I think the flasher is electronic not mechanical which is why it's so quiet.

 

there is not technically a "flasher". its completely solid state.
the noise you hear is actually manufactured by a small speaker, as the system should be completely noiseless.

the higher line endeavors and galants actually had an option to make a faint "beep" if you so desired, but the outlander does not.

And just in case people didnt realize, these cars have "euro" style turn signals. Meaning that if you "bump" the turn signal stalk WITHOUT fully engaging it, the lights will flash 3 times (useful for lane changes).

 

I set mine to blink 3 times when you tap the signal down....I like how low the signal volume is. My friend's new BMW had the loudest turn signals...I can hear them over the radio sometimes.
