things would not work right when the bulbs burn out if you could not run without them but believe it or not my brother in law has a kawasaki that if one of the indicator bulbs burns out you cant start the bike
I think the Suzuki GS750-4 was like that, if the taillight bulb burned out. Or, one of those Suzukis...I remember struggling with that in a shop one day because I didn't know it (nor did the owner): someone had backed into his taillight and broke the STOP filament, but the run lamp still worked, so no one noticed the bulb was bad right away. The bike wouldn't start, and we scratched heads for almost 2 hours trying to discover why the "Electronic Ignition and Control" module would not work unless I jumpered one of the wires to +12 volts. It just cranked the battery dead unless the jumper was there: changing the taillight bulb made the dashboard "LITE" lamp come on with the brake, and suddenly everything was fine.
What twisted SOB engineer could come up with an idea like that? (I can say that, because I AM one!)
