Cloudy headlights will not only damage the appearance of the car. They can also reduce visibility at night, which is a safety hazard. Mothers NuLens Headlight Renewal Kit claims that it can repair yellow or foggy headlights, so our product review team tested it.

This review will cover the effectiveness of Mothers NuLens headlight cleaner, discuss its ease of use, and give a sensible view of the overall value of the product. Based on extensive testing, we ranked Mothers NuLens headlight repair kit as one of the five best headlight repair kits on the market in 2021.

-A large number of materials can be reused

-Can be used for headlights or taillights

-Restore the headlights that have been severely sunburned

-If you do not have much experience, you may encounter difficulties in the operation exercise

-The result is no different from a hand wash washing machine

For headlight repair products, Mothers NuLens requires wet grinding. The process involves using water to help lubricate the grinding wheel to help better clean the headlight lenses.  

In addition to the instructions, the Mothers NuLens headlight update kit only comes with the following four items:

Mothers NuLens assumes that you have a drill on hand during the repair process. If not, you need to buy one. The other items you need are car wash materials and microfiber towels for wiping the headlights between steps. The use of masking tape is also encouraged to help protect the area around the headlights.

When testing the Mothers NuLens headlight update kit, we mainly looked at three factors: the result, the clarity of the description, and the price.

In our tests, we tried to repair the headlights that were badly sunburned. Although the instructions say that multiple passes may be required to achieve the required clarity, we limited the test to a complete run.

Before putting the sandpaper on the plastic, we cleaned the headlights to make sure we did not sand any dirt or grime to the existing plastic. After cleaning, we sand the headlight with wet sandpaper with various sandpaper until it meets the manufacturer's specifications. Then we polished the headlight and cleaned it with a microfiber towel until it reached a polished appearance.

In addition to the entire process which only takes about 20 minutes to complete, our review team also likes the Mothers NuLens headlight update kit very much. It is equipped with enough extra materials to repair two or three other cars, and there is also sandpaper and polish left.

The repair disk works well, and it only takes a few times to remove the oxidation buildup on the headlights. We also did not leave any ugly hairline scratches, the polish cleaned the headlights immediately.

Although Mothers NuLens provides customers with a large amount of materials for subsequent work, the update kit only comes with a 3,000 grit grinding wheel. Although this disc is the heaviest and should be used more as a refining tool, it is ideal to have more than one.

One problem with the use of drill bits is that areas such as the corners and curves of the headlight become hard to reach and difficult to sharpen properly. If you find uneven areas or stains after a few passes, you can use a grinding wheel to remedy them. We should also mention that if you are not accustomed to using drill bits, it may be difficult to guide the sand pad.

After receiving more than 7,600 customer ratings, the Mothers NuLens Headlight Renewal Kit has an average rating of 4.3 on Amazon (out of 5.0 stars). 79% of users think the product is worthy of four or five stars, and 61% of users give it five stars.

Many customer reviews emphasized that the Mothers NuLens headlight update kit is quick and easy to use. They also tend to mention its affordability.

"Excellent! My headlights look as clear and shiny as new! There are still a lot of polishes that will be used on my motorcycle."

"Each lamp took me about 20 minutes. When you started to polish the lens with 800 grit sandpaper... After polishing the sponge, everything came together. I was impressed. It only cost 15 dollars and some elbows. It’s a good value for money (using a cordless drill)."

Some of the more important comments said that the oxidation remover was not working properly, or that the kit did a poor job of improving clarity. However, in other comments, users admitted that they did not follow the instructions correctly.

"I followed the instructions, but all it did was make things worse. It polished a lot of yellowing [material] into a pile of headlights that I couldn't polish. I tried all four sanding pads that came with the kit , They are all worn out and fall apart... This is a headlight."

"I have tried the polishing compound twice in this kit now, but it does not work as advertised... So far, I have tried [the kit] once, but without success. The polishing pad does not seem to work Too easy to use, polishes and pads/balls are not very effective at polishing the sanding marks."

Like any repair tool, Mothers NuLens Headlight Renewal Kit is not perfect. However, it can be very effective. The following is our team's overall rating and category rating (out of 5.0 stars).

If your headlights are cloudy and you want a simple DIY project that can be completed quickly, you might consider buying this product. However, if your car's headlights are already clear, or you are not accustomed to using drill bits, then the Mothers NuLens headlight update kit is not for you.

If you prefer to deal with this project without power tools, Sylvania headlight repair kit or Chemical Guys headlight repairer may be a better choice.

How do you use the Mothers NuLens headlight update kit?

There are several steps required to use the Mothers NuLens headlight update kit. The first is to place a suitable sanding disc on the drill attachment. Next is to polish the headlights to maintain consistency. After sanding, you will apply Mothers NuLens polish until the desired transparency is achieved.

Is the headlight repair kit useful?

Using a headlight repair kit is an inexpensive way to save headlights damaged by the sun. Although they are very good at removing yellowing, don't expect to have new-looking headlight lenses unless you want to spend a few hours polishing them.

How long can the headlight repair kit be used?

The life of the headlight repair kit results depends on the materials used. These kits are specifically designed to remove turbidity caused by ultraviolet rays, so if the kit is not equipped with a protective sealant to prevent sun exposure, you may find yourself revisiting the repair process faster than you want.
