: A special Sierra Spec HD Relay Harness is designed to make your headlight retrofit a piece of cake. Double-sealed 40A relays and 14-gauge stranded copper wire wrapped in durable black tech-flex mesh are completely new features that ensure the wire harness meets and exceeds the looks and quality of the factory parts it’s replacing. No cutting, no splicing, no mess, and no stress. There are only five connections, and each of them is plug-n-play. Most importantly, the harness includes the proper capacitor to absorb and smooth out the pulsed signal from the factory headlight circuit that plagues these trucks.
POWERFUL BALLASTS: Morimoto may be known first and foremost for developing the aftermarket’s best HID bulbs, but they’ve also changed the game when it comes to ballasts. The all-new XB ballasts included in this HID kit offer the perfect blend of function and style with an industrial-edge design and state-of-the-art technology. Morimoto moved the igniters closer to the HID bulb to mimic OEM and further away from the circuitry to reduce EMI/RFI radio interference and eliminate failures and misfires. We’ve sold thousands of these and use them in our own vehicles. User approved!
FULLY BACKED: At The Retrofit Source Inc., we don’t carry products we aren’t confident enough to back with a full 5-year warranty on all components.* The Morimoto Elite 2015/2014 GMC headlight upgrade kit is designed to run for 2,500 hours, so that’s what the guarantee covers. Even better, we’re always available to offer expert assistance and advice to help you through any technical difficulties you are experiencing. We’ve seen some pretty crazy promises being made by other online dealers. A “lifetime” warranty on a product with a finite service life, really? Just remember if it’s too good to be true, it probably is. [*XB55 kits have a 3-year warranty]
