Amber Light Bar: Magnet or Bolts? Wiring and R65 Explained
A flashing amber bar for a tractor, telehandler or van raises three questions: will a magnet hold it, where does the power come from, and what do the markings mean?
The short answer: a magnet on a steel roof, bolts elsewhere, a feed of its own and R65 approval. PartsForMachines lists 113 lightbar products from LAP Electrical, Haztec and UTV Products.
Magnetic or Bolt-On: Will a Magnet Hold My Light Bar?
A magnet only holds if the roof will take one, so test it with a small magnet before you order. If it sticks firmly on a flat area, a magnetic bar such as the LBH244AC/MAG magnetic light bar can move between vehicles.
If the magnet slides off, or there is no flat area big enough for the base, choose a bolt-down bar. TITAN bars fix with four bolts, and their magnetic versions come in the 2ft length; the LBH244AC is the bolt-down twin. On a cab with no flat steel area or bolt-on space, send our team a photo of the roof before you order.
Where Should a Light Bar Take Its Power, and How Is It Switched?
Give the bar a feed of its own, switched from the cab, and fuse and wire it as the bar’s fitting instructions show. If you tap into the fog-light or main-beam circuit, the bar can only work when those lamps are on, which rarely suits a working machine.
Check the current draw when you choose the fuse and switch: the LAP-COMET955 slimline light bar draws 2.6A on 12V and 1.3A on 24V. Hurricane TITAN bars also offer three operating modes (simultaneous, left/right and front/back), so check how the mode is selected before wiring.
What Do R65, R10 and the Flash Pattern Options Mean?
R65 is the UN regulation for approving special warning lamps, so the mark shows the bar has been approved to that standard. Approval comes in classes: the Classic TITAN is Class I approved and the Cyclone TITAN Class II. If a site or customer specifies a class, match it. R10 is a separate approval for electromagnetic compatibility (EMC).
Patterns vary. The Tornado TITAN has one approved pattern, a double flash, while others offer several. The LAP-EQNX900 light bar also has the CAP168 airport pattern for airside work.
When Can Amber Warning Lights Be Used on the Road?
It depends on the country, so check the rules wherever the machine travels. In Great Britain, for example, a tractor or other motor vehicle with four or more wheels and a top speed of 25mph or less must show a flashing amber beacon on an unrestricted dual carriageway.
Vehicles first used before 1947 are exempt. Reflective tape helps a machine stand out, but it does not flash, so it cannot replace a beacon where one is required.
What Should I Check Before I Order?
- the roof: steel that holds a magnet for a magnetic base, or a flat area or bracket for bolt-down feet, and the length that fits
- the voltage: most bars here are 10–30V for 12V and 24V systems; ask our team to confirm it for Haztec and UTV Products parts
- the R65 approval and class your work calls for, plus R10 EMC approval
- the flash patterns and operating modes you need, including CAP168 for airside work
- the lens and cable: amber LEDs behind a clear lens or white LEDs behind an amber lens, and a cable long enough to reach the switch
If you are unsure which bar suits your machine, browse the Lightbars range or contact the PartsForMachines team by WhatsApp, telephone or email with the vehicle, its voltage and a photo of the roof.

Frequently Asked Questions
Which flash pattern should I choose?
Choose the one your site, client or employer specifies. If nothing is specified, a bar with several patterns keeps your options open: the LB242AC classic light bar offers single, double, triple and quad flash.
What is the CAP168 airport flash pattern?
It is a flash pattern for vehicles working airside at airfields. It is available on the EQUINOX, JUNO, LUNAR, Cyclone TITAN and Classic TITAN ranges, as standard or on request, so ask for it if you work at an airport.
Will one light bar work on 12V and 24V vehicles?
Usually. Most bars here are multi-voltage, 10–30V, so one bar suits both systems. On the COMET955, for example, the current halves at 24V: 1.3A against 2.6A at 12V. For Haztec and UTV Products parts, ask our team to confirm the voltage.
Why does my amber light bar look clear when it is switched off?
Many bars have amber LEDs behind a clear lens, so they look silver or clear when off and flash amber when working. Others, such as the LBH244WA/MAG, have white LEDs behind an amber lens, so they look amber all the time.
Is a white LED light bar the same as a warning light bar?
No. A driving bar such as the UTV244 white/amber light bar gives a 150W, 12,000-lumen forward beam with an amber daytime running light. A warning bar flashes to alert other road users. Check your country’s lighting rules before using a driving bar on the road.
Can I get a light bar that flashes amber and blue?
Yes, for vehicles allowed to show blue. The Cyclone TITAN range is R65 Class II approved in amber and blue, with amber/red and blue/red module options for recovery and emergency work. Check your country’s rules before fitting any colour other than amber.
Can I repair a damaged section instead of buying a new bar?
Sometimes. Haztec’s modular bars are built so a damaged module can be replaced without replacing the whole bar, and TITAN bars can take extra 3-LED and 6-LED modules. Send our team the bar’s part number and a photo to check what fits.
Will the light bar cable reach my switch?
Measure the run from the roof to the switch first. Hurricane and Classic TITAN bars have a 2.5 metre multi-core cable, EQUINOX bars a 3 metre cable and the LUNAR280 mini bar a 1 metre cable, so you may need to extend it.
How long a light bar do I need?
Measure the flat roof space first. Warning bars here run, for example, from the 280mm LUNAR280 mini bar to the 1828mm LBH724AC, and most ranges come in several lengths, so pick the length that fits.
