a housing;
an outer cover covering an opening of the housing; and
a lighting unit disposed in a space formed by the housing and the outer cover,
wherein
the member is at least one of the outer cover and the housing, and
a thickness D of at least one of the outer cover and the housing is defined by a following equation

D=¼×λ/εr1/2×(2n+1)

here, λ is a wavelength of a radar radio wave, εr is relative permittivity of at least one of the outer cover and the housing, and n is an integer of zero or more.
