IN-VEHICLE LIGHT APPARATUS

A light apparatus mounted on a vehicle includes a lamp that emits light into a first region through a first cover and a radar provided on a lower side or an upper side of the lamp. The radar includes a separator provided between the lamp and the radar, a circuit board having a board surface arranged in a substantially horizontal manner, and an antenna that is disposed on the board surface of the circuit board, transmits electromagnetic waves through a second cover in a second region that is at least partially different from the first region, and receives reflected waves through the second cover from objects outside the vehicle in the second region.
