The Exposure EX4 is a compact, seriously powerful driving light designed and manufactured in the UK by Exposure Lights.

And now there is another major reason to choose it.
The Exposure EX4 has been independently tested by TÜV Rheinland Kraftfahrt GmbH in Germany and formally granted approval under UN ECE Regulation No. 149 by the United Kingdom Vehicle Approval Authority.

Exposure chose TÜV Rheinland as the independent technical service responsible for testing the EX4.
The official test report confirms that the EX4 complies with the applicable requirements of UN ECE Regulation No. 149 as a driving-beam headlamp.
The testing went far beyond simply checking light output.
The EX4 was assessed for photometric performance, light colour, construction, vibration resistance and performance stability. The report confirms that the light continued to operate correctly despite vibration and remained within the permitted photometric tolerances.
Following testing, there was also no distortion, deformation, cracking or change in colour of the lens.
At the heart of the EX4 are four CREE XHP35.2 LEDs, producing a combined output of 4,300 lumens.
The EX4 uses 8-degree collimated optics to create a focused driving beam designed to throw useful light further down the road rather than simply creating uncontrolled glare.
With a light temperature of approximately 5700K, the output is a crisp bright white, ideal for improving visibility on dark roads and unlit routes.
Exposure Lights are designed and manufactured in the UK by Ultimate Sports Engineering Ltd.
Exposure’s lighting heritage comes from decades of development in demanding environments including cycling, endurance racing and rallying, and that experience has been carried directly into its AutoMoto lighting range.
The EX4 uses a robust aluminium housing, toughened glass lens and intelligent thermal management to deliver reliable performance in demanding conditions.
The official Exposure technical documentation records the EX4 at 4,300 lumens, 445g, IP69K, 5700K and 3A at 12V, together with its 7-year warranty and construction details.
The Exposure EX4 is fully compatible with the HEX ezCAN, allowing the lights to integrate with the motorcycle’s existing controls on supported bikes.
Depending on the motorcycle and configuration, an ezCAN can provide features such as adjustable auxiliary light brightness, high-beam activation and other programmable lighting functions without adding unnecessary switches to the handlebars.
For the easiest installation, take a look at our A Bike Thing Exposure lighting bundles, where we combine the correct lights, controller, wiring and mounting hardware for specific motorcycles.
There are plenty of powerful auxiliary lights on the market, but outright lumen figures only tell part of the story.
The EX4 combines serious light output, compact dimensions, British manufacturing, rugged construction and now independently verified UN ECE approval.
For riders looking for a premium driving light that delivers proper real-world performance without huge pods hanging from the motorcycle, the Exposure EX4 is a superb option.
