01 · SIGNAL HEAD
Three-aspect LED head
Three aspects at standard 200 mm pitch behind a single-piece smoked polycarbonate face. Per-aspect current monitoring detects single-LED degradation before it becomes a visible fault. Visor-less design subject to phantom-signal validation under EN 12368.
| Aspect pitch | 200 mm |
| Face | Smoked polycarbonate |
| Visors | None (subject to test) |
