Assuming aliens exist and have been visiting Earth, why wouldn't they?

If they have the technology for interplanetary travel, why do they need headlights?

And assuming their craft travels in excess of the speed of light, their headlights would be useless anyway...........

What does interplanetary travel have to do with lights once they are in our atmosphere? I don't need lights when I'm driving across the salt flats in the middle of the day well above the ton, but once it gets dark and I'm driving on congested roads I turn on my lights.
