The fast blinker indicator sound is nearly constant when my signal or emergency blinkers are not engaged. When I turn on my blinker to turn or use my emergency flashers the fast sound stops and it is the normal blinking sound.Both front and rear, left and right lights work when the blinkers are on. The emergency flashers work too.This might be relevant...since the previous owner got it in 08, occasionally either the right or left signal would turn on (solid, not blinking) when the brakes were applied. I bought the jeep on October and maybe it did this 30% of the time. It would turn off if just wiggled the flash switch. Anyway, the fast sound does not occur when this happens either. But as soon as it's off, the fast sound will be there.It's a 97 TJ, btwThis just started today. I left the top of during a rain event, we got about .75 inches
