Trailer Lighting Regulations

 

Bringing your trailer out of retirement? Building your own trailer? You're going to need to know the trailer lighting regulations as it's a legal requirement for trailers to have the correct lights, markers and reflectors.

Here's our guide based on The Road Vehicles Lighting Regulations 1989...

Trailers built before September 30th 1990

All trailers must have two red side lights, two red stop lights, two red triangular reflectors, an illuminated number plate along with amber indicators designed to flash between 60-120 times per minute

Trailers built after September 30th 1990

Must also be fitted with front white reflectors.

Trailers more than 1.3m wide

Must also have atleast one red fog lamp.

Trailers more than 1.6m wide

Must also have front position white markers/lights.

Trailers longer than 6m (excluding drawbar)

Must also have red/white side markers. So side marker lights are only required by law if the trailer is above 6m in length.
