The Barracuda X-Led B-Lux indicators have an E-mark and are therefore permitted in Europe. All variants are made with an aluminum housing and are available in various colors. This generation of indicators are equipped with the high-quality and bright LEDs and have a special optical lens that increases the beam angle and therefore visibility. These flashing lights have a consumption of 1 Watt. To cancel out the difference in resistance (and thus prevent faster flashing), 10W or 21W resistors can be built in between.
Each motorcycle has its own specific system and therefore LED indicators often require resistors to prevent faster flashing after mounting.
This is true for 99% of the motorcycles available, but there are also some cases where a specialist should look into it to fix this for you.
