Overview
The ARB AR21S is a 7-inch round LED driving light with a spot beam, made by ARB 4×4 Accessories. It is universal fit rather than built for one vehicle, and it mounts to bull bars and traditional driving light mounting points, so it suits off-road vehicles that already carry those brackets.
ARB began developing the light in 2009 as an alternative to LED light bars. The brand’s engineers wanted a driving light that works with current bull bar designs and standard mounts, and that could be a legal fitment, which ARB notes light bars often are not in many states. Many ARB customers pair a spot light with a spread light to handle varied off-road conditions, and the AR21S is the spot half of that pairing, built to penetrate longer distances than a broad flood pattern.
Key features
- Round 7-inch LED driving light with a white lens
- Spot beam pattern for penetrating longer distances
- Bracket mounting type for bull bars and traditional driving light mounting points
- Designed by ARB as a legal-fitment alternative to most LED light bars
- Sold as a single light
Wiring and mounting considerations
Driving lights add useful reach on trails and rough roads, but their output depends on how they are aimed and how steady the mount is. A spot pattern concentrates light down the track, so setting the angle to match your usual speeds makes a practical difference. Brackets that flex under load can throw the aim off, so check the mount hardware after rough runs.
Electrical setup matters as much as the mount. Driving lights draw meaningful current, so a fused relay with its own feed from the battery protects the vehicle wiring and keeps the lights from dimming other systems. Use wire sized for the load and route it away from moving suspension parts and sharp edges.
- Re-check bracket bolts after the first few trail runs
- Aim the spot beam at your typical driving distance
- Use weatherproof connectors at every splice
- Keep the switch within easy reach of the driver

Vehicle fitment
The AR21S is universal fit, so it is not matched to a specific year, make, model or trim. Its bracket mount suits bull bars and traditional driving light mounting points. Check that your bumper or bull bar has matching mounts before ordering.
Light bars and other mounting styles use different designs and are not covered by this bracket mount. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Mount the bracket to a bull bar or driving light mount, then aim the spot beam. Wire the light through a fused relay so it runs on its own circuit. Check local road-use rules before using driving lights on public roads, since rules vary by state.
What’s included
The item is sold as a single light.
Not included: Wiring, switch and relay are not included with the light.
