A device for driving light sources (L), including:
- a self-oscillating output stage (112) for driving at least one light source (L),
- a starter circuit (120) for starting the self-oscillation of the output stage (112), and
- a control circuit (108) adapted to drive (S) the starter circuit (120), for selectively starting the self-oscillation of the output stage (112). The starter circuit (120) comprises:
- an RC network (R s , C s ) with a capacitor (C s ) being chargeable from a voltage (12 V), and
- an electronic switch (T 1 ), driven (S) by the control circuit (108) for selectively connecting the capacitor (C s ) of the RC network (R s , C s ) to the output stage (112) for selectively starting the self-oscillation of the output stage (112).
