9005/9006 Daytime Running Lamp Adapter

Is your vehicle outfitted with Daytime Running Lamps? No problem – this adapter plugs in between the stock headlight connector and our relay harness, preserving the functionality of the DRLs. Only one is required for the HRK6 kit.

Headlight Relay Kit Extensions

In some vehicles, the battery is in a location at which the harness will not reach both it and the headlights. In these cases, a Headlight Relay Kit Extension is required. These extensions are designed to plug directly into the harness of either the HRK1 or HRK2 to extend the main power lead. No special tools are required to install them.

Each kit includes a pre-assembled extension covered in split braided tubing as well as cable ties for an absolutely neat installation.

    Awesome harness, the quality is second to none. Installed on my 1999 Suburban with Spyder glass lens headlights. CE Auto Electric Supply has been my go to for more and more stuff over the years. Tony and his staff provide great customer service and have fast shipping!

    Thank you for the super fast shipping of your quality product. I’ve replaced many headlight switches in my 98 Tahoe being that the switch takes the full load of all the lights and overheats, killing the lights until the switch cools. My harness looked OEM and the plug and play install was very easy with excellent color instructions. After installing the dual relay harness my headlight switch runs dead cold, plus I am able to run 100 watt high beam and 80 watt low beam bulbs! Awesome! I’m recommending to all my buddies.
