German StVZO-certified products encompass not only automotive and motorcycle components but also bicycle lighting systems—including front headlights and rear taillights. To ensure road safety, Germany’s Federal Motor Transport Authority (KBA) has established specific safety standards for bicycle lights under Section §22a TA23 of the StVZO. This regulation outlines in detail the mandatory safety testing requirements for such equipment.
These regulatory provisions form a critical part of German road traffic safety law, governing key performance aspects of bicycle lights such as beam pattern and light intensity distribution. The purpose of StVZO certification is to guarantee that bicycle lighting provides adequate illumination during nighttime or low-visibility conditions while preventing glare or hazards to other road users.
Several key compliance points must be observed to meet German regulatory requirements:
Cut-off Line Design: StVZO-certified bicycle lights must feature a distinct cutoff line to prevent light scatter and avoid dazzling oncoming road users. This design minimizes glare for oncoming cyclists, thereby reducing safety risks during night riding.
Beam Pattern Standards: The beam pattern must conform to standard illumination requirements, preventing excessive concentration of light in a single spot. Light distribution should be evenly spread across the front of the wheel, with brightness gradually increasing from near to far—ensuring sufficient width at close range and adequate reach at a distance.
No Flashing Function: StVZO-certified lights are prohibited from having flashing modes to avoid distracting other road users.
Low Battery Indicator: Lights must include a low battery indicator, allowing riders to monitor power status and take timely action. During testing, the light is powered by new batteries and operated continuously for one hour before evaluation; no low battery warning may appear during this period.
Mounting Height: The mounting height must be between 400–1200 mm to ensure effective road illumination while preventing excessive height that could direct light into oncoming traffic.
Switch Design: The light may feature automatic or manual controls but must not be obstructed in any way to guarantee proper functionality.
Color Temperature Requirements: StVZO-certified lights typically have a color temperature not exceeding 5000K, ensuring a warm tone to reduce visual fatigue while providing better penetration in various conditions.
Waterproof Rating: Many StVZO-certified lights offer high waterproof ratings, such as IPX6, enabling reliable performance in adverse weather.
Charging & Installation: Some StVZO-certified lights use Type-C charging ports for fast charging and feature user-friendly mounting systems—such as universal Garmin-compatible bases—for quick installation, removal, and cross-device compatibility.
Certification Process:
The StVZO certification process consists of: type testing + factory inspection + type approval.
The certification timeline is approximately 12 weeks, requiring three samples.
StVZO-certified bicycle lights deliver professional, safe lighting solutions. For those who frequently ride at night or in low-visibility conditions, choosing lights that meet StVZO standards is essential.
