1. An electronic load for installation in a power supply of a vehicle lamp, the electronic load comprising:
a first connection node connected to two first connection sections adapted to be connected between respective corresponding connection sections of a first line carrying a voltage potential;
a second connection node connected to two second connection sections adapted to be connected between respective corresponding connection sections of a second line carrying a reference potential, wherein a difference between the voltage potential and the reference potential comprises a supply voltage configured to be supplied to the vehicle lamp; and
a current sink circuit coupled between the first and second connection nodes, the current sink circuit configured to cause a substantially constant current flow independently of a time-varying supply voltage from at least one of the first connection sections to at least one of the second connection sections,
wherein the electronic load is connectable to the first and second lines in parallel with the vehicle lamp.
