The driver arrangements (1) further comprise driver circuits (200) for driving the light sources (301-308) via the division circuits (100). The driver circuits (200) have driver outputs (201-202) for supplying the input signals to the division inputs (101-102). Such driver arrangements (1) no longer require a switch per light source (301-308).

The driver circuits (200) comprise controllable couplers (221-222) or controllable sources (211-212).
