The left hand turning signal has started flashing very rapidly on the front and rear. Is this a bulb problem?Or is it a expensive electrical problen?I have been told it may be the bulb thats ready to burn out. This just started happening the other day. Can I fix this myself?

Newer cars use electronic flashers that flash faster when there's a break in the circuit. That is most commonly caused by a bulb that is burned out but it can also be caused by a break in a wire or a corroded contact in a socket. Start by checking for which bulb isn't working. When they all seem to be okay, compare the left and right sides to see if there should be two bulbs lit up.

Turn signal indicators or blinkers as they are called work in a specific manner which is dictated by the turn signal bulb and circuit resistance.
