my 940 has a 3rd brakelight and i have installed an additional brakelight in the spoiler. I hooked it up to one of the existing brakelights and now every time i brake the yellow bulb failure light comes on. in other words: the error light is sensitive to how many and what kind of bukbs you install.

i have the same setup: third brake light + a honda prelude spoiler with a diode brake light.
I sometimes get these "bulb out" warnings for a few pushes of the brake pedal once in a while.

The bulb-failure warning device works on the resistance in the circuit, lighting the warning bulb when the preset resistance is not met or exceeded.
You could try using a small relay to switch the extra brake light bulb, taking power from a separate fused circuit.

Kinda trivial, but my 91 940 and my 91 740 both had that style IC. Might wanna change the title?
