Why Replace Your Headlight Bulbs?

Driving with a burnt-out headlight is dangerous and illegal. Headlights are crucial for visibility at night and in poor weather conditions. Replacing a faulty bulb ensures your safety and that of other drivers. Plus, it helps you avoid a ticket for having a broken headlight.

When to Replace Your Headlight Bulbs

You should replace your headlight bulbs if:

  • The light is dim or flickering.
  • The bulb has burned out completely.
  • You notice one headlight is brighter than the other.

Tools and Materials Needed

Prior to starting, collect the required equipment and supplies:

  • Replacement headlight bulbs (Check your owner’s manual for the correct type. For the 2016 GMC Acadia, you need H11 for low beams and 9005 for high beams.)
  • A pair of gloves (to protect the bulbs from oils on your skin)
  • A screwdriver (depending on your vehicle, you may need this to remove the headlight housing)

Step-by-Step Guide to Replacing the Headlight Bulbs

Step 1: Purchase the Correct Bulbs

You need to buy the right type of bulbs for your 2016 GMC Acadia. The low beam requires an H11 bulb, and the high beam uses a 9005 bulb. These are available at auto parts stores or online. It’s always a good idea to buy high-quality bulbs for better performance and longevity.

Step 2: Prepare Your Vehicle

  1. After putting your automobile in park on a level area, turn off the engine.
  2. Locate the rear of the headlight assembly by opening the hood. The headlight assembly is behind the headlight lens.

Step 3: Remove the Old Bulb

  1. Access the Headlight Assembly: Depending on the side you’re working on, you may need to remove some components to get clear access to the headlight assembly. This might include removing the battery or the air filter box.
  2. Remove the Dust Cover: Some models have a dust cover protecting the bulb. To remove the lid, twist it counterclockwise.
  3. Disconnect the Bulb: Find the electrical connector at the back of the bulb. Gently press the tab and pull the connector off the bulb.
  4. Remove the Old Bulb: Twist the bulb counterclockwise and pull it out of the headlight housing.

Step 4: Install the New Bulb

  1. Handle with Care: Wear gloves when handling the new bulb. Oils from your skin can reduce the lifespan of the bulb.
  2. Insert the New Bulb: Align the tabs on the bulb with the slots in the headlight housing. To secure the bulb, insert it and twist clockwise.
  3. Reconnect the Electrical Connector: Attach the electrical connector to the back of the new bulb. Make sure it clicks into place.
  4. Replace the Dust Cover: If your model has a dust cover, twist it back into place.

Step 5: Test the New Bulb

  1. Turn on the Headlights: Before you close the hood, turn on the headlights to check that the new bulb is working.
  2. Adjust as Needed: If the headlight beam is not properly aligned, you may need to adjust it. Consult your owner’s manual for instructions on headlight adjustment.

Step 6: Repeat for the Other Side

If necessary, repeat the procedure with the other headlight. It’s a good idea to replace both bulbs at the same time, even if only one is out. This ensures consistent lighting and avoids having to repeat the process soon after.

Buying the Right Bulbs

When purchasing new bulbs, consider the following:

  • Brand: Opt for reputable brands like Philips, Sylvania, or GE.
  • Type: Ensure you’re buying H11 for low beams and 9005 for high beams.
  • Brightness: Check the lumen rating for brightness. Higher lumens mean brighter light.
  • Longevity: Look for bulbs with a long lifespan, especially if you do a lot of night driving.

Additional Tips for Headlight Maintenance

  1. Clean Your Headlights: Over time, headlights can become cloudy or dirty, reducing light output. Clean them regularly with a headlight cleaning kit.
  2. Check Alignment: Misaligned headlights can reduce visibility and blind other drivers. Check and adjust them if necessary.
  3. Replace in Pairs: Even if only one bulb is out, replace both to ensure even lighting.
