that you probably won't have headlight washers fitted
A Xenon lighting system is a lot more effected by dirt and grime than a comparable Halogen headlight. For this reason headlight washers are mandatory on cars equipped with HID (Xenon) light systems in almost every country except the US.
Notice that new Acuras, which are mostly only sold in the US, do not have headlight washers on their cars even though most are equipped with HID headlights. That is, as stated, because the US DOT does not have such a requirement.
Also, most countries like the UK, Germany, Denmark, and other EU countries which often experience high levels of precipitation, and are cold and dark, have headlight washers on almost ALL cars sold their.
