Extended Product Information

FAQs

Can I use this on a standard 12V car battery?

No, this unit is specifically designed for 24V electrical systems and will not function correctly on 12V systems.

What is the mounting method?

The unit uses a secure, bolt-on mounting configuration suited for flat panel surfaces.

Are these lights waterproof?

The housing is built to be weather-resistant for automotive use, but proper sealing of the open cable ends during installation is essential for longevity.

What are the exact dimensions?

The indicator measures 80mm in width, 80mm in height, and 34mm in depth.

Does this light meet safety standards?

Yes, it is manufactured to meet or exceed OE standards and is ECE R6 compliant.

Troubleshooting

Indicator fails to illuminate

Verify that the vehicle voltage is exactly 24V and check the wiring connections at the open cable ends for loose contact or polarity issues.

LEDs flicker intermittently

Check for moisture in the cable connections or verify that the mounting bolts are tightened sufficiently to maintain a stable ground connection.

Pros and Cons

Pros

  • High-intensity LED output for superior visibility
  • Sturdy construction designed for long-term reliability
  • Compact form factor fits various vehicle configurations
  • Certified to international ECE R6 safety standards

Cons

  • Strictly limited to 24V electrical systems
  • Requires professional wiring due to open cable ends
  • Not compatible with standard 12V light housings

Setup, Compatibility & Care

Installation requires knowledge of 24V vehicle electrical systems. The light features open cable ends, meaning the installer must perform proper terminations—such as heat-shrink butt connectors or automotive-grade quick-disconnects—to ensure moisture resistance. Before installation, confirm that the mounting surface can accommodate the 80mm bolt pattern. To maintain performance, periodically wipe the lens with a soft, non-abrasive cloth to remove road grime and ensure maximum light output. Avoid using high-pressure washers directly against the cable entry points to prevent water ingress.
