Claims

[Scope of utility model registration request]

The reflector includes a glue reflector in the shape of a substantially paraboloid of revolution, a lens that covers the front surface of the reflector, and a columnar filament, and the reflector has a first paraboloid of revolution part whose focal point coincides with the first paraboloid of revolution, and a columnar filament.
and a second paraboloid of revolution tilted downward with respect to the paraboloid of revolution, and the columnar filament is provided to have a length along the horizontal direction and to be located at the focal point of the reflector. A vehicle auxiliary light that is characterized by: .
