 CANBUS wiring: How does it work? - Dave_
It does allow for some clever tricks, though.

The Vectra C has two tail light bulbs in each rear cluster. All the bulbs are 21w single filament items. With all bulbs in working order, the electronics will pass a small current through all four when the sidelights are switched on, giving the impression of conventional 5w bulbs. When the brakes are used, the electronics increase the current to the upper pair of bulbs, giving the impression of conventional twin filament 21w/5w bulbs. If either upper bulb should blow, the electronics will then divert the brake light signal to the lower bulb, giving two full brightness brake lights even with one blown bulb. Clever.
