SITIS Officially Launches SIRIUS 10 Smart Lighting System, A New Generation of Smart Optics for Two-Wheelers
Chongqing, September 20, 2026
At 10:30 a.m. on September 20, during the 24th China International Motorcycle Trade Exhibition (CIMA), SITIS officially unveiled its 10‑generation flagship smart lighting system — SIRIUS 10 at Booth 6T13, Hall N6, Chongqing International Expo Center. Following SIRIUS 8 and SIRIUS 9 that maximized optical performance, SIRIUS 10 marks a cross‑generational leap from a simple lighting fixture to a full‑fledged perception‑enabled intelligent system. It shifts two‑wheeler lighting competition from pure optical performance to perception‑decision‑execution intelligent capabilities.
Founded in 2016, SITIS is a core lighting supplier for global renowned brands including Honda, CF‑Moto, Loncin, VinFast, Yadea, Segway‑Ninebot and NIU. Over ten years, SITIS has iterated ten generations of the SIRIUS platform. As traditional metrics “wider, brighter, farther” approached physical limits, SITIS re‑imagined what motorcycle lamps can do: lights should not only emit light, but also perceive surroundings, make judgements and adjust dynamically. Earlier this March, cooperating with Ouye Semiconductor and Crystal Opto, SITIS brought automotive‑grade ADB adaptive lighting to mass‑produced two‑wheelers with the world’s first mass‑produced AI smart headlight, laying solid technical foundation for SIRIUS 10.
Four‑dimensional Upgrade: Performance, Refinement, Perception & Intelligence
1. Elevated Optical Performance as Intelligent Foundation
SIRIUS 10 does not compromise basic lighting for smart features, setting new industry benchmarks for optical performance.
Ultra‑wide coverage: 180‑degree horizontal field of view, illuminating up to six traffic lanes, eliminating the common “bright‑center‑dark‑sides” defect and clearly revealing curbs, guardrails and pedestrians.
Longer reach: Maximum effective beam distance reaches 220 meters, +40 meters versus predecessor. At 60 km/h, it delivers an extra 2.4 seconds for hazard avoidance.
Higher luminance: Peak intensity hits 110 000 cd (+25% generation‑over‑generation), matching lighting performance of D‑segment luxury passenger cars, maintaining clear vision even during oncoming traffic encounters.
Speed‑adaptive brightness: Lamp output automatically adjusts according to vehicle speed — softer at low speed to avoid glare, brighter and farther at high speed.
2. Revolutionary Perception‑Driven Closed‑Loop Intelligence
Unlike previous generations with fixed beam patterns relying on manual driver input, SIRIUS 10 establishes a complete perception‑decision‑execution loop, enabling the lamp to “see and think”. Key intelligent functions include:
Weather adaptation: Dual‑color light mode enhances penetration in rain and fog and suppresses scattered glare.
Width adaptation: Dynamically adjusts horizontal illumination width for urban roads or open highways.
Trajectory‑following lighting: Light footprint follows vehicle path in bends and mountain roads.
AI recognition for pedestrians & oncoming vehicles: Intelligently masks high‑beam zones for detected road users. High‑beam can stay active without dazzling opposite‑side traffic.
Pitch‑adaptive beam height: Compensates lamp elevation under passenger load, cargo weight or slope climbing to prevent upward glare or insufficient forward reach.
Bank‑angle‑based corner compensation: Automatically fills dark inner‑corner zones when the motorcycle leans, upgraded HIAS cornering lighting improves safety during leaning turns.
3. Platform‑oriented Modular Architecture with Four Variants for Full‑range Vehicle Types
Built on unified platform hardware, SIRIUS 10 comes in four variants: 10 Mini, 10 Smart, 10 Premium, 10 Max, covering lightweight e‑motorcycles, large‑displacement ICE bikes and maxi‑scooters. - 10 Mini: Ultra‑compact dual‑function module, cost‑effective, safe and energy‑saving. - 10 Smart: Compact intelligent unit supporting multi‑scene smart features. - 10 Premium: Balanced performance‑styling solution for most mainstream OEM applications. - 10 Max: Top‑tier flagship delivering full‑set lighting and interactive capabilities.
The platform supports early‑stage styling co‑development. Hardware natively satisfies China 3C, EU E‑Mark and other global homologation standards, cutting OEM development cost and lead‑time for multi‑region markets.
4. New “Radiance” Taillight & Signal Lamp Series for Premium Aesthetics
Alongside SIRIUS 10 headlight system, SITIS launches the new Radiance taillight & signal lamp product line. Conventional taillights use discrete LED dots with visible grain, uneven seams and stray light. The Radiance series adopts optical‑grade light‑guide material, high‑precision micro‑optics and curved‑surface integrated molding. It transforms discrete point light sources into gem‑like uniform surface illumination. Exposed light sources are eliminated for premium appearance, integrating TAIL / STOP / turn‑signal functions, balancing styling and regulatory compliance.
Full‑stack In‑house R&D and Comprehensive Technology Portfolio
SIRIUS 10 is fully self‑developed with 15 patents including 5 invention patents, covering optical structure, electronic control algorithms and industrial appearance. SITIS maintains high‑intensity R&D investment with compound annual growth rate above 90%. The company has built a comprehensive two‑wheeler lighting technology portfolio: AFS, ADB, ALS, ISD surface‑illuminated taillight, DLS digital lighting system and GLS global lighting system.
Following its domestic premiere at CIMA Chongqing, SIRIUS 10 will make its overseas debut at EICMA Milan for global OEM partners. Supported by Hangzhou R&D center, Zhuhai mass‑production base and planned Vietnam supply‑chain facility, SITIS provides full‑cycle services including optical concept design, prototyping, validation and serial delivery for worldwide clients.
