A sensor system comprises a LiDAR unit, a camera for visible light and a cover through which light arrives at the LiDAR unit and the camera. The cover comprises a layer containing dyes. The light transmission of the cover in the range from 380 nm to 780 nm is 3% to 25% and in the range from 380 nm to 1100 nm is 40% or more. The attenuation of the LiDAR signal by the cover is such that at least 65% of the original signal intensity reaches the LiDAR detector. The layer containing dyes contains a composition comprising i) at least 70% by weight of a transparent thermoplastic polymer, ii) at least one green and/or red dye and iii) at least one red and/or violet dye. The product of the sum of the weight % fractions of dyes ii) and iii) and the thickness of the layer containing dyes is 0.041 to 0.12 wt % mm. Finally, the composition contains 0% to 0.0005% by weight of IR absorbers.
