Why does my turn signal on my jeep wrangle have a fast flash?

Answer 1

A fast flashing turn signal, on most any vehicle, is an indicator that a turn signal bulb is going out or has gone out on that side(i.e. front turn signal on passenger side flashing fast, check the rear turn signal bulb on passenger side.) This will cause the light on your dash board to flash fast as well. This is generaly a good time to replace all of the bulbs, turn signal, running lights, and break lights, as they are so cheap. Also check deck light or top break light if applicable for burn outs.
