There's no blinker bulb, sorry to say! Blinker is a LED element. If the blinker is dead, you need to replace the whole lamp housing. Although this is a very uncommon item to fail as the LEDs should outlast the car. Sure it is not anything else wrong?I have ordered the owners manual but I would really like to replace a blinker bulb asap.
There are screws holding the whole element in place from behind. You need to work your way through the battery compartment opening. There are four nuts holding the lamp in place, you can reach them through the battery opening.I don't see how one removes the housing
