The BrightSource Chrysler/Dodge/Jeep Specific HID headlight bulb upgrades are designed specifically to improve the light output of the factory supplied H13 Bulb System. The BrightSource HID Kit powers a much whiter and brighter light output than stock headlight bulbs. The Daytime Running Light management issues have been completely eliminated with the BrightSource Opticoupler, a programmed and printed circuit board that deals with variable pulse circuitry that is delivered to the DRL. The DRL function switches from high beam to low beam, to avoid glare in traffic and improve safety. We also eliminated the function that turns the headlight out when the turn signal is on. The Opticoupler also eliminates flickering, light out issues and works with the OEM Vehicle "Auto" headlight function. The pre-assembled, plug and play harness makes for an easy installation. 6500 Lumens, 6000K colour output, 2500-hour bulb life. Digital Ballast, Two-Year Limited Warranty on Manufacturer's Defects.
