Our Putco Anti-Flicker Harnesses for LED kits are designed to stop all the issues when upgrading your vehicle to an LED kit, The easy, no splice design simply plugs in between the LED kit and the OEM harness. This kit includes two resistors, and is able to be used on all import and domestic vehicles. Its compact design makes this wiring kit super easy to install with no cutting or splicing. Our kits prevent Flickering Issues, The flickering problem happens when your vehicle's computer notices that the bulb has been changed and is no longer the original bulb. It continuously sends a pulse to the lights trying to find the light bulb... many times that pulse of power gives a strobing or flashing effect to your lights. it also prevents the "Bulb Out light on the Dash" Newer cars have an indicator light to warn the driver if one of the headlights has burnt out. Since LED Kits run on a lower wattage than normal Halogen bulbs, your car thinks the bulb out. This will give you a "Bulb Out" indicator light in your dash. This usually does not affect the lights functioning but can be rather annoying while driving. Our Anti-Flicker Harnesses are guaranteed to fix these issues so you can upgrade your lights to a much brighter and more efficient technology without any issues.
