The Service manual states that the bulb should be removed from the instrument cluster once it goes off, it never mentiones anything about reseting the light, but reseting it is even better then tossing the bulb, Great work!

I've replaced the sensor and hooked the bulb back up previously and since that time the O2 light has been coming on and off whenever it felt like it, but I'll take a look into resetting it.
