Electronic Steerable Beam Signal Head
ESB
Limited Range of Visibility Applications
OVERVIEW
The Electronically Steerable Beam (ESB) traffic signal
features an electronically programmable signal head with
an array of LEDs as the illumination source. The LEDs can
be programmed to electronically steer the light beam for
applications requiring limited zones of vertical and/or
horizontal visibility. Both vertical and horizontal viewing
angles can be programmed for typical turn pockets plus
restrict viewing for far side indications. Contact Intelight
today to see how our ESB signal can help you improve
safety at intersections with close spacing or unique
geometry while saving hours of staff time and
dramatically reducing exposure to traffic dangers during
installation and maintenance.
HIGHLIGHTS
• Configure/Adjust Indication Viewing Window from
Ground
• Program wirelessly from a windows laptop via Intelight’s
NEW wireless Router (no need to place signal in flash)
• Does not require louvers or other external blocking
devices
• Thermally enhanced modular housing – improves life
• Ambient light adjustment – signal light intensity varies
automatically with changes in ambient light
• Reduce energy and maintenance costs
• Meets or exceeds traditional traffic signal specifications
• Power consumption averages 8 watts
• Standard three year warranty
APPLICATIONS
• Off Angle Geometry
• Close Proximity Signalized Intersections
• Intersections where viewable field of the indicator
should be steered to exclude or include drivers to
insure safety.
