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.

The aqueous ink includes a pigment, a resin dispersant and an aqueous medium. The pigment contains C.I. Pigment Orange 43. The aqueous ink has an absorbance ratio of 0.95 or more to 1.15 or less, which is represented by the following equation (1). An absorbance of 50% by mass of an upper layer when the aqueous ink is centrifuged at 217,000 G for 30 minutes at a pigment content of 1.5% by mass is less than 0.20 in a wavelength range of 350 nm or more to 550 nm or less.
