Technical Support

Personalised technical support. This is what you can expect from TRALERT®. We have compiled the most frequently asked questions for you. Is your question not answered? Then please contact us.


If your ordered products are delivered from stock and you have ordered them before 15:00, you can expect the lighting the next day. 

TRALERT® lighting is reliably and accurately shipped with DHL Parcel.

In this case the products must be shipped from subwarehouses of TRALERT®. The average delivery time is 5-10 days. If this is not the case, you will be informed in due time. 

If you have ordered a bulk order of products that are in stock, we will deliver them the next day. If the order cannot be delivered to you in its entirety the next day, we will send it in a partial delivery or in consultation at a later date.

A customised order has various delivery times. Simple adjustments such as cable lengths and connectors are made by our technical department in our technical room. If your customization requires more modifications, we need to plan these during production. For this, we recommend contacting the TRALERT® product specialists.

Connecting lighting

The wiring diagram for your purchased lighting system is always included in the packaging. Here you can find how to connect the lighting. 

If you have lost your wiring diagram, you can find all the wiring diagrams here. If you still cannot find what you are looking for, please contact our technical department. 


If your light flashes, this can have various causes. Often, an unstable light signal is caused by an incorrect connection, incorrect voltage or Can-Bus.

There can be various reasons why the LEDs in your lamp are not all lit up. For example, the light may not be connected correctly or your vehicle may be detecting the light incorrectly. 


The guarantee on TRALERT® lighting is different and can be found on the packaging or product page. Fristom lights have a 2 year warranty. LED Autolamps have a warranty of 3-5 years. TRALERT® lighting has an average of 3 years.  

If your lamp is not working properly, we will be happy to work with you to find out the cause. If it is a technical defect to internal components and your lamp is within the warranty period, we will gladly exchange it for a working one. If the lamp has failed due to a faulty connection, this is not covered by the guarantee.

You return a product by sending the product back and the return form to add.
