  • Product information



    Modern vehicle accessories of different types now frequently carry an "E" approval mark valid throughout Europe. This "E" mark, which is made up of a combination of letters and numbers, is clearly displayed on the product and shows the application tested, the country in which testing was carried out and, where appropriate, the vehicle type to which approval applies. EC type approval for exhaust systems, for example, are always issued for a specific vehicle type, whereas in the case of lighting, they apply to an entire group of vehicles, e.g. motorcycles.
    This certification mark is the sole proof of legality stipulated by law, i.e. no written report or entry in the vehicle documents by TÜV (German Technical Inspection Association) is required. However, when it comes to installing accessories, the relevant guidelines of the Road Traffic Licensing Regulations (StvZO) must always be observed.
    At at a roadside check or a TÜV vehicle inspection, the registered keeper is only required to show the "E" mark. It is then up to the official in charge whether to check the mark with the Federal Motor Transport Authority (KBA) in Flensburg (or equivalent type approval authority in other countries), which is able to decode all certification marks.

    Original parts on newer vehicles that have been given an "E" mark at the factory may only be replaced with accessories that have likewise undergone E-approval. An E-certified mirror may not, for example, by replaced with a mirror that only has TÜV approval under the German vehicle licensing regulations.

    Universal Turn Signal

    Super-small universal turn signal for any bike. In two different stem lengths (20 mm and 40 mm) and two different lens colours: orange and smoked.


    • Sturdy plastic housing with metal reflector
    • Turn signal dimensions (HxWxD) approx. 28 x 48 x 38 mm.
    • Stem length 20 mm or 40 mm
    • Approx. 20 mm long M10 x 1.25 thread
    • Includes 12 V / 21 W halogen bulb
    • E-approved.
    • Lens colour: orange or smoked!
    • Sold individually

    Because the universal turn signal has been designed to be as small as possible, you will find changing the bulb easier with this little trick: Unscrew the lens, remove the reflector and push the bulb holder together with the bulb with attached cable forwards out of the turn signal (if necessary, use a small pair of long-nose pliers). It is then very easy to change the bulb.

    If your motorcycle did not come with 21 W turn signals, you may have to install a suitable relay.
