Tunnel Active Road Stud (Guidance Marker)
The tunnel active road stud (also called a guidance marker or raised pavement marker) is a traffic safety device for tunnels and highways, featuring an LED light source and dual-sided emission design. As an active road stud, its self-illuminating capability overcomes the limitations of traditional reflective studs, clearly outlining road contours in low-light, fog, or rain. It assists vehicle positioning and guidance, significantly enhancing nighttime driving safety.
