Daytime Running Light Flickering After HID Kit Installation...

Here you will find possible solutions for issues with your Daytime Running Light after installation of an HID Conversion Kit. Typically HID Kits work properly with vehicle's with Daytime Running Lights however there are some makes and models that use extremely low voltage for the DRL setting and this voltage is NOT enough to keep the HID Kit running. In these cases it typically requires the deactivation of the DRL feature in order to install and use an HID Kit. This goes with ALL HID Kits.
