How to Restore Clarity to Foggy, Oxidized Truck Headlight Lenses

How to Restore Clarity to Foggy, Oxidized Truck Headlight Lenses

How to choose the right headlight bulbs for your truck?

Choosing new headlight bulbs for your truck can be confusing with all the different types available today. Here are some tips to help you select the right replacement bulbs:

1. Check your owner's manual

Your owner's manual will indicate the bulb type, size, and wattage recommended by the manufacturer. Using this information ensures you get bulbs that are compatible with your truck's electrical system and headlight housing.

2. Understand bulb types

  • Halogen bulbs - inexpensive, common option providing white light
  • HID (xenon) bulbs - produce brighter bluish light, more expensive
  • LED bulbs - long-lasting, energy efficient, can have high upfront cost

3. Consider light temperature

Light temperature, measured in kelvins (K), affects the color of the light. Cooler light around 5000K appears whiter, while warmer light around 3000K looks more yellow. Aim for bulbs in the 4000-4500K range for optimal visibility.

4. Check bulb size

Bulb sizes are standardized. Common sizes for trucks include H13, 9005, 9006, etc. Consult your manual or existing bulbs to find the correct replacement size.

5. Don't overlook wattage

Higher wattage bulbs produce brighter light, but don't exceed your truck's recommended wattage to avoid problems. Lower wattage bulbs may not provide adequate visibility.

Taking the time to find the right headlight bulbs for your truck improves safety and visibility on the road. Following the tips above will ensure you choose compatible, high-quality bulbs tailored to your needs.

How to Install Aftermarket Projector Headlights?

Upgrading to projector headlights can make a huge difference in illumination and style for your truck. While professional installation is recommended, you can install aftermarket projector headlights yourself if you're handy.

What You'll Need

  • New projector headlights designed for your truck
  • Basic hand tools - wrenches, screwdrivers, pliers, etc.
  • Electrical tape
  • Dielectric grease

Steps to Install

  1. Disconnect the battery to avoid electrical shorts.
  2. Remove stock headlight housing. This usually involves unscrewing a few bolts and unplugging the wiring harness.
  3. Inspect wiring harness. Look for cracks, bare wires, corrosion. Repair or replace if needed.
  4. Plug harness into projector headlights. Apply dielectric grease to prevent corrosion.
  5. Mount new headlights using bolts. Check alignment and adjust if necessary.
  6. Secure all wiring with tape to prevent rattles and shorts.
  7. Reconnect battery and test lights.

Alignment Tips

Proper alignment maximizes visibility and prevents blinding other drivers. Follow your truck's guidelines, but generally you want:

  • 1-2% upward aim on low beams
  • Horizontal aim with slight rightward adjustment
  • 2.5-4% leftward and downward aim for high beams

Adjust gradually, testing adjustments at 25 feet from a wall or garage door. Projector lenses give very precise aim control.

With some automotive know-how and patience, you can upgrade your truck with custom projector headlights. Drive safely with improved lighting!

How to Adjust the Beam on New Headlight Projectors?

Installing new projector headlights can significantly improve visibility, but only if properly aimed. Follow these steps to adjust the beam on new headlight projectors:

Materials Needed

  • Phillips screwdriver
  • Flathead screwdriver
  • Measuring tape

1. Park on Level Ground

Park your truck on flat, level ground 25 feet away from a garage door or solid wall. This gives you a consistent reference surface.

2. Locate Adjustment Screws

Projector lenses have adjustment screws that control vertical and horizontal aim:

  • Vertical - up/down beam cutoff
  • Horizontal - left/right aim

3. Adjust Low Beams

For optimal low beam aim, turn screws to point cutoff 1-2% upward and slightly rightward.

4. Adjust High Beams

Aim high beams 2.5-4% downward and leftward to avoid blinding oncoming drivers.

5. Test and Re-Adjust

Make small adjustments then retest beam pattern. Iteratively adjust until you achieve ideal aim.

With some trial and error, you can dial in perfect beam alignment for your new projector headlights. Drive safely with improved visibility!

How to Clean Foggy and Oxidized Headlight Lenses?

Over time, headlight lenses can become foggy, yellowed, and oxidized, reducing light output. Here are some tips for restoring clarity to your headlights.

Supplies Needed

  • Sandpaper - 400, 800, 1500, 2000 grit
  • Rubbing compound
  • Plastic polish/wax
  • Microfiber cloths
  • Masking tape
  • Newspaper
  • Latex gloves


  1. Clean lenses thoroughly and mask off with tape.
  2. Wet sand lenses in a circular motion with 400 grit. Continue with 800, 1500, and 2000.
  3. Rub a thin coat of compound using a damp cloth. Buff off residue.
  4. Polish lenses using a lint-free cloth. Apply plastic wax for added protection.
  5. Remove tape and admire your like-new headlights!

Be sure to work methodically and reapply wax every few months. With some elbow grease, you can restore clarity and safe visibility.

Caution: Oversanding can damage the lens. Test first in an inconspicuous spot if unsure.
