Replacing a license plate is a procedure that almost every car owner faces. The cause may be physical damage to the plastic from reagents, paint burnout, or a simple breakdown of fasteners. Drivers often ignore defects on this element, however loss of readability or deformation may lead to fines from traffic police inspectors.

The replacement process seems trivial, but it requires compliance with certain rules so as not to damage the state registration plate (GRP) itself or the car body. In this article we will look at how to properly dismantle the old frame, choose a high-quality replacement and install it without violating the law. We will pay special attention GOST R 50577-2018, which regulates the requirements for license plate mounts.

Many motorists are wondering whether it is even possible to change this element themselves, or whether this requires a visit to a service center. The answer is clear: independent replacement is allowed and does not require documentation if the new element meets the standards. The main thing is to avoid hiding important elements of the mark, such as the region code or flag of the Russian Federation.

Never, they are factory

Before you begin, you need to prepare the tools and choose the appropriate frame model. There are many options on the market: from standard plastic ones to reinforced metal ones with backlighting. It is important to understand that cheap plastic can become brittle in the cold, which will lead to its destruction at the most inopportune moment. Therefore the choice quality material is the first step towards durability.

Choosing the right number frame

The car accessories market is overflowing with offers, but not all of them are legal and safe. The standard frame must have four holes with a diameter of 9 mm for attaching the sign and two holes for mounting on the body. The distance between the centers of the mounting holes is strictly regulated and is 335 mm. Deviation from this parameter will make installation impossible without drilling new holes in the body.

When choosing, you should pay attention to the presence of additional elements that may be regarded by the inspector as a violation. For example, frames with writing that overlap part of the character field, or that obscure the area code area, are not acceptable. Readability must be absolute in any lighting.

  • 🚗 Material: It is preferable to choose frost-resistant plastic (ABS) or stainless steel so that the frame is not damaged by reagents.
  • 📏 Geometry: Make sure the frame has clear field separators that match the format of the Russian license plate.
  • 💡 Backlight: If you choose a frame with LED backlighting, check that it does not create glare that interferes with the cameras reading the license plate.

A special category consists of the so-called “European” frames, which are often wider than the standard Russian ones. Installing such a frame on a Russian license plate will result in the edges of the sign being cut off or hidden, which is a direct violation. Always check product labeling for compliance GOST.

⚠️ Attention! The use of frames that hide at least one symbol or element of the sign (including the frame of the sign itself) entails a fine under Part 1 of Art. 12.2 Code of Administrative Offenses of the Russian Federation. Make sure your new frame has cutouts or clear inserts for all letters and numbers.

💡

Buy frames with rubber or plastic plugs for screws included - this will protect the fasteners from corrosion and give a neat look.

Necessary tools and preparation

For a successful replacement you do not need a complex professional tool. A basic set can be found in most drivers' garages. However, using unsuitable tools may result in broken bolt edges or scratches in the paintwork of the bumper.

The main difficulty is that old bolts often stick due to moisture and dirt. Therefore, before starting work, it is recommended to treat the fasteners with a penetrating lubricant, such as WD-40 or its analogues. This will greatly facilitate the dismantling process.

  • 🔧 Keys: a set of open-end or socket wrenches (usually 10 mm) or a ratchet with a head.
  • 🧴 Chemistry: penetrating lubricant and contact cleaner for processing electrical equipment (if the frame is illuminated).
  • 🧤 Protection: gloves to protect hands from dirt and sharp metal edges.

If you are replacing the backlit frame, you will also need a multimeter to test the circuit and electrical tape or heat shrink to insulate the connections. It is better to carry out electrical work with the battery terminal disconnected to avoid a short circuit.

Removing the old license plate

The process of removing the old frame begins with a visual inspection of the fasteners. Often the screws are covered with decorative plugs that need to be carefully removed. You should act carefully so as not to damage the license plate itself, since restoring it is more expensive than replacing the frame.

If the screws are rusty and won't come off, don't try too hard right away. Apply lubricant generously and wait 10-15 minutes. Sharp jerks can lead to breakage of the bolt head, after which it will be extremely difficult to remove the remainder without drilling.

When removing the backlit frame, first disconnect the electrical connector. It is usually located under the hood or behind the trunk trim. After turning off the power, you can begin to unscrew the fasteners.

⚠️ Attention! If the license plate is deformed or cracked, it may permanently collapse when the frame is removed. In this case, prepare in advance to obtain a duplicate number from the traffic police or from specialized manufacturers.

What to do if the bolt is broken?

If the head of the bolt is licked off, try using an extractor or carefully drilling out the center of the bolt with a smaller drill bit, then knock out the remains. In extreme cases, you will have to remove the bumper to access the back side.

Installing a new frame: step-by-step instructions

Installation of a new frame begins with “trying on”. Loosely insert the license plate into the frame and make sure that all characters are visible and the holes line up. If the frame has an adjustable width (telescopic), adjust it to the size of the sign.

Frame the number. For this, special screws or latches are used. It is important not to overtighten them so that the plastic does not burst, but also not to leave them loose so that the sign does not dangle. After this, align the frame holes with the holes on the car body.

