Replaced bulb for Left Rear Turn Signal, still hyperflashes

Any suggestions as to what to do after replacing a burned out bulb and the turn signal indicator still hyperflashes (2x speed)?

Is there some sort of reset?

Watching YouTube videos on the topic shows that the problem normally goes away when the bulb is replaced.

If it has regular bulbs and it is hyper flashing usually the front or rear bulb is burned out, or the side light could be burned out. There is a separate fuse for the left and right side turn signal/brake lights. They are a brown 7.5 amp fuse per side in the SAM (fusebox) under the dash.If you have installed LED bulbs you have to buy those LED load resistors and connect one at each socket acrossed the positive and negative wires to stop the hyperflashing.
