Abstract

Techniques related to retroreflective surface layers for micro-mobility transit vehicles are disclosed. A retroreflective surface layer may be formed over at least a portion of a component of a micro-mobility transit vehicle by forming a powder coat layer over the portion of the component and baking the powder coat layer to cure the powder coat layer. An uncured clear coat layer may be formed over the powder coat layer. The uncured clear coat layer may be impregnated with a plurality of glass beads via an air-pressure applicator. The uncured clear coat layer impregnated with the glass beads may be baked to cure the clear coat layer. The retroreflective surface layer may include the powder coat layer, clear coat layer, and the plurality of glass beads distributed within the clear coat layer. The retroreflective surface layer may reflect incident light back to its source with minimal scattering of the light.