Insert the mounting bolts. If you are using old bolts, remove any rust from them with a brush. New bolts should be coated with lithium grease or copper spray to prevent future corrosion. Tighten the bolts evenly, alternately tightening the upper and lower ones.

Stage Action Important nuance
1. Preparation Cleaning the installation site Remove dirt and old grease
2. Fixation of the sign Fastening the GRZ to the frame Do not overtighten the screws
3. Installation Body installation Use new bolts
4. Check Reliability control Checking for play

The final touch is to install decorative caps on the bolt heads. This not only improves the appearance, but also protects the threads from water ingress. Make sure the license plate does not vibrate when you tap it with your hand.

💡

Using new fasteners is a guarantee that you will not have to repeat the procedure in six months due to rust.

Connecting the license plate light

If you choose a frame with integrated LED lighting, the process is complicated by the need for an electrical connection. Stock backlight bulbs often produce dim light, so LED bezels are a popular upgrade. However, the connection must be made correctly.

First determine the polarity of the wires. In cars with an on-board 12 Volt network, it is important not to confuse the plus and minus, although for LEDs this may not be so critical if there is a diode bridge in the circuit, but it is better to follow the diagram. Usually the plus is taken from the standard backlight wire, and the minus is thrown onto the body (ground).

Connection diagram:

Plus (+) frame -> Wire of the standard backlight lamp


Minus (-) frames -> Car body (bolt on metal)

All connections must be securely insulated. Use heat shrink tubing and heat it with a hairdryer to create a tight seal. Regular electrical tape can come off due to moisture over time, which will lead to oxidation of the contacts and failure of the backlight.

  • 💡 Brightness: Make sure the LEDs light up smoothly and without flickering.
  • 🔌 Connector: use standard connectors (for example, W5W or special connectors) so as not to cut the car wiring.
  • 🛡️ Protection: the place where the wire enters the frame must be hermetically sealed.

After connecting, turn on the side lights and check the operation of the backlight. It should light up simultaneously with other external lighting devices. If the backlight only works when the brake light is on, then you have connected to the wrong circuit.

The issue of the legality of number frames is regulated quite strictly. The main requirement is that the frame should not cover any character, number or letter, as well as the flag and region code. Even a slight darkening of the corners can cause the inspector to stop.

There is a myth that frames with inscriptions of cities or car brands are completely prohibited. This is wrong. They are allowed if they are located in special fields provided for by the design of the frame and do not overlap the elements of the state registration plate. GOST allows the presence of inscriptions outside the field of the sign.

The fine for incorrect installation or the use of non-standard frames that hide numbers is 500 rubles (Part 1 of Article 12.2 of the Code of Administrative Offenses of the Russian Federation). However, if it is proven that the frame was used for hiding the number in order to avoid recording violations, the fine may increase to 5,000 rubles or lead to deprivation of rights.

⚠️ Attention! Flip frames or frames with mechanical shutters that hide the number are classified as number concealment devices. Their use may result in deprivation of rights for a period of 6 months to 1 year.

Can the frame be painted to match the body color?

Yes, you can, if the symbols, numbers or flag field were not filled in during painting. The main requirement is the readability of all elements of the sign.

Common problems and their solutions

Car owners often encounter license plate rattling at high speed. This occurs due to the loose fit of the frame to the bumper. You can solve the problem by placing a thin layer of vibration insulation under the frame or rubber washers on the mounting bolts.

Another problem is clouding of the plastic. Cheap frames quickly lose transparency and turn yellow when exposed to ultraviolet radiation. If this happens, polish the plastic with a special polish, but it is more effective to simply replace the frame with a better one with UV protection.

Bolt corrosion is a perennial problem. To avoid this, use stainless steel or brass bolts. Before installation, lubricate the threads with graphite lubricant. This will extend the life of the mounts by several years even in harsh winter conditions.

  • 🔊 Noise: Use anti-vibration stickers between the number and the frame.
  • 🌫️ Cloudiness: choose frames made of polycarbonate, they are more resistant to fading.
  • 🧊 Ice: In winter, carefully clear the frame of ice, without using sharp objects, so as not to chip the plastic.
Is it possible to use a frame without holes, with magnets?

The use of magnetic frames is not formally prohibited if the license plate itself is installed properly and reliably. However, if the inspector decides that this design makes it easy to hide the number, questions may arise. In addition, the magnets may fail at high speeds.

Do I need to register the frame replacement with the traffic police?

No, the license plate is considered an additional accessory and does not require changes to the vehicle registration documents (STS, PTS).

What should I do if the holes on the new frame do not match the old ones?

Drilling new holes in the bumper is not recommended. It's best to look for a frame with a universal slide or use an adapter plate if possible. As a last resort, you can carefully widen the existing holes in the frame itself, if the material allows.

Are frames with tuning studio logos allowed?

Yes, they are allowed if the logo is located outside the state registration plate area and does not distract attention from the number itself.

How to clean the frame from bitumen and reagents?

Use special bitumen stain cleaners or regular kerosene/white spirit. Apply the product to a rag and gently wipe the contaminated areas, avoiding contact with aggressive chemicals on the body paint.
