How to Install H11 LED Headlight Bulbs: Step-by-Step DIY Guide

Tired of your dull, dim stock incandescent headlight bulbs that barely illuminate the road?

Upgrade your car or truck’s lighting look instantly with H11 LED headlight bulbs from Underground Lighting.

There are tons of benefits to switching to the best H11 LED headlight bulbs, from brighter light output and more energy efficiency to durability and longer-lasting, innovative design.

Unlike older bulbs that shine light everywhere, LED bulbs project light exactly where you want and need it, resulting in “best in class” brightness.

When you’re ready to take the leap to H11 LED bulbs/HID bulbs, follow the steps below for an easy, breezy switch.

 

Tools and Materials Needed

    • You can either purchase these parts separately or buy an all-in-one conversion kit that contains everything you need, like the H11 Canbus LED Headlight Bulbs Kit from Underground Lighting.
    • Standard LED headlight conversion kits typically include: 
      •  
      • Your new LED bulbs
      •  
      • Heat diffusers
      •  
      • Fans
      •  
      • Current regulators
      •  
      • Error decoders
      •  
      • An instruction manual complete with all steps
      •  
    • When you purchase LED bulbs from Underground Lighting, you have the added benefit of “plug and play” installation, meaning you can get the job done in ten minutes or less, with no complicated wiring or slicing necessary.
    • UGL’s LED bulbs also feature built-in cooling fans and full metal heat sinking for in-house problem-solving that makes installation a snap.

 

Don’t skimp on safety! Be sure to take the following safety precautions before trading out your bulbs:
 

  • As with any electrical work, make sure you turn off the power to the light fixture you’re going to be working on before beginning.
  •  
  • You’ll also want to give the halogen lamps sufficient time to cool down to prevent heat-related hazards.
  •  
 

Step 1: Prepare Your Vehicle

 

Get ready for the installation by parking your car in a safe, well-lit area. This is for your safety as well as total visibility while doing the work.

Next, make sure you turn off the engine and remove the keys from your vehicle.
 

Now, it’s time to open the hood and locate the headlight assembly as the last step of your prep work.

 

Step 2: Remove the Old Bulbs

 

The first step involved in removing your old, dim bulbs is to disconnect the power connector from the back of the headlight.

Next, you’ll want to remove the dust cover (if applicable). If there is no dust cover, this step can be skipped.
 

Lastly, twist and remove the old H11 bulb from the socket. You’re done with the first part of the process!

 

Step 3: Install the New H11 LED Bulbs

 

Now that the old bulb is out, it’s time to compare the old bulb with the new H11 LED bulb you’re about to install.

Simply insert the new LED bulb into the socket.
 

Next, you’ll twist the new LED bulb in to secure it in place.

 

Step 4: Connect the Power

 

You’ve made the switch, but now it’s time to reconnect the power connector to the new bulb so you’re officially back in business.

Ensure all connections are secure and tight before considering the job complete.
 

Step 5: Test the New Bulbs

 

Time to put the product to the test! Turn on your car's headlights to test the new LED bulbs you’ve just installed.

Check the alignment and brightness to see if they meet your expectations.
 

Make any necessary adjustments before wrapping things up and hitting the road.

 

If the light doesn't turn on, try unplugging and flipping the plug 180 degrees. One side is positive, and the other is negative.

 

Step 6: Finalize Installation

 

Finally, you’ll reinstall the dust cover (if applicable). Again, if there is no dust cover to reinstall, you can proceed to the next step.

Close the hood of your car and get ready to enjoy brighter, better style and improved performance that comes with your upgraded LED bulbs.
 

Troubleshooting Tips

 

Although upgrading to LEDs is usually a seamless process, sometimes issues still occur.

Common issues you may encounter include compatibility issues like a buzzing sound, flickering, or error codes appearing on your dashboard.
 

If you’re experiencing flickering or inconsistent light output, check your vehicle’s connections and use a quality LED driver to get things back on track.

For buzzing or error codes, use the H11 HID Canbus Kit to prevent them in the future. The bulbs’ built-in CANBUS and silent cooling fan will also switch on when needed to prevent overheating, ensuring even heat distribution to avoid future issues.
 

If you’ve taken all of the above-listed steps but are still experiencing problems, don’t hesitate to reach out to the pros at Underground Lighting or your local auto shop for assistance.
