What does it look like? It only monitors a few bulbs, mainly headlights on the front and brakelights on the rear.

Brakelights symbol looks different to the headlight one though.

Not wanting to worry you, but that is what I had starting to happen with my wife's car here, DIS dead However, all this may have been caused by a not great battery!
One of the clues was it would be a little slow to start, then the voltmeter would take an age to come up. Once up to 14V (ish) it was fine.
If she put on heavy electrics before it was at 14V (alternator online) the voltage would drop off. At some low voltage point she had the bulb warning go off.

Of course, it could also be the bulb monitoring unit in the drivers footwell under the dash.
