Presumably many experienced drivers will have had such an extremely painful experience. You are driving happily, and suddenly a car with extremely dazzling lights appears on the opposite side, blinding your eyes. At this time, you quickly turn on the high beam to "flash" to remind the other person to turn off the high beam.
I never thought that my headlights would be "dim"
After flashing the other party several times in succession
There was no response from the car coming from the opposite direction, and I instantly felt desperate.
Later, after the car enthusiasts group talked about this matter, it resonated with many car enthusiasts. They all said: When I first bought the car, I could feel that the light was sufficient as soon as the headlights were turned on, but over time, the The light coming out is not that bright! Especially at night, the feeling was more obvious. Later, after careful observation, I found that the lampshade was "yellowing and blurry"!
Lampshade "makes trouble"
I believe many people are facing the same problem:
“Why do car headlights turn yellow and blurry?”
Actually the answer is very simple
Because most of the headlight glass covers on the market
They are all made of high-grade polycarbonate.
It’s the common “resin” spectacle lens
Anyone who has studied physics knows that
Polycarbonate is a material that oxidizes over time
Once dirt is generated,
It is difficult to clean with ordinary detergents
The harm caused by "damaged" car lights
Car light covers are crucial to car driving
Its brightness and the degree of transparency of the lampshade also determine
our our safety of driving at night
You know, 22% of traffic accidents every year
Occurs in poor visibility conditions
Due to the dim color of the lighting
Caused by the driver's inability to brake and avoid in time
When the lampshade is dim and the light transmittance of the car lights is low,
Not only affects driving safety
Even the "annual inspection" of cars is a big problem
Let’s talk about the trickier part of the test.
It’s the light brightness detection
When the brightness standard is not met, a re-inspection fee will be charged
Sometimes it’s only discovered after rechecking several times
It turns out that the problem is not the brightness of the bulb, but the blurred lampshade.
In the end, going back and forth is not only a waste of money but also time-consuming.
You don’t need to replace the headlights to make your car lights brighter
Encountered a situation where the lampshade becomes blurred or yellowed
The first reaction of many car owners is to replace the headlights with new ones.
I checked online and found that new car lights cost 1,500 yuan/pair.
The cheapest sub-factory costs nearly 600 yuan
Faced with such high costs
Look at my wallet again, it makes me feel sick just thinking about it
Having said that, it would be better if you just bite the bullet and replace it with original parts.
If you are greedy for cheap and buy low-quality sub-factory parts
After long-term exposure to the sun, the same situation occurs again
In the final analysis, the root cause of the problem is still not solved.
Later, after learning from many sources, I found out
When the lampshade becomes blurry, scratched or yellowed
No need to spend a lot of money to replace new car lights
It can also fully repair the damaged lampshade surface
The most important thing is that the money spent is actually
It’s only 1/10 the price of replacing a new car light
For "headlight repair" problem
A few popular tips on the Internet:
There is “Toothpaste” for daily use
"Polishing wax" for car paint
The best-selling online "spray headlight repair agent"
The best-selling "Alexin headlight refurbishment agent" in the mall
Borrowed an old model commercial vehicle
As you can see from the picture
The headlight cover of this Dongfeng Fengxing Lingzhi is old.
There is a deep layer of "film" on the surface
Due to the problem with the lampshade, visibility is extremely poor when driving at night.
Today we will focus on these tips for repairing lampshades online.
Let me give you a review
Let’s see which method is the most direct and effective
Tips for repairing lampshades
Toothpaste Scrub/Repair
Toothpaste itself has the effect of "cleaning dirt"
We will apply a little toothpaste on the car cleaning cloth or soft cloth
Wipe the headlight cover in a circular motion
Rub each lamp for 3 to 5 minutes
After it's almost wiped, wash it with clean water several times.
After we clean it with toothpaste
It was found that the surface of the lampshade was cleaned very clean
But oxidation and blurring have not been well improved.
Tips for repairing lampshades
Polishing/repairing
It is obvious that when the surface of the lampshade is severely oxidized
Use toothpaste to remove it, this method fails
But if it’s just a daily stain on the lampshade
From a cleaning perspective, the results are ideal
Next, we use "polishing compound" to test
Let's see what kind of performance it will have
The operation method is the same as toothpaste cleaning
Rub the lampshade with a sponge and rub it in a circular motion.
Observe from the effect after wiping
The surface brightness of the headlights has indeed improved
The overall effect is much better than toothpaste
When the surface of the lampshade appears yellow or stained
Car enthusiasts can use polishing wax for polishing
But if the lampshade is oxidized
The effect of polishing wax is not obvious
Tips for repairing lampshades
Spray car light repair agent/repair
The actual testing is still ongoing, in order to make the lampshade perfectly repaired
Lun Gu searched and bought 1 bottle on a certain treasure.
It is said that as long as the car lights are scratched, yellowed or cracked,
Repair with just one spray
Open the dense operating instructions
After spending 10 minutes reading it, I rolled up my sleeves and started
▲Clean the surface with a rag first
After going through the above 4 steps
Final paint repair
Spray 3 times in total, with an interval of 5 to 10 minutes between each application
A distance of about 5cm from the lampshade
After 1 hour of operation
Let’s take a look at the results of the final test
There were some hiccups during the operation
Failure to control the spraying distance resulted in tears on the surface
The grinding work has to be repeated again
Finally, from the before and after comparison pictures
Compared with the previous toothpaste and polishing wax,
The effect is still very obvious, the lampshade is transparent and bright
And the original yellowed spots are no longer visible.
The disadvantage is that the operation is complicated and the construction is troublesome.
Tips for repairing lampshades
Liquid application headlight refurbishment/repair
Next, let’s test a “liquid” repair agent
The ingredients contained in such a small bottle
Silicone oil, abrasives and petroleum solvents
Specially used for resin car lights
Suitable for yellowing and aging car lights
Minor scratches on headlights caused by driving
Compared with the previous spraying of car light repair agent
The process has been simplified a lot
Similarly, clean the surface of the lampshade first
Then sand it with 800# and 2000# sandpaper respectively.
This wipe-on repair agent uses a "rubbing" method
Don’t worry about getting it on the car paint surface etc.
So we didn’t put any protective paper on it
We only need to apply it evenly on the surface of the lampshade
One car light, done in 15 minutes
After wiping, wait until the surface of the lampshade is dry.
It is recommended to wait for half an hour, and it is best not to touch the water during this period
Let’s take a look at the comparison effect
From the effect point of view, the effect can be said to be immediate.
The comparison before and after the restoration is completely different.
Repaired car lampshade
Already showing the same translucent effect as new car lights
And you can see that the cracks have almost been repaired
And the blurry situation has basically been alleviated
A closer look shows that the scratches and surface cracks have been basically repaired
I feel like I can fight for another five years!
A small bottle with a capacity of 15ml
I learned from the introduction that 3 pairs of car lights can be used
That is, the renovation of the "6" lampshades
After calculation, the cost is less than 10 yuan per time.
It seems to be a good deal in Lungu.
Instead of spending hundreds or thousands of dollars to replace the headlights
It's better to renovate the original car lights.
And the price difference is 100 times
No need to worry about wiring problems caused by replacing the lights
