headlamp exhaust?

[icon]

Just curious, napansin ko lang sa headlamp and sa foglamp assembly ko na there is a rubber tube that sticks out. Parang exhaust ba to para marelease yung heat buildup sa loob?
I'll try to get pics.

you are correct sir its purpose is for the heat to escape

It's also there to prevent fogging up the lens.

Serves also as a drain if its located below.

and since we're in a heavily polluted country, it is where particulate matter seeps through. that causes the blackening of reflectors and lenses.
