Left Blinker

hey wussup i was driving this morning and i went to turn left and i put my blinker on and for some odd reason it was clickin like really really fast like strobe light style then i got home and etsted it out it blinks crazily the right blinker is working fine, i changed my tail light bulbs earlier in the morning and the bliner was fine until i changed it do you think this is caused by changing the bulbs anything would help so i dont get pulled over for some stupid reason for having like a strobe blinker lol.... thanks

Are all of the bulbs associated with the left signal blinking when they should? If you put one in that's not making proper contact, it would cause the signal to blink rapidly to alert you to a bad bulb. Also, you changed the bulbs in the tail--have you checked to see if the front signal is out?
