figured out that if you depress both left and right turn
signal switches simultaneously, all four directional
signal lights will flash, just as if you had turned on the
flashers using the rocker switch on the panel.
This
is a great way to call attention to yourself or to notify
motorists behind you that you are slowing for a traffic
jam ahead - as the European's are known to do!
