A device for signal light display and environment detection includes a first light source for emitting visible light in a first spectral range in a temporally modulated manner, and a light source for emitting invisible light in a second spectral range. A lighting surface is designed to reflect and/or transmit light in the first spectral range in a diffused manner. A material layer is transparent for light in the second spectral range, or reflects this light with almost no diffusion. A deflection unit in the device deflects the light from the first light source onto the lighting surface and the light from the second light source onto the material layer. The material layer is located in relation to the deflection unit such that invisible light deflected onto the material layer is emitted for environment detection in an environment of the device.
