Turn signal volume
 

This is going to sound nuts, but I need to make them louder.
My left hand blocks the left blinker from view and I quite frequently don't hear them over the stereo/road noise, so I've turned into that old man who drives for miles with his left blinker on.
Any constructive suggestions?

wire a small speaker to the outputs, like one from frys. probably would be super annoying.

I believe the clicker for the turn signal is in the gauge cluster itself. You would have to wire an external speaker or buzzer, like mentioned above. OR tap into the wires going to to turn signals and have bigger turn signal indicators wired up on the inside of the car. Old man status

The click is the sound of the flasher module working. I found my tapturn module to be a bit louder than stock, but not a whole lot more. The guy that makes the tapturn could make you a louder one if you ask...
