3.5 inch ZDM4 LED Auxiliary & Fog Driving Light System
For riders, darkness isn’t just the absence of light—it’s the presence of the unknown.
A hidden pothole, a sudden animal crossing, obscured road markings in pouring rain. Your standard headlights try their best, but for true safety and confidence on night rides, long tours, or off-road adventures, you need dedicated, intelligent illumination.
ZDM4 LED Auxiliary Spotlight – a compact 3.5-inch powerhouse engineered not just to add light, but to extend your vision, enhance your safety, and transform your after-dark riding experience.
ZDM4 is the result of listening to riders who demanded more: more distance, more control, and more reliability.

Feature Highlight: 1 Lux @ 230 Meters (Over 750 Feet)
1 Lux” is the standard unit for measuring illumination at a distance. It represents a usable level of light to identify an object clearly.
ZDM4’s precision-engineered reflector and high-output LED project this usable light an astounding 230 meters (over 750 feet) down the road.
Why It Matters for You: That’s longer than two football fields.
This massive reach grants you crucial extra seconds of reaction time.
Whether it’s debris, a stalled vehicle, or wildlife, seeing it from 230 meters away instead of 100 meters away can be the difference between a safe maneuver and an emergency.
Two Lights in One: Your Adaptive Beam Solution
Conditions change. Your lighting should adapt. ZDM4’s revolutionary dual-lens design eliminates the need to choose a single beam type.
Feature Highlight: Integrated White & Green Beams
Brilliant White Beam (16,000 Lux): This is your primary driving beam.
It delivers a intense, focused spot of pure white light (16,000 Lux), providing maximum contrast, excellent color recognition, and exceptional clarity for high-speed highway riding, country roads, and off-road trail blazing.
It complements your high beam perfectly, filling in the distance and periphery.
Specialized Green Beam (7,000 Lux): The game-changer for adverse conditions.
Green light has a longer wavelength that cuts through airborne particles like fog, mist, rain, and dust with less back-scatter and glare compared to white light.
This reduces eye strain for you and is often less blinding for oncoming traffic at a low angle. The green rubber border on the lens allows for instant visual identification of the beam mode.
Power is nothing without reliability. ZDM4 is built from the ground up to withstand the elements, vibrations, and the intense heat generated by high-power LEDs.
Overheating is the enemy of LED performance and lifespan. ZDM4 features a massive, finned aluminum heat sink that acts like a radiator, actively drawing heat away from the LED chips.
Combined with efficient internal design, this “Excellent heat dissipation performance” ensures the LEDs operate at optimal temperatures.
This prevents thermal throttling (dimming), maintains maximum light output hour after hour, and extends the functional life of the light far beyond cheaper, poorly cooled alternatives.
Corrosion-Proof Polycarbonate Bezel
Traditional aluminum bezels can pit, fade, and corrode over time, especially when exposed to road salt and weather.
ZDM4 utilizes a high-strength polycarbonate bezel. This material is incredibly impact-resistant, completely immune to corrosion, and maintains its finish without fading from UV exposure.
It’s a detail that ensures your lights look as good as they perform, season after season.
2x ZDM4 LED Auxiliary Spot Lamps: The core of the system.
“1-to-2” 3-Meter Wiring Harness with External Smart Driver: This is the brains and nervous system.
The harness integrates an external smart driver that ensures stable performance across a wide DC 9V-36V range (compatible with all 12V and 24V vehicles).
It includes two pre-wired connections for the lamps and a long run to the handlebars.
Dual Waterproof Handlebar Control Switches: Sleek, tactile buttons for total command.
Power Button (Light Icon): Simple on/off toggle. Press once for ON, press again for OFF.
Function Button (Lightning Icon): Activate safety flash modes. First press = Powerful Strobe Flash. Second press = Left-Right Alternating Strobe Pattern.
Safety Horn Flash Integration: A dedicated wire connects to your bike’s horn circuit.
When you press and hold your motorcycle’s horn for 1.5 seconds, ZDM4 lights will automatically trigger a dramatic emergency flash pattern, making you exponentially more visible in a critical situation.
Mounting Flexibility: Includes both handlebar clamp mounts and universal bumper/light bar brackets for maximum installation options.
Weatherproofing: Every critical cable connection in the harness is sealed with rubber O-rings, providing excellent protection against rain, spray, and dust (IP67-level connection security).
All Necessary Hardware & Hex Key: Everything you need for a clean install is in the box.
