The Rain‑X Headlight Restoration Kit provides a deep clean to yellowed, hazed headlights with the use of a specially designed polish and sealant. Over time, headlight lenses become oxidized rendering them hazy and yellow. This causes headlights to shine less brightly, which is dangerous for the driver and others on the road. For the last 40 years, Rain‑X has provided drivers with products to help them outsmart the elements. All Rain‑X products are designed to help keep our customers a confident step ahead of Mother Nature on the road.
