parking light?

What is the parking light? Is it the bulb in the orange part of the corner lamp or the clear part? Is the bulb in the orange part even supposed to light at all? On my car the bulbs in the orange part on both sides dont do anything and i would like to know what they are for if I need it to pass safety inspection.

Thanks

the parking lights are the lights that go one when you turn the switch once, they dont blink.
