How do I change bulb for brake light on 1997 infinity j30

I don't have the exact info in front of me, but I would think like most vehicles, you need to remove the lamp assembly to access the light bulb sockets and remove them from the housings. There are few and far between vehicles that have bulbs serviceable without removing the assembly. The assembly shouldn't be too hard to remove, but take the time to remove all the fasteners without making any short cuts that could damage the assembly.
