Question 1

Are these turn signals legal and street-approved?

Accepted Answer

Yes. The Koso GW-02 sequential LED turn signals are fully E-marked and approved for use in Europe. They meet all European road safety standards and are legal for street use on motorcycles. Always check your local regulations, as some regions may have specific rules about sequential lighting patterns.

Question 2

What does sequential lighting mean, and how does it work?

Accepted Answer

Sequential lighting means the LEDs illuminate one after another in a wave-like motion, rather than all at once. This creates a distinctive sweeping effect that's more visually striking than traditional turn signals. The pattern helps draw attention to your intentions on the road, potentially improving safety and giving your motorcycle a modern, custom appearance.

Question 3

Are these turn signals universal and will they fit my motorcycle?

Accepted Answer

Yes, the GW-02 is universally designed with an M8 x 1.25 x 20mm stem, making them compatible with most motorcycles including BMW classics, cafe racers, and custom builds. However, you may need to drill new mounting holes if your bike uses different mounting points. We recommend checking your specific bike's mounting specifications before ordering.

Question 4

What's included in the set, and is installation difficult?

Accepted Answer

Each set includes a pair of turn signals and complete wiring harnesses. Installation is straightforward for those with basic mechanical skills. You'll need to remove your old indicators, drill or use existing mount holes, connect the wiring to your bike's electrical system, and secure the new units. If you're not comfortable with electrical work, we recommend having a qualified mechanic install them.

Question 5

What is the voltage requirement, and are they compatible with my bike's electrical system?

Accepted Answer

The Koso GW-02 operates on 12V DC, which is standard for most motorcycles. They are compatible with any 12V motorcycle electrical system. However, if your bike uses a 6V system (common on older classic motorcycles), these turn signals will not work. Always verify your bike's voltage before purchasing.

Question 6

How durable are the aluminum housings, and do they require maintenance?

Accepted Answer

The matte black aluminum construction is corrosion-resistant and built to withstand outdoor elements. The housings require minimal maintenance—occasional cleaning with a soft cloth and mild soap will keep them looking sharp. Avoid abrasive cleaners that could damage the matte finish. The smoke lens may accumulate dust; gently wipe clean as needed.

Question 7

Do I need special tools or technical knowledge to install these turn signals?

Accepted Answer

Basic mechanical knowledge is helpful but not always necessary. You'll need standard hand tools (wrenches, screwdrivers), a drill (if creating new mount holes), and basic understanding of motorcycle wiring. The included wiring harnesses are designed for simple plug-and-play connections where possible. If you lack electrical experience, professional installation is recommended to ensure proper function and safety.

Question 8

What makes sequential LEDs safer than traditional turn signals?

Accepted Answer

Sequential LEDs create a dynamic, attention-grabbing pattern that draws eyes more effectively than static indicators. This enhanced visibility can help other road users notice your intentions faster. Combined with the E-mark certification ensuring proper brightness and visibility standards, sequential turn signals represent an upgrade in both style and functional safety on the road.
