Two. One of them is red half the time, but since I'm coasting down a hill towards it for about 1/3 mile before I get to it, I just slow down if the timing is wrong, so that it's green when I get to it. The other one is only red about 1/10 the time, I'm on the major road and a small road T's in to it, the light's on a sensor so it's mostly green in my direction.

The former doesn't seem to be on a sensor, so it's not an issue. The latter has a sensor on the minor road. Occasionally I've been coming down that road going back towards work, hitting the light in the left turn lane. It does pick up my bike and change after 20 seconds or so.
