Many older bikes don't have hazardlights. For this circuit I used the onboard turn signal relay to generate
the alternating signal
for the hazardlights. Via a multipole relay the turning lights are disconnected from this relay and
reconnected all four together in
hazard-mode. At the same time the turning light relay is feeding these four turning lamps for
In hazard-mode the circuit is being fed directly from the battery so you can leave your bike locked
behind while using the hazard-mode. This can be very useful if you have to leave your bike at an 'invisible'
