The problem......
You've fitted LED indicator bulbs and a 2 pin flasher unit to your motorcycle. Everything worked fine with the original bulbs but now when you put the indicators on they all flash like hazard warning lights. This is because the new LED bulbs require so little current that the tell-tale bulb passes enough to flash all indicators at once.
The answer....... our simple to fit LED fix kit.
Comes with a connection diagram. A simple alteration to the wiring at the tell-tale and your indicators will work as they should.
Works on 6 and 12v
