Home / Knowledge base / Brake lights and rear lights, what's the difference?
LED brake lights and LED rear lights are important parts of your vehicle. Almost every vehicle is equipped with both brake lights and rear lights, which are located at the rear of your vehicle. But what exactly are these lights for and what is the difference between brake lights and rear lights? We'll explain that to you in this blog!

The difference between brake lights and rear lights, we explain it to you!
The LED brake light warns fellow road users when you reduce speed, for example at a traffic light, to avoid anticipation and accidents. If your car was put into service after 30 September 2001, it is mandatory to have a third brake lamp at the rear. A defective light can result in a €90 fine, regardless of whether the other two lights work. During the MOT inspection, all brake lights must function. The brake light is distinguished by its brightness; when you press the brake pedal, the brake lights will shine brighter than the other lights.
Rear lights
The purpose of the LED rear light is to make you visible to other road users. Especially in the dark or in bad weather, but also certainly during winter weather conditions, crucial. Visibility is essential, and not having these lights functioning or visible can lead to significant fines. During MOT inspection, all rear lights must work, similar to the requirements for brake lights.

Do the rules for brake lights and rear lights also apply to other vehicles?
As mentioned earlier, three brake lights and two rear lights are compulsory at the rear of a car put into service after 30 September 2001. But do these rules also apply to other vehicles, such as trucks, semi-trailers, motorbikes and agricultural vehicles? Rear lights and brake lights are mandatory on almost every motor vehicle, but the specific rules vary by type of vehicle. Below are the detailed rules for each type of vehicle.
Truck traffic
The same lighting requirements for brake lights and rear lights apply to HGVs as for passenger cars, but with some additional requirements. This still includes the requirement of two brake lights and two rear lights. In addition, additional line markings and two red reflectors must be present, a requirement that applies only to truck traffic and not to passenger cars.
Semi-Trailers
With semi-trailers, the lighting requirements are almost identical to those for passenger cars. The only difference is that only two brake lights are mandatory instead of three. There is no difference for rear lights compared to passenger cars, where two must also be present.
Motor vehicles
Slightly more complex rules apply to motor vehicles. For motorbikes, one rear light and one brake light are mandatory. However, if you have a three-wheeled motor vehicle with a width of 1.3 metres or wider, two brake lights and two rear lights must be present. Three-wheeled motor vehicles narrower than 1.3 metres may have one brake light and one rear light.
AGRICULTURAL VEHICLES
For agricultural vehicles the same rules apply as for truck traffic. This means that two brake lights and two rear lights are mandatory on this type of vehicle.
What do brake lights and rear lights have to comply with for the MOT?
Firstly, all lights must function correctly, be moisture-proof and produce an undistorted light image. Secondly, the lenses must be clear and unpainted. Finally, brake lights should be red or amber and rear lights should be red. The use of white is not allowed and will result in rejection and replacement.
Difference between halogen/LED brake lights and LED rear lights
The most commonly used light sources today are halogen and LED. This also applies to rear lights and brake lights. But what exactly is the difference between these light sources and which light source does TRALERT® recommend?
Halogen lighting
Halogen lamps have some advantages, including good light output and width, relatively low purchase cost and excellent colour rendering. However, they also have disadvantages, such as shorter lifespan compared to LED lighting, generating a lot of heat and inefficient use of energy, sensitivity to high voltages. Also, they may actually not be produced since 2018 due to environmental concerns. If you are looking for new lighting, you are less likely to come across halogen lamps because of these limitations.
LED lighting
LED lights offer numerous advantages. They are extremely energy-efficient, wasting almost no energy. The service life of LED lighting is up to 35 times longer than that of halogen lamps. LED lighting comes in different shapes and light colours, withstands peak voltages and offers a wide range of light outputs. Although purchase costs are higher than halogen lighting, these costs are offset in the long term by the durability of LED lights. At TRALERT® we stand for high quality and service, which is why we recommend LED lighting over halogen lamps because of the many benefits it brings.
