A tractor needs several kinds of lighting: road, work and warning lighting, and often lighting for machines and the trailer too. We have collected them in one place, with example lamps and links to detailed guides.

Replacing the lights on your trailer or kitting out a new one? We explain how many functions to choose, what to watch when mounting, and what to do when an LED indicator flashes too fast.

A strobe is a flat flashing lamp bolted wherever you choose on the tractor – on a mudguard, cab frame or guard. We explain when you may switch it on, how many to fit and which model to choose.

White at the front, red at the rear, amber on the sides – marker lamp colours come from the regulations, not from taste. Yet some drivers treat marker lamps as a style statement. We explain the rules and the phenomenon.

Halogen or LED, how many lumens, IP69K, 12 or 24 V and where to mount the lamps on a tractor – we explain what matters when choosing a work lamp and show specific Horpol and WESEM models.

Spraying after dark or early in the morning gives better agronomic conditions and is required by many plant protection product labels. Without nozzle lighting, however, you cannot see the spray cone or clogged nozzles.

Beacon or strobe – how do they differ and when are they required? An amber warning lamp may only be switched on in specific situations; otherwise you risk a fine. We explain types, colours and mounting rules.

A magnetic beacon goes on the roof without drilling and plugs into the cigarette lighter socket. We explain when you may switch it on and how models with 24 and 48 LEDs differ.

We tested four cheap LED work lamps with an integrating sphere. Declared power: from 27W to 126W. Measured: from 7W to 33W. See the measurement results and what we found inside a dismantled lamp.

The regulations specify not only which lights a trailer must have, but exactly where to mount them. Maximum distances from the edges, minimum spacing, permitted heights – the exact figures from the regulation in one place.

A tractor, trailer or machine going out onto a public road must meet specific lighting and marking requirements. What is always mandatory, what depends on vehicle width, and when do the regulations allow an exception?

Retrofitting daytime running lamps requires a correctly approved lamp, the right mounting height and spacing, and proper wiring. All the regulatory requirements in one place.

The regulations specify exactly which lighting every trailer must have and which depends on its width, length or mass. I have collected the requirements in one place – with exact thresholds and registration dates.
