Yes, I think it is a separate bulb, but there may be a share ground connection with all the lights.  I would check that out.  I once had problems with one brake light not working at night (worked fine when the other lights were off).  Turned out there was 
a bad ground inside the connector and the parking light and brake light were ground through each other (when the other filament was off of course).  But when they were both supposed to be on (and you had 12 volts on both filaments) no current would flow 
and thus no light.  I changed bulbs a few times (in daylight of course) and viola the problem was fixed, until the next time I drove at night (DOH!).
