Headlight Restoration in Hackbridge | KITH Bodyworks & Accident Repair Centre

Modern headlight lenses are made from polycarbonate plastic, not glass. Polycarbonate is lighter and more impact resistant than glass, but it degrades under UV radiation. The outer surface oxidises progressively, yellowing and becoming opaque. A headlight that used to cast a clear, wide beam now casts a dull, yellow, narrow one. The vehicle looks older than it is and the driving experience at night is measurably worse. At KITH Bodyworks in Hackbridge, headlight restoration is typically completed the same day.

The restoration process removes the oxidised surface layer mechanically. We work through progressively finer grades of wet abrasive paper, removing the cloudy outer layer in stages. After the final abrasive stage, the lens is machine polished with a compound designed for polycarbonate. The result at this point is optical clarity close to what the lens had when new.

The UV sealant stage is where many cheaper restoration services cut corners. A freshly polished polycarbonate surface with no protection will start to re-oxidise within weeks. The oxidation returns faster after the first time because the outer factory coating has already been removed. A proper UV sealant extends the restored condition for one to two years under typical UK conditions.

The improvement from a professional headlight restoration is often dramatic. Lenses that were transmitting perhaps half of the intended light output can be restored to close to their original transmission. That improvement is visible both to the driver in terms of night visibility and to other road users in terms of the vehicle's light pattern.

From an MOT perspective, a headlight that has deteriorated enough to fail the light intensity test becomes an MOT failure. Restoration at £40 per unit or £80 per pair is considerably less expensive than sourcing replacement headlight units for most vehicles, particularly those with adaptive or LED headlight systems where units can cost several hundred pounds each.
