Turn signal blinking too fast. How can I tell if it is front or rear bulb? Ford escort?

I have a 2000 ford escort zx2. My right turn signal is flashing too fast. How do I tell what is causing problem? Could it be front or rear bulb? Not very knowledgable about cars thanks in advance.

My God… How do you tell which bulb is bad? You get out of the car and look to see which one is not working!

You hit the indicator switch then get out your car and look to see which on it is

Set your indicators to turn, look around the car and check if all the indicators on the side you are indicating light up.
If not then check the bulb and replace.
If all the bulbs are lit then its the relay that gone.
Its a small square box that simply pulls out ( a bit like a fuse ) , simply buy a new relay and replace it.

Simple. The faulty bulb fails to flash. This means too much current in circuit causing remaining bulb to operate twice as fast.

Turn them on and look. The bad one won't be flashing and the good one will be.
