Bicycle lamp type-approval tests

Approved quality enhances safety

The German Road Traffic Licensing Regulations (StVZO) stipulate that bicycles must have type-approved lamps in order to be used on public roads § 67 (1).
DLG is a Technical Service designated by the German Federal Motor Transport Authority (Kraftfahrt-Bundesamt - KBA) and licensed to conduct type-approval tests of vehicles and vehicle parts. In this capacity we offer manufacturers of bicycle lighting and light-signalling devices comprehensive services and support.

We provide support in various ways:

  • We offer advice on the manufacturer‘s initial assessment which is made by the German Federal Motor Transport Authority (Kraftfahrt-Bundesamt - KBA)
  • We assist you in obtaining the type-approval (ABG) which is required by § 22a of the German Road Traffic Licensing Regulations (StVZO) in conjunction with the Vehicle Parts Ordinance (FzTV).
  • We guide you through the homologation processes for a wide range of technical equipment – including basic vehicle lamps, complex lighting systems with daytime running lamps and high beam functions, regular dynamo-based rear position lamps with/without capacitor powered LED front position lamp and special e-bike rear position lamps with integrated retro-reflecting device and brake lamp function. The lamps can be powered by a dynamo, batteries, rechargeable batteries or the on-board e-bike network.

We conduct regulated tests that are required for obtaining the type-approval (ABG)

    • Testing coefficient of luminous intensity
    • Testing water tightness (immersion test)
  • TA 18a tests for reflective strips on bicycle tyres
    • Testing coefficient of luminous intensity
  • TA 23 tests for head lamps on bicycles
    • Testing illuminance distribution
    • Testing glare-free performance
  • The following parameters are tested to the following Technical requirements: TA 2 General Requirements, TA 3 Terms and Measurement Rules, TA 4 Structural Requirements, TA 5 Structural Testing
    • Water tightness (IP test)
    • Corrosion resistance
    • Fuel resistance
    • Temperature resistance
    • Fastening and setting systems and devices
    • Electrical connections
    • Battery or rechargeable battery
    • Dynamo
    • Capacitor powered LED stand light
  • The accompanying documents / documentation
  • All type-approved parts must bear a type-approval mark as stipulated by the Vehicle Parts Regulation (FzTV)  K 1234.
