Illuminate.

The foundation of the RADROAD-APEX platform. Internally illuminated signs with uniform luminance, fail-safe retroreflective backup, and infrastructure-grade durability.

RADROAD-APEX technology is patent pending.

At a Glance

APEX I delivers even, internally illuminated legends across the entire sign face — visible at 1,000+ ft, dark-sky friendly, and fully MUTCD compliant. When unpowered, the retroreflective face still functions as a standard sign.

Uniform Illumination

Even luminance across the entire sign face — no hot spots, no dim corners. 2:1 to 4:1 ratio, well within AASHTO guidelines.

Fail-Safe Visibility

ASTM D4956 retroreflective sheeting on every sign face. Power loss never means visibility loss.

Infrastructure-Grade Build

Aluminum chassis, polycarbonate face, IP67, −40°F to +135°F, 150 mph wind-rated.
