Can anyone help in improving the indicator sound in my Suzuki Swift. Could be my hearing I suppose but the indicators at times are left running whilst driving which can be dangerous.
Adding additional buzzers, relays etc alters the circuit impedance and the flasher speed increases considerably. I have been advised to connect opto-couplers to each side circuit, using 4N25's but I need advice regarding how to couple these components...even the basic connection circuit (on-line) does not show the connection points...can anyone help.
