why is my blinkers blinking so fast after i put a new led blub in it.
LED bulbs have much less resistance than conventional incandescent bulbs, thus the flasher thinks there in no bulb in the socket or it is burned out. You will need to obtain some load resistors to make the flasher flash normally. Do some googling or contact the manufacturer of your bulbs.
