​​Is it necessary to register an LED screen on the roof? The pitfalls that veteran drivers have stepped on​ ​
Recently, a friend asked me: "Old Wang, I want to install an LED top screen in this taxi. How do I complete the registration procedures? "This question is a question! The roof screens of taxis on the streets are now dazzling, but do you know? Last year, more than 200 cars in our city were fined for incomplete procedures. Let’s talk about this today, and you will understand it after listening!

​​1. Registration is not something you can hide just if you want to​​
Let me tell you a real story first: Last year, a buddy posted a 3㎡ LED screen on the roof of the car, and thought "it was just a small piece without filing." As a result, he was caught by the traffic police and fined 500 yuan and had to be dismantled and reinstalled. ​ ​Here is a key number to remember: if the color change or the installation area exceeds 30% of the body, it must be registered! ​ ​ Think about it, the roof of an ordinary car is about 1.5-2㎡. If you install a screen of more than 1㎡, it will definitely exceed 30%.

​​Have you prepared all the three-piece registration sets? ​ ​

• ID card + copy of the driving license (remember to both front and back)
• Original vehicle registration certificate (don't lose the green notebook)
• Modification plan drawings (requires the screen size and installation position)

I'm going to knock on the blackboard here! ​ ​Special vehicles should not be used randomly​ ​For example, the blue and white stripes of police cars and the red cross of ambulances, the car was directly detained if it was used by ordinary cars. When we install advertising screens, it is best to choose regular colors such as red, yellow and blue to avoid trouble.

​​2. Five steps to complete the registration procedures​​

1. ​​Call in advance to make an appointment​ ​: Don't just rush to the vehicle management office, now you have to call 122 to make an appointment first
2. ​​All violations have been handled​ ​: If there is a system that has not paid a fine, you can apply directly
3. ​​Fill in the application form on site​ ​: Get the form at the service window, remember to bring a black water pen
4. ​​Don't be afraid of car inspection​ ​: Staff will check the safety of LED screen circuits, focusing on whether there is any leakage risk
5. ​​Receive a new certificate​ ​: After obtaining the new driving license, check the license plate number and frame number on the spot.

Here is a tip for saving money:​ ​Change the color and add equipment can be done together​ ​, save two trips. Last time I helped my friend get it, it only took 2 hours from entering the door to getting the certificate, which was very efficient!

​​3. Fatal details before and after installation​​
​​Three iron rules for selecting screens​​：

• ​​Waterproof level at least IP65​ ​(You don’t have to worry about short circuits on heavy rains)
• ​​Double insurance must be connected to power supply​ ​(Don't just take the on-board circuit)
• ​​Aviation aluminum material should be used in the frame​ ​(The screen will not fly out when the brakes are sudden)

Let me talk about the negative textbook: A certain team has a cheap picture and installed a screen without a voltage regulator. As a result, the screen will be black as soon as the air conditioner is turned on, and it costs three times more to rework. ​ ​The key point here: The power cord must be equipped with a 10A fuse, and the wire diameter must not be less than 1.5mm²​​。

Remember when installing​ ​Take photos and keep them in the bottom​ ​! From unpacking to wiring completion, every step is taken clearly. In case of problems in the future, these photos will be your "Golden Medal for Immunity".

​​4. Blood and tears advice from veteran drivers​​

1. ​​Brightness should not exceed 4000cd/m²​ ​: If you are too bright and dazzling, you will be reported. Don't ask me how I know
2. ​​Content review must be advanced​ ​: The advertising slogan contains absolute terms such as "most" and "first", and the Industrial and Commercial Bureau will ask you for tea every minute
3. ​​Annual inspection is required every year​ ​: Cars with LED screens are modified vehicles, and they must go to designated inspection stations during annual inspection.

There is a cold knowledge you may not know:​ ​The registered LED screen is considered legal components of the vehicle​ ​, you will be compensated if you have an accident insurance! Last year, a car rear-ended, and the insurance company refused to compensate for the screen loss, but later it took out the filing certificate and lost more than 8,000 yuan.

Finally, I would like to say that it is really important to make more advertising fees when installing a top screen now, but​ ​Legality and compliance are the long-term solution​ ​. Don’t worry about the registration fee of hundreds of yuan. Think about the losses caused by deducting and shutting down the vehicle. You know which end is light and which end is heavy. Next time I see the blinding screen on the road, remember to remind me: "Brother, it's time to register! "
