Installation - D1, D2, D3, D4 LED Headlight Bulbs Bypass the Original Ballast

Installing the LightingWay D-series LED headlights is easy? Specially if you want to upgrade without the original ballast from the HID Xenon bulbs to led bulb. It sounds complicate, but we can make it simple and easy!

1. Remove the headlight assembly out from your car.

2. Find the ballast and headlight.

Installation Process: Step 1 and 23. Remove the dust cover from the headlight housing to find the HID Bulb inside. Slowly rotate it, and you will feel the igniter fall off, then take it off.
Installation Process: Step 3

4. Press and open the clip and take out the original HID Xenon bulb.

  • Take off all wires from the ballast and install it in the same place. Why do we suggest keeping the ballast in the same place? Even though the ballast is unnecessary for the LED light bulbs, it can protect from dust and dirt. If you do not keep the ballast, there will be empty space that will attract dirt. So, keep the ballast in its original position but only connect the D-series LED bulbs to the light source.
  • Regarding the D1 and D3 LED bulbs, you probably need to create an extra female connector from the original power of light source if our plug doesn't match the female connector of the main power source. See the picture under below:
