1990 Volvo Wagon brake lights

The brake lights on this wagon come with lower housing 1157 bulbs for tail and brake lights, and the upper housing 1156 bulbs for brakes only, The upper 1156 is the problem not working, the 1156 bulbs are not blown and do not come on when brake is applied, however, the lower 1157 bulbs for tail and brake lights are Ok and properly working, the bulb failure light came on in instrument panel, the 15-A fuse is Ok, when brakes are applied, only the bottom brake lights work only, both upper 1156 bulbs are good, Help! Also when I checked the brakes fuse the 15-A and it was good, I noticed there is 3 "box type fuses alligned adjacent to the 15-A fuse, is one of them related to the brakes also? If not, got me puzzled, thinking about splicing into my lower brake light's wires to make it work, just a temp solution, any suggestions will be very much appreciated thank you, Jerry of West Virginia, USA "What an idiot I feel now, forget about my question, read owner's manual, found out that they are rear brake "FOG LIGHTS" and control switch is on dash under instrument panel, But why does that stupid instrument panel "bulb failure warning light keeps coming on when I turn on my head lamps and tail lights? There are no blown bulbs and are all working properly with exception with the bulb under the hood for night time engine view! Surely this is not of an important major issue, after all good ole flash lights work better to see what your doing.
