Welcome to the forum!

I can't help you much with the bike rack. Do you want an internal (in the cargo area, rear seat folded flat) or the external hitch mounted rack?

Depending on what kind of headlights you have (xenon or halogen), there may be little function for the inner lights. They function as the flash to pass high beams, and as the DRL for North American vehicles. For vehicles with bi-xenons, the outer headlamps work as both the dipped and full (high) beams. For halogen vehicles, the inner headlamps are the full beams.
