NB3A SERIES

Single Light – 3 Color Signal Tower Light

One Light. Three Colors. Smarter Signalling.

The Nile Bharat NB3A Series is a compact industrial signal light designed to provide three essential machine-status colors—Red, Yellow and Green—from a single light unit.

Instead of using multiple stacked light modules, the NB3A combines three-color signalling into one compact Ø50 mm indicator, providing a clean, modern and space-saving solution for industrial machines and automation systems.

Whether you need to indicate machine running, warning or fault conditions, the NB3A provides operators with simple and instantly recognizable visual communication.

1 LIGHT. 3 COLORS.

🔴 RED – STOP / FAULT

Provides a highly visible indication for machine faults, stop conditions, alarms or situations requiring immediate attention.

🟡 YELLOW – WARNING / ATTENTION

Ideal for communicating warnings, standby conditions or situations requiring operator attention.

🟢 GREEN – RUN / NORMAL

Provides a clear indication of normal operation, machine running, ready status or successful process conditions.

Three Machine States. One Compact Signal Light.

The NB3A eliminates the need for a traditional three-layer signal tower when only the primary Red–Yellow–Green machine conditions are required.

Compact Design. Maximum Visibility.

Ø50 mm Industrial Signal Light

The NB3A combines a compact Ø50 mm body with a large illuminated surface to provide effective visual signalling without occupying unnecessary machine space.

Its single-light construction creates a cleaner, simpler and more modern appearance on machines, control panels and automated equipment.
