DRLs are obligatory here,
so was more than happy when i found the option in my computer thingamajigy controlled by one of the many thumb wheels on the steering wheel,
mine light up the inner HiDs at low power and stick some small sidelight things on, on the front, no idea if the back even lights up i must check, as its only the fronts that must be lit to comply with Polish traffic law (maybe european too, as i said i must check

)
having now spent a while driving here i can say for sure that they are a good thing i think everybody should do it.
