    The right front turn signal bulb on my Flhtk went out. Its a Dual filament bulb.
    So I went to the auto parts store and got a 1157 bulb.
    Put her in. She starts flashing and then goes to flashing Rapid on me.
    I said to myself WTF.
    Was at the harley dealer yesterday.
    Got a Harley 68168-89A bulb. It cost 4.50

    Put it in and it worked perfectly.
    WTF is the deal on the correct bulb from the auto parts ?

    Guess I should of used a 2057. It is a heavier bulb from what I have read.

    for some reason the 1157 you got wasn't being picked up by the
    TSSM.. Probably HD has a special resistor that signals it from your bulbs...
