A riddle

[januszt]

While fighting with my car starting issue, i have found a piece of rubber fitting(?). It was laying between radiator and front bumper. Does anyone know what is it -> where should I put it back.
Few photos and some details attached.
Details:
Identification (?): "151296" & "18" on both sides of the bigger end. Internet checked, nothing found using these numbers
Size:
Length: 50mm (longer part) 16 mm (shorter).
O Diameter: 7mm (smaller) 14mm bigger.

Any ideas?

I think those kind of rubber boots are typically used as drains/vents from the rear of the headlamp units.

You are right! Found it on random headlamp photo: http://img18.allegroimg.pl/photos/oryginal/55/76/45/05/5576450551_1

To be honest, not looking for this particular part, I would not even notice it being there.

Thanks! I will be checking tomorrow which headlamp it is from, to put it back.
