Description
Yellow headlights are not dirt, and no amount of washing will bring them back.
Headlight lenses are polycarbonate, and polycarbonate goes cloudy because the factory UV coating breaks down under sunlight. Once that layer fails, the plastic underneath oxidises, light scatters instead of projecting, and the beam that passed inspection three years ago starts throwing a dull smear down the road. Replacement units cost real money and usually need the bumper moved to fit them. Refinishing the lens removes the failed layer and puts a new surface back on it.
This kit is built around a three-inch backing pad and an M16 adapter, which lets the work happen on a cordless drill rather than by hand. That matters: a drill keeps the pad flat and the pressure even, which is how you avoid the hollow spots and swirl marks that hand sanding leaves behind. The discs step through the grits in sequence to strip the coating and level the plastic, and the polishing pad takes it back to a clear finish. Twenty-one pieces means a full sequence plus spares rather than one pass worth of consumables.
The sequence is the part most people get wrong. Coarse first to cut the dead layer, then progressively finer to remove the scratches each previous disc left, then polish and seal. Skipping a grade is what produces a lens that looks better for a week and then dulls again, because the fine scratches scatter light as badly as the original oxidation. Follow the order, keep the pad moving, and both lenses on a car can be done in an afternoon.
Two hours of drill work versus two replacement units and a bumper job. The arithmetic is not close.

Where It Belongs
This is the tool for the car that is mechanically sound and cosmetically tired, which is most cars past their sixth year. It suits a weekend owner restoring a vehicle before a sale, a workshop that wants to offer lens refinishing without buying a dedicated polisher, a fleet operation bringing a row of vans back to a presentable standard, and anyone facing an inspection where beam pattern matters. It also works on motorcycle screens and plastic tail light clusters, and the same drill-mounted process handles paint correction on small panels once the right pads are fitted.
Questions, Answered
Q. Will this fix badly yellowed lenses?
Yes, up to the point where the plastic itself is crazed or cracked. Surface oxidation and coating failure are exactly what the grit sequence removes.
Q. Do I need a special machine?
No. A normal cordless drill with the M16 adapter is the intended setup, and the drill holds the pad flatter than hand sanding can.
Q. How long does one car take?
Two lenses in an afternoon for a first attempt, including masking and clean-up. Subsequent cars go faster because the technique is the slow part.
Q. Do I need to seal the lens afterwards?
The polished surface benefits from a UV sealant or a clear coat. Without one, the plastic will begin to oxidise again over months.
Q. Can I use it wet or dry?
Keep the pad moving and follow the grit order. Wet sanding reduces dust and heat, dry cutting removes material faster.
Q. Are the discs a standard size?
Yes, three-inch discs and pads are widely available, so the kit keeps working after the supplied consumables are used.
