Step by Step Guide: How to Install Headlight or Fog Light LED Conversion Kit

All vehicles fitted with halogen headlight bulbs from the factory are suitable for LED conversion. The main advantage is a massive increase in road illumination and therefore improved safety when driving at night. 

We offer three series of LED performance bulb: L1, T1, and X1 Series. The LED  bulbs we offer are "plug-n-play," with bulb mounting collars that are designed to fit into the same socket and mate with the same wiring connector(s) as your original halogen ones. Installation is easy - however, the relatively larger size of the T1 and X1 Series bulb base may take up more room inside your headlamp assembly. The L1 Series with the aluminum fin cooling system has better fitment due to its unique heat sink design. We recommend using L1 Series in the application with very tight space or with plastic dust caps. 

This guide will walk you through the steps on how to install a LED Conversion Kit. 

STEP 1: Find The Bulb Type of Your Headlight or Fog Light

Your car or truck is equipped from the factory with a specific bulb size/type, using an industry-agreed standard for identification. These sizes are universal throughout the auto industry, with a specific code number for each bulb type. 

Use our  Bulb Look Up Tool to find the right bulbs for your car. As a precaution, we recommend verifying the headlight bulb size for your vehicle by checking the owner's manual. 

The two possible results are as follows:

  1. Single Beam Bulb - the high and low beams use two separate bulbs
  2. Dual Beam Bulb - the high and low beams are combined in one bulb
STEP 2: Select The Right LED Bulbs Best Fit Your Needs
For LED headlight bulbs of standard brightness, specially developed copper and aluminum "heat sinks" allow heat to radiate away from the bulb. The heat sink metal material may be shaped into flexible braided ribbons, or into rigid fins arranged in a radial pattern. When we use the term "standard brightness", we're referring to the level of luminosity output produced by most LED headlight bulbs. This brightness, it should be noted, is more intense than what's produced by just about any halogen headlight bulb.
In cases of LED bulbs with higher output, small cooling fans built into the base of the lighting assembly draw air over built-in heat sinks and out through specially placed vents. Technology has also allowed the creation of fans that cool effectively while drawing less energy than previous ones - lasting an equal or greater duration than the bulb itself.

STEP 3: Select The Necessary Wire Harness

You may need an extra harness to solve the various issues caused by the CanBus or PWM system in newer vehicles. Please check here for a simple guide to Select the Correct Harness for LED Light Conversion . 

STEP 4: Locate And Remove The Halogen Bulb

Due to limited underhood space, some modern vehicles require removal of the entire headlight assembly for a simple headlight bulb change. And on some others, taking the headlight assembly out means the front bumper cover must be unbolted and moved forward for clearance. Please find the steps of How to Access and Change the Bulbs on Your Vehicles

General Steps:

  • First, ensure your vehicle is secured. Engine off, keys removed from the ignition, parking brake on.
  • Pop the hood and locate your headlight bulbs.
  • Unplug the plastic wiring connector from the bulb. 
  • Depending on the bulb type you may need to remove a metal clip first, then you simply twist counter-clockwise and pull out the bulb.

Tip: Store your halogen bulbs in a safe spot. You may want them in the future.

STEP 7: Install The LED Bulb

  • Install the LED bulbs into the headlight socket while being careful not to touch the LED with your bare fingers. 
  • Optional: 
  • Optional: If any extra harness is required, please connect the harnesses with the LED bulb drivers, before connect to the headlight harness. 
  • Optional: Dust cover:?????????????????
  • Secure the LED Drivers and the other applicable harness using either double-sided tape or plastic zip ties.
  • Optional: Put the dust cover on if any.

Caution: 

  • Be careful not to damage the bulb power wire.
  • When adjusting the bulb base, be careful not to wipe off the thermal paste because this can negatively influence heat dissipation.
  • Do not press the center of the fan by force. It will damage the bearing of the fan.
  • Please avoid installing the X1 Series Bulb in applications exposed to excessive amount of elements. Do not use it to convert Fog Lights. 

Most of LED Headlight Conversions are as easy as replacing your stock bulb. Only 10% of the applications involves in the optional steps. We prepared some toughest cases of LED conversion to show you every possible step involved.

Tip: You want to keep the LED driver away from excessive heat, vibration, and moisture.

STEP 8: Adjust the Headlight Aiming

Power up your headlights and test your LED lights. Check the aiming of your headlights. You don't want to be blinding other drivers with your bright new lights, so you may need to adjust the position of the headlights. You can do this by adjusting the headlight alignment screws. Check your owner's manual for more information on how to adjust the aiming of your headlight. We have prepared the basic steps on How to Adjust Your Headlights for Perfect Aiming for your reference.
