yeah I know you did not ask!
There is a unit on vehicles called a flasher; it controls the flashing of the turn signals and emergency lights. It also is responsible for the clicking sound that you hear when they are engaged. I became familiar with this device when I drove an ice cream truck a couple summers in Oklahoma City while I was in college. Since we drove very slowly in neighborhoods and had kids running up to the truck we had the emergency flashers on much of the time. This resulted in the flasher unit having to be replaced several times a season.
I don’t have this problem in my Tacoma, but in my MX-5 Miata and my wife’s Subaru Outback I have an issue with leaving the turn signal on. In the Outback if I get everything adjusted just right, I can see the indicator on the dashboard. I have a harder time in the Miata. This results in the old man syndrome of driving with my turn signal on for miles and miles and miles.
I went looking on the Internet, and they do make flashers with a louder sound. One was advertising up to 5 times louder than normal. Why they are not marketing these aggressively to senior citizens I do not know, but if anyone wants to buy me a birthday present next year…
Just as an aside I was driving somewhere with the grandkids and their mother in the Outback. She advised me that I still had my turn signal on even though I was done changing lanes. I politely informed her that I was entitled as I was over 60.
And so it goes.
