GrizzLights Horizon Self-Stabilized EUC Headlight Watch the full demo: stabilization, beam modes, remote and real-world footageOr scroll down for detailed description Why EUC Headlights Fail Speed up and your light dives to the ground – exactly when you need to see ahead. Slow down and it shoots up, blinding oncoming riders. Stock headlights follow wheel pitch, creating visibility problems with every speed change. Climb a hill and your light aims at the ground directly beneath you. Descend and it shoots skyward while the road disappears into shadow. Fixed-mounted headlights can’t adapt to terrain changes. How Horizon Solves It Developed in collaboration with Michał Pietraszek, the original inventor of self-stabilizing EUC lights, Horizon uses a smooth BLDC motor to control the light angle in real-time, guided by dual-sensor intelligence, keeping your beam exactly where you need it. Stabilization Mechanism BLDC motor drive provides smooth, precise tilting movement across 45° range. This handles everything from aggressive acceleration to steep descents without hesitation. You won’t experience jarring corrections – just seamless and instant beam stability as you ride.Gyroscope tracks the wheel’s pitch angle in real-time, compensating instantly to keep the beam level during acceleration and braking. This eliminates the tilting headlight problem – your light stays pointed at the road ahead, not diving to the ground or shooting skyward. Lidar measures ground distance continuously, automatically adjusting beam angle on climbs and descents. When you hit an uphill, the lidar detects the changing distance and tilts the beam up to keep illuminating your path. On downhills, it adjusts the beam down.Smart sensor fusion algorithms prioritize the right input for each riding condition – gyro for smooth compensation on flat terrain and dynamic riding, lidar for terrain-aware leveling on hills. The lidar sensor sits on top of the light module, ensuring it remains unobstructed even with lower lift handle bumper setups. Automotive-Grade Light Ultra-Wide Low Beam Sharp beam cutoff prevents blinding oncoming traffic. Perfect for city riding and traffic situations where you need broad coverage without glare. The cutoff line is precisely engineered – your light illuminates the road ahead while staying below the eye level of oncoming riders and pedestrians. Long-Range High Beam Perfect for fast riding on dark roads and trails. The throw distance extends well beyond typical EUC headlights, giving you time to react to obstacles at speed. Very Bright DRL Two high-output diffused LED strips create a bright, continuous signature – no dotty LEDs.DRL is always on and dims slightly when low or high beam is active to maximize main beam output. It also acts as indicatior of device status and mode changes. Smart Remote Control Bluetooth finger-mounted remote puts complete control at your fingertips – literally. The wireless remote gives you instant access to beam adjustment, mode switching, horn, and quick flash – all without taking your eyes off the road or your hands off the wheel. Glove-Friendly Design Five distinct button shapes designed for tactile identification – you can tell which button is which by touch alone, even with thick winter gloves. The buttons are large enough to press reliably with gloved fingers and spaced to prevent accidental presses. Manual Beam Adustment Up/down buttons let you adjust beam angle across the full 45° range while stabilization stays active. Your preferred setting is saved automatically and persists across power cycles. Built-In Horn & Attention Signal Center button activates an audible horn through Horizon’s built-in beeper – effective for alerting cyclists and pedestrians on shared paths.Quick flash function gives you an attention signal when needed: double-click the right button to activate a rapid beam flash. Instant Mode Changes Left/right buttons switch between low and high beam instantly. Low beam activates the ultra-wide pattern with sharp cutoff for city riding. High beam engages the long-range pattern for dark roads and trails. Weather Protection Rainproof Construction: Every element and external cable entrance is sealed for wet weather use including rain, wet roads, splash, puddles, and snow. We’ve tested extensively in winter conditions – freezing rain, slush, and road salt spray.What to avoid: Submersion, pressure washing, and direct water stream. This isn’t a dive watch – it’s built for weather, not water sports. Compatibility Available now for most of LeaperKim EUC models. More wheels coming soon! Plug-and-play using the same 3.5mm mini-jack connector as your stock headlight. Works with stock setups and Grizzla Kit bumpers. Available NowVeteran / LeaperKim: Sherman S, Sherman L, Lynx, Patton, Patton S Coming SoonInMotion: P6Veteran / LeaperKim: Oryx, Lynx SNosfet: Apex, Aero, Aeon Why the wait?Newer models (Oryx, Lynx S, Nosfet family) use different architecture and beeper connection. Horizon Batch 1 would work as a light but without integrated beeper commands from the EUC – a safety concern we’re not willing to compromise on. The next PCB revision adds full support while maintaining all safety-critical beeper functionality. Warranty 12-month warranty covers actuator, sensors, and electronics under normal use.Not covered:• Water damage from submersion or pressure washing• Crash damage (conditions cannot be verified)• Normal wear and tear (scratches, scuffs)• Damage from unauthorized modificationsWe stand behind our work. If something fails due to a manufacturing defect or component failure within the warranty period, we’ll repair or replace it. Contact us at [email protected] with photos and description of the issue.
