I checked my order history and the bulbs I ordered are no longer available. So, these are obviously the wrong socket type but the same idea.
Now on these which are the correct style one side is running light the other is the turn signal. If you take a peek into the tail secion of your STeed1300 you will see that the turn signal socket has only 2 wires, ground and power. The brake has 3 wires, power, ground running light. IIRC, could have these backwards. Anyway, the bulb sockets are the same for both the turn signal and the brake bulbs with one of these having an open spot for a 3rd wire. You can add a jumper wire between this empty spot and the running light power on the brake by stripping the end of a short wire, removing the bulb from the socket inserting the end of the wire and re-installing the bulb. I went one better and installed an OEM plug from an extra full harness that I had laying around.
