Is this taillight legal for road use?

Yes, the Koso Sonic LED is E-approved, meaning it meets European road safety standards and is legal for street use on most motorcycles.

Will this fit my classic BMW motorcycle?

Yes, the universal fitment and M8 x 20mm threaded mount make it compatible with most BMW classic models and other vintage motorcycles. The compact 80mm length works well on cafe racers and custom builds.

What does the 2.3W power consumption mean for my motorcycle battery?

The 2.3W consumption is minimal and poses no stress on your motorcycle battery. This efficient LED design ensures your electrical system remains stable even on older or smaller batteries.

Is wiring included with this product?

Yes, the Sonic LED comes complete with a full wiring harness, making installation straightforward even if you have limited electrical experience.

Can I use this as a turn signal on the front of my bike?

This is a rear combo unit. For front turn signals with position light, Koso offers the Sonic LED turn signal (model 942303) which is specifically designed for front use.

What makes LED better than traditional halogen lights?

LED lights are more energy efficient, brighter, have a longer lifespan, and are more durable than halogen. They also produce less heat and give a modern appearance that works perfectly for custom builds.

How do I mount this taillight with the M8 x 20mm threaded stud?

The M8 x 20mm threaded stud screws directly into a female threaded hole or mounting bracket on your motorcycle frame. Simply align the unit and tighten securely. The compact design makes it easy to position in tight spaces.

Does this product work with 6V electrical systems?

No, this unit is designed specifically for 12V systems. Most modern motorcycles use 12V, but vintage bikes may require checking. Using it on a 6V system could cause damage.
