Upgrading Headlights on VW MK3 Golf for Better Visibility

Upgrading the Headlights on Your MK3 Volkswagen Golf

The Volkswagen Golf MK3 was produced from 1991 to 1998 and is still a popular choice among Volkswagen enthusiasts today. While the MK3 Golf has timeless style, upgrading the headlights is an easy way to modernize the look of your MK3 and improve visibility and safety while driving at night.

Reasons to Upgrade Your MK3 Golf Headlights

There are several benefits to upgrading the stock halogen headlights on your MK3 Golf:

• Better visibility at night - New headlights with updated projector beam technology can greatly improve nighttime illumination over the original halogen bulbs.
• Improved style - Aftermarket headlights come in cool Euro styles unavailable on US market MK3 Golfs. Upgraded headlights can modernize the look of your MK3.
• LED and HID options - Many aftermarket headlights allow you to install LED bulbs for a high-tech look or HID bulbs for brighter light output.
• Better safety - Being able to see more of the road at night is crucial for safely driving your MK3 Golf.

Aftermarket vs OEM Golf MK3 Headlights

When upgrading your MK3 Golf headlights you have two main options:

• Aftermarket Headlights - These are headlight assemblies made by companies other than VW. They often have updated projector optics and allow for LED or HID bulbs. Popular brands include Depo, Spyder, Spec-D, and Helix.
• OEM Headlights - OEM refers to headlights made by the original manufacturer, Volkswagen. These are often more expensive but are a direct fit with no modification needed.

Aftermarket headlights usually provide the best value for upgrading your MK3 Golf's style and performance. Many aftermarket headlights use projector beam technology that wasn't available when the MK3 was made in the 90's. This allows for clearer light output and the ability to use modern LED and HID bulb upgrades.

Popular Aftermarket Headlight Options

Here are some of the most popular aftermarket headlight options for upgrading MK3 Golf headlights:

• Depo Black Euro Headlights - A popular choice, with blacked out housing and projector optics. No bulb included.
• Spyder MK3 Golf LED Headlights - Come with integrated LED strips for a cool look. Plug and play installation.
• Spec-D MK3 Golf Projector Headlights - With a clear lens and projector low beam. Allows HID bulb upgrade.
• Helix MK3 Golf Crystal Headlights - Crystal clear lenses with blue accented projector housing.

There are many other options available from various manufacturers. Be sure to research reviews and confirm the correct fitment for your particular MK3 Golf before purchasing.

Adjusting and Aiming Aftermarket Headlights

Once installed, your new aftermarket headlights may need some adjustment to get them aimed properly. Here's how to adjust MK3 Golf headlights:

Vertical Aim Adjustment

There are adjusting screws at the top and bottom of the headlight housing to adjust vertical aim. Turn these with a Philips screwdriver to pivot the beam up or down.

Horizontal Aim Adjustment

The horizontal aim is adjusted by loosening the headlight mounting bolts and pivoting the entire assembly left or right as needed before retightening the bolts.

Headlight Aiming Tips

• Perform adjustments at night with the headlights on and someone observing from the front of the car.
• Make small incremental adjustments and reassess.
• Refer to a VW repair manual for detailed aiming procedures.
• Consider having a professional shop perform final aiming if you can't get the beam aligned properly.

Adding LED or HID Bulbs

One advantage of upgrading to aftermarket MK3 Golf headlights is the ability to install high-performance LED or HID bulbs for increased light output. Here are some tips for adding these bulbs:

• Make sure your new headlight housing is designed for LED or HID bulbs. Look for "HID Ready" or similar wording.
• Choose good quality bulbs from reputable brands for best performance.
• You may need to install bulb adapters to adapt the new bulbs to the MK3 Golf's wiring.
• HID kits include bulbs and ballasts. Follow all wiring instructions carefully.
• LED bulbs are plug and play, but heat management is important.
• Adjust your aim after installing new bulbs!
