Resistance

What is resistance?

Resistance is the degree of resistance that current encounters in a circuit. All materials offer some degree of resistance to current. They can be divided into two broad categories, namely: conductors and insulators. The higher the resistance, the lower the current. The lower the resistance, the higher the current. The voltage across the resistance is determined by the colour of the LED.

Connecting LED resistors to semi-trailers, semi-trailer or vehicles

Because LED requires many times less current to burn than regular lighting, the vehicle may think the light is broken. As a result, you will get an error message on your dashboard or your indicators will start flashing faster. This can be solved by using resistors. A resistor ensures that your semi-trailer lights or other vehicle lights work correctly. Each vehicle has a different connection. That is why there are 12 volt and 24 volt resistance connections.

Mounting the LED resistor

Connecting a resistor is quite simple. It involves connecting resistors between the LED lighting and the vehicle where you want to place it. Since there is a possibility to supply resistors with cabling, you can more easily place them between the existing wiring. It still happens that LED lighting from your semi-trailer wants to interfere with the connection when connecting. This is because LED requires much less energy than halogen lighting. By connecting a resistance, you will no longer suffer interference.

There may also be a problem with the vehicle's Canbus. For example, if you equip your semi-trailer with LED lighting. By placing resistors between these, the error message will disappear and the LED lighting will work properly.

To determine which resistors best fit your vehicle, semi-trailer or semi-trailer , it is important to determine which connection and voltage it should meet. Not sure? Then feel free to contact TRALERT® technical support.
