With the development of automotive rear light technology, people have a higher pursuit of the personalized and three-dimensional image display function of automotive rear lights. In response to this situation, based on the principle of holographic technology, this paper proposes two holographic car taillight schemes, transmission type and reflection type, three-dimensional modeling of automotive rear lights, and production of automotive rear lights and optical components to realize the three-dimensional image display of automotive rear lights. The three-dimensional display effect and display performance parameters of holographic automotive rear lights were tested and analyzed. Among them, the diffraction efficiency of the transmissive holographic automotive rear light can reach 28.75%, and the light average transmittance is higher than 86.83%, which has a good three-dimensional display effect. Reflective holographic car taillights can also present clearer three-dimensional images under white light.
