This unit has the benefit of having the 90dB audio sound along with the Ultra Bright L.E.D.
The buzzer and the Ultra Brigh L.E.D. sounds/flashes in time with indicators as soon they are turned on.
This acts as an extra audibble and visable warning that indicators are on.
The L.E.D. can be seen in direct sun light.
This comes with everything that is required to fit (excluding tools).
Very simple installation.
Connect 1 red wire to left indicator, connect other red wire to right indicator,
connect black to any earth point on bike.
The viewing angle of the L.E.D. is quite large so the position can be adjusted to enusre that you notice it while riding.
