I use a Kisan SignalMinder and a loud buzzer (Radio Shack) I have mounted under my tank. My system cancels the signal light after a period of time and it also has a loud signal while the lights are flashing. When the lights are canceled the tone on my buzzer changes pitch reminding me to cancel the signal switch by pushing it inwards once. If I'm a long time at a light the signal cancels and I can hear the pitch change which reminds me to activate the signals again.
I like the system I have and would have a hard time rmembering without it. I followed a bike today for miles with his signal flashing and was grateful that doesn't happen to me.
