Strobe or beacon for a tractor?
A beacon shines all around (360°) and one is enough, usually on the cab roof. A strobe is flat and shines mainly in the direction it faces. That is why it is chosen where a beacon will not fit or would be obscured – e.g. by a front loader, a mounted implement or a low roof in a farm building. To make the signal visible from every side, several strobes are fitted.
You can read more about the types of lamps and their colours in the article Roof beacons and strobes – warning lamps.
When a tractor may have its warning light switched on
Under Article 54 of the Polish Road Traffic Act (Prawo o ruchu drogowym), yellow (amber) flashing signals are emitted by a vehicle carrying out cleaning, repair or upgrading work on the road, and by a vehicle which, due to its design, load or behaviour on the road, may pose a risk to road safety. For a tractor, this most often means travelling with implements wider than 2.55 m, working with a machine on the road, or standing after a breakdown in a place dangerous to others.
Without such a reason the strobe should be switched off – a tractor pulling an ordinary trailer does not use warning lights. Only amber is suitable for a tractor; blue flashing lights are reserved for emergency vehicles. We describe the details in the guide Magnetic warning beacon – how to choose and when you may switch it on.
Where to mount a strobe on a tractor
- At the front – on the cab frame, above the windscreen or on a guard, so that neither the front loader nor the machine obscures the lamp.
- At the rear – on the rear cab frame or on the mudguards, above the mounted implement.
- On the sides – with wide implements it is worth adding lamps facing sideways, so the tractor is also visible at junctions.
The lamp is bolted to a flat, rigid surface. Before drilling, check that the cable can be routed to the cab without sharp edges or places where it could chafe.
Which strobe to choose for a tractor
All the lamps below work at 12 V and 24 V, so they suit both tractors and machines with a 24 V system.
- LDO 2780 (XA2) – 6 LEDs, 4 flash modes and 2 brightness levels: day and night. Power 12 W, IP68 sealing. A good choice for the front and rear of the cab.
- LDO 2675 – compact lamp with 3 LEDs, dimensions 96 x 28 x 20 mm, power 4.2 W, IP68. Fits on narrow frames and mudguards.
- LRD 3068 – 1200 lm (5600 K) work lamp with a built-in amber strobe (4 flash modes). One device instead of two: it lights the work area and warns others. Single-bolt mounting.
If there is room for a beacon on the roof, you can choose a pole-mounted lamp – e.g. LDO 2665/F (24 LEDs, flashing mode 2.1 Hz) or LDO 2661 for a DIN Ø24 pole. You will find all models in the Amber warning lamps category.
A warning lamp used on public roads must be approved to ECE R65, and an LED lamp additionally to ECE R10 (electromagnetic compatibility). All warning lamps in our shop meet both requirements.
Connecting the strobe
The strobe is connected to the electrical system via a separate switch in the cab, so that the driver can switch it on only when it is needed. Several lamps can be powered from one switch. LED lamps draw little current – the LDO 2675 has a power of 4.2 W and the LDO 2780 12 W – so several units do not overload the tractor's electrical system.
Frequently asked questions
How many strobes does a tractor need?
Enough for the signal to be visible from the front, the rear and – with wide implements – the sides. This means at least one lamp at the front and one at the rear, and with wide machines also side lamps.
Does a 12 V strobe suit a 24 V tractor?
The lamps described above have a 12/24 V supply, so they work on both systems. For other models, check the voltage in the technical data.
Can I fit a blue strobe on a tractor?
No. Blue flashing lights are reserved for emergency vehicles. For tractors and agricultural machinery, choose amber lamps.
