Abstract
A lighting apparatus for vehicles with a light source unit and optical equipment for generating a specified signal light distribution to provide a specified signal function. The optical equipment consists of at least two optical units. A first optical unit deflects a first light beam emitted by the first light source is designed to generate the specified signal light distribution. A second optical unit, a hologram element, is used to deflect a second light beam generated by the second light source to create a holographic light image so that the specified signal function consists of the signal light distribution and the holographic light image that is spaced at a distance.
