7.How to installed the led headlight?
①.Led headlight kit installations start with preparation. You have to make sure the vehicle is off the battery is
off the battery is disconnected, and the engine is cooled down. This is will ensure your safety.
②Now we can move to the actual installation. If you have a single low beam kit, locate your low beam dust
cover on the back of your headlight assembly. Remove the cover by twisting it counter clock wise.This
should unscrew the dust cover giving you access to the bulb. Make sure you unplug the bulb from the wiring
harness before you attempt to remove it. Now you can continue to place the LED bulb in place of the halogen
bulb you just removed, just make sure you don't touch the glass part of the bulb. Customers can contact
with us for installation detail for any bulbs size like 9007/9004 80W installation with more complicated steps.
③. Installing the ballast/driver. First thing is to find a good location to place the ballast, somewhere close enough
to able to reach the bulb with the wiring plugs. Once you have the ballast secured then you can proceed to
plug the wiring to the bulb, and glug the old harness to the ballast.
