EXPERIENCE CENTRE
At TRALERT®, you’ll find everything you need for your trailer lighting. However, we understand that it’s difficult to judge the quality of light from a photograph alone. So please do pop into our Experience Centre to see the lights for yourself. You are very welcome to visit by appointment at a time (during opening hours) that suits you best. To ensure you receive the full attention and assistance you deserve, we ask that you book an appointment.
Trailer lighting supplier for the professional
TRALERT® supplies trailer lighting to professionals who require reliability, continuity and technical support. As a wholesaler of trailer lighting and a supplier to professionals, TRALERT® offers scalable solutions for both small series and large-scale production. Every day, we work with organisations that are not just looking for lights, but for a supplier who can help devise complete lighting solutions.
For buyers, a stable product range is essential. That is why TRALERT® supplies a wide range of rear lights for trailers, connectors, wiring harnesses and accessories that meets the day-to-day demands of the market. With a clear product structure, consistent specifications and support in product selection, we help you respond quickly to your customers’ needs.
Vehicle construction and bodybuilding
For vehicle builders and bodybuilders, what matters most is the combination of technical compatibility, ease of fitting and consistent quality. TRALERT® provides support in selecting the right lighting for each vehicle type, application and connection. Whether it’s standard solutions or project-specific designs: we contribute ideas based on practical experience.
Our range of trailer lighting for professionals
TRALERT® offers a complete range of trailer lighting for professional applications. This allows you to purchase individual components or opt for a comprehensive solution in which lighting, cabling and connection materials are fully compatible.
Our range includes, amongst other things, LED rear lights, marker lights, side marker lights, licence plate lights, fog lights, reversing lights, reflective solutions, wiring harnesses and connectors for trailers. For many applications, it is precisely the combination of components that determines the reliability of an installation. That is why we provide support not only at product level, but also in system selection.
For 12V applications, various wiring harness configurations and connector options are available, including 5-PIN, 6-PIN, 7-PIN and 8-PIN variants. Connector families such as SuperSeal, Deutsch connector, Aspöck ASS2 and Hella Easyconn often feature in practical applications. With 24V systems, bespoke solutions are even more important, partly due to differences in trailer length, light functions, side marker lights, main cable, connection boxes and the required connections.
Suitable for series production
For customers working with repetitive surface mounting or recurring vehicle configurations, we support them with products and assemblies suitable for structural purchasing and serial processing.
Wide choice in 12V and 24V
From light trailers to professional trailer solutions: TRALERT® supplies lighting components and matching cabling for a wide range of voltage and application requirements.
This is why professionals choose TRALERT®
In practice, this involves technology, product availability and support when it matters most. This is how we help our partners make the right choice. We do this, amongst other things, through a knowledge base full of expert articles. Such as a guide to a complete trailer system or blogs offering solutions for interference with trailer lighting.
Technical expertise and support
TRALERT® combines product knowledge with practical understanding of vehicle lighting. We support questions about functions, connections, compatibility and surface mounting of complete lighting systems. This is particularly relevant for customers who need to make the right choice quickly or work with more complex vehicle configurations.
Focus on certified and reliable solutions
Correct specifications and reliable product information are indispensable for professional applications. This is why TRALERT® is focused on lighting solutions that match market requirements and the practice of professional mounting and replacement.
Efficient procurement for professionals
We understand that buyers and technical teams need speed. Through a wide product range, clear product specifications and product selection support, we help procurement processes and project requests run more efficiently.
Many customers are not looking for a single supplier, but for a partner who thinks along with them about the total solution. This is where TRALERT® makes the difference. We look not only at the light, but also at the connection, wiring harnesses, connector, application and use in practice.
Complete trailer lighting set
TRALERT® offers various ready-to-fit LED lighting kits for trailers, ranging from basic sets to highly comprehensive professional configurations. These kits are often designed to be plug-&-play, including wiring harnesses and connectors, to simplify installation.
- Standard set: A complete basic solution with wiring harnesses, two rear lights, licence plate lights and white marker lights for the front.
- PRO set: Expanded configuration with modern LED rear lights, marker lights, licence plate lights, side marker lights and a complete wiring harness.
- PRO+ set: The most comprehensive solution, suitable for larger and professional trailers, including additional features such as work lights, a third brake lamp and supplementary marker lights.
Trailer lighting as a system, not as a standalone product
Good trailer lighting rarely starts with a single product. In practice, it’s all about the right combination of light functions, connectors, cable lengths, mounting points and vehicle type. Particularly in professional applications, a system-oriented approach prevents interference, delays and unnecessary replacement costs.
TRALERT® therefore also provides support in addressing the requirements behind the product. What functions are required? Which connector is used? Is side marking required? Should a trailer wiring harness be standard or bespoke? And which combination of lighting and connection components best suits the application?
Expertise and support for trailer lighting
Are you looking not only for products, but also for information on the regulations governing trailer lighting or technical explanations? TRALERT® has a knowledge base containing interesting and up-to-date articles.
We therefore invite you to read our comprehensive guide to connecting trailer lighting for more information on regulations, mounting, connections and the correct lighting configuration for each application.
