Bulb Failure Modules in an 88 XJ40

I have the common issue of a constant BULB FAILURE LIGHT in my dash, and I want to get rid of it. All of my bulbs are working so I ruled out a bad bulb already. Is there a Module delete that will help it? But first I need to find the exact location of these modules to see if I can repair them or delete them.Where are these modules located?Thanks guys!
I am afraid you will have to check every bulb and make sure that they are seated properly and that all wiring is in tact. Before you reseat each bulb put a little WD-40 on the bulb end and seat. Don't forget to check out back-up light bulbs. Just remember, ant loose connection of bulb or wire will cause the warning. FYI there are some 20 plus bulbs on the exterior of your car
The XJ40 models have a bulb failure unit at all four corners. The are the same left to right but different front to rear. They are roughly 4" x 6".
