Turn Signal

This is a small annoyance...
The "tick tock" sound of my turn signals and four way flashers is barely audible at idle, much less when I am driving. I have had the embarressing experience of driving for miles with the turn signal on before I noticed the dashboard flasher (doesn't say much for my peripheral vision). Is this another 911 quirk like our dim dashboard lights? Just wonderng if it is worth buying a new turnsignal relay.
