Here's a good old story about a bulb ............. Double filament, offset pin, (side and brake light, can't remember the Lucas number) .... The side light filament failed and dropped onto the live "post" of the brake light filament. Turning the side lights on put a live feed back to the brake light switch and the engine management, no power no rev' ... Took a bit of finding especially when the lights were turned off, everything returned to normal
