96 850 Turbo: My instrument cluster bulb-out indicator is lighting

The bulb sensor is probably failing.

Your suggestion sounds reasonable, but looking at IPD and *** for brake light bulbs, it looks like they sell the 1156 bulb, which is the same bulb I bought at Autozone. To test it out, I went to my local Volvo dealership and bought a couple of bulbs. Rather, I ordered them since they don't keep much stuff for 850s in stock. I asked if they were just 1156 bulbs, and the service guy said 'Ours are VOLVO bulbs'. That is, I don't really know what I am getting, but I'm going to be pretty disappointed if they are just 1156 bulbs since the dealer charged me $13 apiece for them. Hard to believe.

If they aren't 1156 bulbs, I'll measure the resistance and compare it to the 1156 bulbs I got earlier.

Be sure you use the proper bulbs. Although bulbs look the same, they have different amounts of resistance and that's what sets it off.

Anybody know what this could be? The bulb-out indicator (orange, down on the left bottom side of the instrument cluster) lights every time I press the brake pedal, and goes out when I release the pedal. I've tried changing the brake light bulbs and cleaning the sockets -- all of the exterior lights come on and go off just as they should, but the indicator keeps telling me there's a problem.
