An aircraft glazing unit 9 has a body 10 of transparent material and at least one subsurface thickness indicator 13-17 at predetermined depths within the material. The indicators may be provided in groups 13-16, and may be provided at different depths within the material; at least one of the indicators having a mark identifying a minimum allowable thickness 16. Preferably, the indicators are laser etched into the material. The glazing unit may form part of an exterior aircraft light, which is susceptible to erosion during use; during maintenance, the condition of the thickness indicators may be visually inspected by ground crew after polishing of the exterior surface to remove erosion.
