How to replace right head light of Nissan Sentra when "bright" head light still works?

I’m finding a lot of info online about how to replace a headlamp on a Nissan Sentra, but can’t find anything about what to do if the bright lamps on both sides still works. I assume there are different bulbs for each, but does anyone know how I’d go about replacing the “normal” bulb in this instance. Thanks.
