How do I replace the turn signal/parking light assembly? on 1992 Buick Century

How do I go about replacing the assembly which houses the parking light/turn signal and running light? I cannot even see how to replace the LAMPS let alone the whole assembly!

very easy there is a metal spring that keeps it in place directly behind pull it back and to the side and pull lamp out. the lights just twist off, as far as replacing those... good luck i have no idea.
