Just replaced the bulbs in the back of the car.
All 21W single post lamps. Interesting thing, though. Both bulbs run at 5 Watts per side when the lights are on. Put the brakes on and the outer lamps then run at 21Watts. Most other cars would run a double filament bulb with two circuits to do this. The 9-3 doesn't. And when one bulb fails the other one cleverly takes up the job of the missing one. Rather clever.

I have had a garage phone me up once and say "we've got a 9-3 in for MOT and it's passed apart from the lights are doing something weird can we send it to you for a look?" turned out that yes, quite simply one of the bulbs had failed.
indeed, it uses PWM to reduce the 21w bulb down to 5w brightness.
means that if a bulb fails, it can make another one do that job(s) instead.
Vectras from about MY03 do the same...
...do you think they might be related?
You have to wonder who did the work on that system. Saab engineers or their colleagues at GM...
