400E vent light
 

The left vent light is out whereas all of the other lights [fiber optics I think] work. How do I get at the connection or bulb? Rather than breaking plastic to get at it, is there a tool to get at the rotary wheel and check? In same vein is the shifter light a bulb or more optics. It's a 92 400E.

Do a search. You will find clear directions on how to relamp the bulb. Also be sure that you replace with a bulb of the same wattage.
