City of Los Angeles Purchases Additional USA Signal Technology Energy Saving LED Powered "Redundant" No-Right-Turn Signals

DALLAS, TX--(Marketwire - August 14, 2007) - USA Signal Technology, Inc. (PINKSHEETS: USST) ( has received additional orders from the City of Los Angeles for its proprietary LED (Light Emitting Diode) Lane Control Signals (LCS) configured as "No Right/Left Turn Signals with International Symbols." The LED signals ordered require only 10 percent of the power of conventional signals and follow a purchase order from Texas Department of Transportation (TXDOT) for similar innovative Wireless LED Lane Control Signals for use in highways (LCS).

The No Right/Left Turn Signals are placed in intersections where, at certain specific times or under certain conditions, the traffic must be diverted or redirected, such as in flooding conditions, during special events, commuter lanes, or evacuations. The Lane Control Signals, which are now growing in use, provide critical traffic control and distribution functions, especially during rush hours, in the event of an evacuation, or other natural or man-made disasters. They show a specific lane's traffic condition: a green arrow for a lane flowing freely, a yellow arrow or yellow "X" for a slow lane, and a Red "X" for a lane that is shut down. "The demand for both wireless and load-switch LED Lane Control Signals is growing and USA Signal Technology has developed the most advanced intelligent signals in the industry," said Bob Stevenson, USA Signal's president and CEO.

With its own redundant power supply, separate water tight and dust-free enclosures for the LEDs and control electronics that are convection cooled, USA Signal Technology LCS' have greatly extended operating life. For these reasons, USA Signal Technology is able to warranty its LCS for an unprecedented 5 years.
