Outer Tail Light Bulb !!
How to change tail light bulbs on 89 and earlier.
This is the best way I have found at changing the tail light bulbs on the older C4's with the round tail lights, 89 and earlier. Follow the order I have it written and you shouldn't have any problems as long as you can reach your arm in through the license plate opening.
What you do is reach in through the license plate opening after you have pulled the license plate. Remove the bulb socket on the inner tail lights.
Remove the two screws holding the inner tail lights lense. Remove the inner tail lights lense. Reach in through the inner tail light lense hole and change the outer tail light bulbs.
Go ahead and put in the new bulbs for the inner tail light sockets. Put the inner tail light lense back in with the two screws with arm reaching in through the license plate opening. Then screw in the inner tail light bulb socket. And replace license plate.
I recommend you put in long life bulbs. I also recommend if you don't already have one. Go to Autozone and get a 10mm ratchet wrench. The one I have lets you fold the ratcheting end up to 90 degrees. Makes this job alot easier vs. using a socket wrench. Though, you could get by with a 10mm socket wrench.
