Mine does the same. I've been advised to get matching bulbs all around.

I replaced the 1034 bulb with an 1157, which I thought was compatible and even long lasting.  To my surprise, it worked, but with a difference.  It blinked rapidly, as if a turn signal light was out, although the front  was blinking, as was the rear.  Drivers side blinks at rhe correct rate.  Am I looking at an anomaly between the 1034 vs.1157, or a bad ground?  Or something else?
