Introduction: How to Convert Your Headlight Bulbs to LED
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. The kit I used features CREE LED bulbs that have an output of 3,200 lumens. Typically, factory halogen bulbs have an output of just 1,000 lumens.
Step 1: Find Your Headlight Bulb Type
The easiest way to find your headlight bulb type is to search for it in the Sylvania online database.
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
If your vehicle is not listed on the Sylvania site you could try these other methods to find your bulb type:
- Check your vehicle owner's manual
- Contact the vehicle manufacturer via your local dealer
- Remove a headlight bulb and read the bulb information
*Make note of your bulb type*
Step 2: Purchase an LED Conversion Kit
Now that you know your bulb type you need to purchase an LED headlight conversion kit. A variety of online stores sell these. The kit I used for this instructable is a CREE LED type that was purchased from MotorFiend.com for $119 including shipping.
Step 3: Unboxing Your LED Conversion Kit
Once you receive your LED headlight kit check that you have all the correct components. There should be two LED bulbs, two ballasts and wiring.
Step 4: Take Some Photos
Take some photos of your halogen headlights before you install the LED headlights, so you can compare the difference later
Step 5: Locate Your Headlight Bulbs
First ensure your vehicle is secured. Engine off, keys removed from ignition, parking brake on.
Pop the hood and locate your headlight bulbs
Unplug the plastic wiring connector from the bulb.
Tip: If you haven't ever replaced a headlight bulb the plastic clip might need some gentle assistance with a flat screw driver.
Step 6: Remove Your Halogen Bulbs
Depending on the bulb type you may need to remove a metal clip first, then you simply twist anti-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 Bulbs
Install the LED bulbs into the headlight socket while being careful not to touch the LED with your bare fingers
Gently twist the bulb in a clockwise direction to secure it
Step 8: Connect the LED Ballast
Connect the LED ballast wiring. One end goes to the new bulb, the other to the original wiring harness.
Step 9: Check the Cut Off
Power up your headlights and check the position of the cut off.
You don't want to be blinding other drivers with you 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
Step 10: Secure the Ballasts
Secure the ballasts using either double sided tape or plastic zip ties
Tip: You want to keep the ballasts away from excessive heat, vibration and moisture. I mounted mine on the back of the headlight housing
Step 11: Test Drive
Time to test out your new LED Headlights!
