A vehicle lamp includes a lamp housing with a red lens forming a lamp chamber, an excitation-light irradiation unit for emitting excitation light with a wavelength shorter than 500 nm, and a light conversion unit disposed in the lamp chamber. The lamp lens is a red lens. The light conversion unit includes a light emitting film that receives the excitation light and emits secondary light of a wavelength longer than 500 nm, a reflection film for redirecting the secondary light towards the light emitting film. The secondary light exits the vehicle lamp through the red lens.
