Most turn signals in our range are E-approved (ECE certified) and therefore legal for road use in Europe. Check the product specifications for the exact certification.
Our turn signals are universally applicable to most motorcycles. Check the thread size (usually M8 or M10) and electrical specifications (12V). If in doubt, contact us with your motorcycle model and we'll help you.
Yes, when switching from incandescent to LED turn signals, you usually need an LED-compatible flasher relay. Without it, the LED lights will flash too fast (hyperflash). You can also use a load equalizer as an alternative.
Sequential (running) turn signals illuminate the LEDs one by one in the direction of the turn, giving a dynamic and modern effect. Normal turn signals flash all LEDs simultaneously. Both types are ECE-approved.
Most turn signals have a standard thread mount (M8 or M10). Connect the wiring according to the color scheme: usually yellow/orange for the turn signal and black for ground. For 3-in-1 combo lights, add red (taillight) and an extra wire for the brake light.
