  • Patent number: 5013181
    Abstract: A night-visible traffic lane marking device for aircraft landing and takeoff strips, roadways and the like. The markers are installed embedded into the lane with their upper surfaces flush with the traffic surface. Reflective, fluorescent or phosphorescent elements are provided encased within a transparent uppermost layer. Each element extends vertically to provide a substantial profile for long distance visibility. The transparent covering extends a substantial distance from the reflective element in the direction of oncoming traffic, to increase long distance visibility. Night visibility of the element may be further enhanced by a self-contained, solar powered, illumination unit installed within the transparent layer.
