On mine the DRLs and front sidelights share the housing (and maybe the bulb).
With ignition on, lights off: just the DRL/sides are on bright.
With lights set to side: the DRL/sides are on dim and the tail-lights are also on.
With lights set to head: with ignition on you get everything, but with ignition off you get nothing - not even side lights.
So if you've been testing by turning the switch past the side, to the head position, but with ignition off, then what you see is correct.
