We don't have much more detail on this one beyond the part number and the positive-ground call-out. If you're not sure whether your bike is positive or negative ground, check before ordering, since running the wrong polarity bulb in an LED can mean it simply won't light up.
Call the shop if you want us to confirm which sockets or fixtures on your bike take a 989-base bulb before you order.
