Welcome to Linear Electronic Design: The creator of the original LED Adaptor Module.

For use with TRAILERS, CARAVANS & CAMPERS with flashing LED trailer lights.

Why do my trailer lights flash?
European 4WDs have an in-built diagnostic system that will cause the LED trailer lights to flash or pulse continuously as the car’s onboard computer attempts to detect the trailer.

What are the benefits of Linear Electronic Designs LED Adaptor Module?
The use of our LED adaptor module ensures that the vehicles on board computer recognises that a trailer is connected so that the rear parking sensors are disabled and the cars safety features (such as traction control and brake force distribution) are adjusted accordingly. This will stop your trailers LED lights flashing and enable you to tow your trailer more safely!

Features of our portable module include:
  • Rugged, water resistant construction rated to IP66
  • Portable
  • No installation costs
  • Transferable between trailers
  • Wide operating temperature range -40C to +85C
  • High efficiency
  • Slim Profile
  • Combined trailer plug adaptor (e.g. flat to round, or round to flat, or small round to large round etc)

We also offer modules that can be installed into the trailer wiring or within the vehicle itself that would allow the trailer to be directly plugged into the vehicle without adaptors (some installation is required).
