How to replace lights to pass inspection?

Many car owners struggle with choosing the right headlights to replace old, damaged ones so that the vehicle inspection goes smoothly and is not rejected.

After a period of time when inspection units tightened regulations on checking lighting items, according to inspection centers, the situation of car owners arbitrarily "upgrading" front lights and fog lights that do not meet regulations has decreased significantly.

However, many car owners are still wondering how to replace new headlights when the old ones are damaged or broken to ensure compliance with regulations and convenience in the next vehicle inspection.

How to replace headlights to pass vehicle inspection is still a "hot" topic of interest to many car owners today (illustrative photo).

A representative of a vehicle inspection center said that when replacing the front light cluster, car owners should go to reputable, genuine establishments to buy the same type of light as the old light cluster (original light from the manufacturer).

At the same time, make sure the light cluster is installed firmly, in the correct position, and the color of the lights on both sides must be the same white or yellow.

In addition, the car owner needs to request the auto garage to provide a photocopy of the certificate of conformity declaration according to the National Technical Regulation on optical characteristics of front lights of road motor vehicles (QCVN 35:2017/BGTVT).

This helps the vehicle owner verify that the replacement lamp is in compliance with Vietnamese technical standards, has been assessed and certified by the state management agency for conformity and is allowed to circulate on the market; and ensures that there are documents to present when registering the vehicle during the periodic inspection, ensuring that all necessary documents are met when registering the vehicle.

In case of only replacing the bulb in the lighting cluster, it is now allowed to replace the bulb of a different type such as from halogen to LED, but the power consumption of the LED must be lower or equivalent to the halogen bulb. When replacing, there is no need to intervene or change the structure of the cluster, then it can be inspected normally.

Car owners should note not to replace halogen lights with projectors (Halogen, Xenon, LED) because to install, the headlight will have to be drilled and this inspection item will fail.

However, if the original car is equipped with halogen projectors, it can be replaced with other types of projectors (LED projectors). Note that the projectors must be of the type that do not require drilling or modification and can still be installed normally to pass inspection.

Regarding fog lights, according to current regulations, vehicle owners are allowed to install additional separate fog lights but must comply with the regulations in Vietnam Standard TCVN 6978:2001 on road vehicles - installation of lighting and signal lights on motor vehicles and trailers.

Specifically, the following criteria must be followed: 2 symmetrical white or yellow lights must be installed; the installation location must not be more than 400mm from the outer edge of the vehicle and the height must not be less than 250mm; the lights must be directed towards the front of the vehicle; the fog lights must be turned on and off independently of the front lights.

Regarding the light direction, it is necessary to ensure that the light beam from the additional fog lamp does not shine upwards and must be below the horizontal line of the new lamp measuring device to be approved by the inspection unit, confirming that it has passed the inspection category of this type of lamp.

Because if the light beam of the fog lights shines upwards, it can dazzle drivers of other vehicles traveling in the opposite direction, potentially posing a traffic safety risk.
