While statistics compiled by the Insurance Institute for Highway Safety (IIHS) show that about half of all fatal crashes in the U.S. occur in the dark, and more than a quarter occurs on unlit roads, only 32 out of 165 new-vehicle models evaluated by the institute in 2018 achieved a ‘good’ rating, with 75 models assessed as marginal or poor.
To make matters worse, recent research by the AAA found that ‘clouded or yellowed’ polycarbonate headlights in aging vehicles only provide 22 percent of the illumination of new headlights – this decrease due to mechanical and chemical degradation caused by air pollution, road grime, and the various wavelengths of ultraviolet light. This degradation not only makes night-time driving dangerous, but in more extreme cases can render the vehicle unroadworthy.

However, according to the AAA, revamping headlights using one of the best headlight restoration kits can return the illumination to approximately 70 percent of the original performance – at a fraction of the cost of replacing the units.
This explains the proliferation of professional and DIY headlight restoration kits. While the contents of the kits may vary, they will typically contain:
- Multiple grades of abrasives, with ascending levels of grit, to remove the discolored top-layer from the headlight
- Plastic Cleaner
- Microfiber Cloth
- Polish for buffing out fine scratches and smoothing the surface.
- Many kits also include a UV-resistant coating that can be wiped or sprayed on.
Some kits are intended for use with power tools, in which case the abrasives, polish and cloth may come in the form of discs and pads designed for use with a drill.

Shopping For The Best Headlight Restoration KitsEven though many of the products found in these kits – such as the abrasives, sealers and Ultra Violet blockers can be purchased separately over the counter, it is far easier to purchase a complete kit.However, to gain the full benefit of a headlight restoration kit it is important that the consumer select a product that best suits the specific application.Despite the seemingly endless range of features advertised by the many manufacturers promoting their products in the marketplace, the consumer needs to look for the following information when evaluating the best headlight restoration kits:
- Does the kit suit the headlight condition? Severely discolored headlights with significant surface damage will need more restoration. In cases like this, it is advisable to opt for a heavy-duty kit, such as 3M’s highly acclaimed general Headlight Lens Restoration System, that includes additional restorative materials and allows for drill-activated sanding to provide maximum clarity.On the other hand, if the headlight is only slightly discolored because of road grime or pollution, rather than UV degradation and mechanical damage, a cheaper single application product may suffice.
- Single- versus multi-stage kits. Even though a one-step process may sound promising, these kits typically only contain a cleaning solution. So, while these may work on lightly contaminated lenses, they really don’t address the root cause of the discoloration, namely the deterioration of the plastic surface. Multi-stage kits also include abrasives, and even Ultra Violet protectors and polishes. This comprehensive approach makes a huge difference to the quality and longevity of the headlamp restoration.
- Comprehensive kit content. Very often this is what sets the best headlight restoration kits apart from the rest: Higher-quality kits tend to include everything required for the restoration, including cleaning and sealing solutions, gloves, towel, and several grades of sandpaper. And although one may expect to pay more for such a comprehensive kit, there are many manufacturers that supply products that are very reasonably priced – take for instance Rust-Oleum’s HDLCAL best priced Wipe New Headlight Restore, that comes complete with a ‘Wipe-It’ packet, headlight polishing pad, microfiber cloth, and a pair of gloves.
- Manual- versus tool-restoration process. The choice of restoration method really makes no difference to the quality of the end result. The use of a drill or sander can, however, make the work easier if the lens is severely damaged requiring more intensive rectification.
- How easy is the kit to use? Even though most headlight restoration kits are fairly easy to use, it is nevertheless worth reading the instructions to make sure the application requires no special skills or equipment.There are also kits – for example this review’s premium choice, Meguiar’s G2000 Perfect Clarity Two Step Headlight Restoration Kit – that are specifically aimed at simplifying the process by reducing the number of steps.
- Does the kit come with a UV-blocker? This is definitely something that a good headlight restoration kit should include. Treating the lens with a UV-blocker cuts down on maintenance and slows down the yellowing, oxidization, and clouding process – especially in harsh climatic conditions.
- Be wary of lens-specific products. Be on the lookout for kits formulated for specific lens material-types. Although headlights are usually made from some type of polycarbonate plastic, the exact chemical compositions can vary. Thus, unless the composition is known it is better to stay away from specialist products.
- Pricing. The relatively low cost of these restoration kits means that pricing really does not play a significant part, however, it is always worth equating features to the product’s price when comparing different brands. Even though kits may vary in price, ease of use, and effectiveness – with some requiring power tools – the best headlight restoration will usually require several steps to complete the work.
The Best Headlight Restoration Results
It is best to tackle headlight restoration when weather conditions are dry, this makes the application of any compounds a little easier.
Headlamps that are badly discolored and scratched or pitted will require more sanding to remove the damaged top layer, but in general, the basic methodology remains the same:
- Clean the lens with either water or ordinary household cleaner to remove surface dirt.
- Using abrasive paper remove the damaged surface layer. This is usually done using progressively finer abrasives that finally buff the lens to a smooth finish – typically 500-, 800-, 1000-, and finally 3000-grit.
- Once the hard surface layer has been removed and smoothed down, a polishing compound is normally applied, preferably with a microfiber cloth.
Although many kits end with this step several of the best headlight restoration kits have one or even two further steps:
- Some kits include a sealer, which can be applied with a microfiber cloth.
- In many restoration kits the final step consists of applying a UV sealant. Whether it comes with the kit or not, UV protection is the best defense against untimely oxidation.
NOTE: While these are typically the steps to follow, when restoring discolored and damaged headlights, it is always advisable to follow the manufacturer’s instructions.
Even if the process is quite straightforward there are bound to be unanswered questions, which the following section seeks to address.

With more and more vehicles being equipped with headlights with polycarbonate lenses it is likely that headlamp refurbishment may become commonplace, it is therefore important that the consumer is well informed about how to select the best headlamp restoration kit. Choosing and successfully applying the correct restoration kit is not only critical to safe evening travel, but by improving the appearance of the vehicle, also enhances the resale value.
Removing the damaged and discolored surface layer can bring about a significant improvement in night time visibility. The improvement will largely depend on the level of damage the lens incurred before the restoration, but could be as high as 95 percent.
While there is no definitive answer to this question, under normal conditions once a year should suffice. However, in extreme climates where the vehicle is subjected to harsh sunshine for extended periods, or if the vehicle is regularly driven on gravel or heavily salted roads, restoration could be carried out when the lenses become discolored or show visible signs of pitting.
It is important to note that, because the headlight restoration process includes resurfacing the lenses by removing material, unnecessary treatment should be avoided.
Typically, headlight restoration treatments can last for between 10 months and 3 years depending on several factors such as the type of lens, the restoration process, environmental circumstances, and the operating conditions the vehicle is subjected to.
Treating the lenses with UV-blocker and regularly washing the headlights will extend the life of the treatment.
There are several factors that can lead to headlights becoming cloudy or yellow. Many of these stem from the environment – including exposure to high levels of UV light – in which the vehicle operates.
