Hi Nate,
nah, signals only.
Front signals on an XS1100 Standard have twin filament running/signal lights and will bolt right on so all you need to do is run another blue wire but the bastards are square instead of round.
You can modify your existing signals by swapping their single filament bulb holders for twin filament bulb holders. If you can't find just the bulb holders you can buy two el-cheapo trailer lights and rob the holders out of them.
Note:- The bulbs in trailer lights are usually 22W/6W and you'll need 27W/6W to work the stock flasher.
