Headlight Restoration: Why Yellowed Headlights Are Dangerous

If you own a vehicle more than 3–5 years old, there's a good chance your headlights have started to yellow. This is more than cosmetic — it's a genuine safety concern.

Why Headlights Turn Yellow

Modern headlight lenses are made from polycarbonate plastic, which is susceptible to:

  • UV radiation — breaks down the lens surface
  • Oxidation — the plastic oxidises over time
  • Road debris — micro impacts create surface roughness

The Safety Risk

Studies show that severely degraded headlights can reduce illumination by up to 80%. This dramatically reduces your reaction time to road hazards.

Professional Headlight Restoration Process

1. Masking

We protect the surrounding paint.

2. Wet Sanding (Multi-Stage)

400 → 800 → 1500 → 2000 → 3000 grit progressively.

3. Machine Polishing

A cutting compound followed by finishing polish restores optical clarity.

4. UV Protective Coating

The most critical step — prevents re-oxidation for 2–4 years.

Without UV coating, headlights will re-oxidise within 3–6 months.

Don't compromise on visibility. Book your headlight restoration today.
