Many trailer dealers ask the question: why choose LED rear lights for a trailer? In this blog, we will answer this question. We will discuss what to consider when selecting new LED rear lights for your trailer and explore the advantages and disadvantages of LED rear lights. Finally, we will share our vision on LED lighting for trailers and explain why we believe LED lighting is the future for trailers and towed trailers.

What to consider when choosing new LED taillights for your trailer?

Quality LED taillights for your trailer are essential, not only for you but also for other road users. Good LED taillights are visible from a considerable distance. This can be useful in adverse weather conditions, such as rain or storms. In some situations, you may have to drive on dark roads around forests or natural areas. Even in these situations, it is safest to opt for LED taillights on your trailer that are visible from a distance.

Do you want to equip your trailer with quality LED lighting? TRALERT® offers a suitable lighting solution for every need in its product range. Feel free to browse the product range on the dealer portal. If you have technical questions about the products, you can always ask our technical experts, who can be reached by phone.

Pros and cons of LED taillights on a trailer

When you decide to equip your trailer with LED lighting, this comes with advantages and disadvantages. The overview below will help you understand what to expect when you replace halogen lighting with LED taillights.


  • Design: LED lights feature small, bright light bulbs. These are smaller in size than halogen lights. In most cases, LED taillights feature a sleeker design than halogen lights.
  • Energy consumption: LED lights consume 75% less power than halogen lights and 85% less than incandescent lights.
  • Durability: In terms of durability, LED taillights are by far the best choice. Where a halogen taillight lasts about 500 hours (12.5 working weeks), the LEDs from a good set of LED taillights last about 50,000 hours.
  • Waterproof: TRALERT® LED taillights have at least an IP67 certificate. This means that the LED taillights are splash-proof and can therefore also be used in the rain.
  • Several connectors available: At TRALERT®, the LED taillights are available with different connectors. For example, the LED taillights are available with a 5 PIN's Bayonet Connector, 6 PIN's Bayonet Connector and a 7 PIN's AMP Connector. Furthermore it is also possible to order the LED taillights with cables of different sizes, including the 0 - 50 cm cable, 51 - 100 cm cable and the 100cm+ cable.


  • Pricing: The only disadvantage of LED taillights for trailers is the purchase price, which in many cases is higher than comparable halogen taillights. In another blog, we have discussed the purchase price of LED work light compared to a halogen work light. This showed that buying an LED worklight would be the most advantageous option over time.
  • Canbus issue: Due to the low amperage consumption of LEDs, this can cause interference with the CANbus of modern vehicles. This can result in flickering lights and, in the worst case, complete lighting failure. To prevent this, TRALERT® offers various canbus solutions and provides Canbus-proof solutions.

LED tail lights for trailers: a trend or the future?

When we weigh the advantages of LED taillights for trailers against the disadvantages, the choice is easy. LED taillights are, in our opinion, perfectly suitable for trailers. The only disadvantage is the purchase price. However, this disadvantage can be neglected because the number of burning hours of an LED taillight is much higher than that of a halogen taillight.
