Yes, the Koso Shadow LED turn signals feature E-mark certification, meaning they meet European safety standards and are approved for road use. Always verify local regulations in your country to ensure compliance.
Universal fitment means these turn signals are designed to work with most motorcycles through the standard M8 x 14mm threaded mounting. However, fitment depends on your specific bike's design. Measure your existing turn signal mounting location or consult your motorcycle's manual to confirm compatibility before purchasing.
LED turn signals are significantly brighter and more responsive than traditional halogen bulbs. The dual 12V / 2.6W LEDs in the Koso Shadow provide sharp, concentrated light output with faster activation, improving visibility and safety on the road. They also consume less power and generate less heat.
Installation is straightforward for most riders. The complete wiring harness is included, and the M8 x 14mm threaded mount is a standard design. If you're comfortable with basic motorcycle maintenance and have basic tools, you can typically install these yourself. However, if you're unsure about electrical work, professional installation is recommended.
These turn signals are sold individually. To complete a full turn signal setup (front and rear on both sides), you will typically need to purchase multiple units. Most motorcycles require four turn signals total—two in front and two in the rear.
LED turn signals have a significantly longer lifespan than halogen bulbs, typically lasting 25,000 to 50,000+ hours. In practical terms, this means you'll rarely need to replace them during the life of your motorcycle. Halogen bulbs, by contrast, typically last 1,000 to 5,000 hours.
Absolutely. The matte black finish and compact design of the Koso Shadow make them an excellent choice for cafe racers, classic motorcycles, and modern customs. Their minimalist aesthetic complements retro-inspired builds while their advanced LED technology provides modern safety and performance.
The 35mm arm length refers to the distance the turn signal extends from the mounting point. This measurement is important for clearance—it determines how far the signal protrudes from your bike's body. A longer arm may provide better visibility but could interfere with bodywork or fairings. Measure your existing turn signal or intended mounting location to ensure proper fit.
