If that's a light lilac coloured hose ( faded ) then that's the headlight level adjuster vacuum hose. Under the headlights there is a little diaphragm controlled leveller. It's automagic so you may not have a control knob for it. If your car really does not have a levelling system you will find the hoses blanked off at the headlight. ( No point in having different engine hoses for car with/without so as with a lot of wiring harnesses there's 'optional' stuff that just ends nowhere )
