These small and powerful bar end indicators by Motogadget are the ones to go for. The finish is superb and they are also easy to mount. Simple and elegant are the words we go for.

Its tiny dimensions and minimal design make it almost disappear on the vehicle. Due to the IntensiLED® Technology, the emitted light is extremely bright when switched ON and definitely can no longer be overseen. 
Additionally, greatest visibility and safety will be ensured by the patented TranzLight® Technology (TLT) with a wide beam angle.

Price is per piece.
Always make sure to order a complete set consisting of the left and right side turn signal assembly!
