12 Inch LED Traffic Signal Lamp Unit
1. Description. This specification describes the minimum acceptable design and performance
requirements for a twelve (12) inch LED (light emitting diode) traffic signal lamp unit.
2. 12 Inch LED Traffic Signal Lamp Unit.
(1) General. The LED traffic signal lamp unit shall be designed as a retrofit replacement
for existing traffic signal lamps without the use of any special tools for installation. The
LED unit shall fit into existing traffic signal housings without modifications.
Installation of a retrofit replacement LED unit into an existing traffic signal housing
shall only require removal of the existing lens, reflector, and incandescent lamp, fitting
of the new LED unit securely in the housing door, and connecting to existing electrical
wiring or terminal block by means of simple connectors.
Prominent and permanent directional marking(s), an "UP arrow," for correct indexing
and orientation shall exist on the LED unit, if proper orientation of the LED unit is
required for optimum performance.
The manufacturer's name, serial number, manufactured date (month and date) and other
necessary identification shall be permanently marked on the backside of the LED unit.
A label shall be placed on the LED unit certifying compliance to ITE VTSHS (Vehicle
Traffic Control Signal Head Standard).
Any deviation to product design after testing and approval from TxDOT shall consist of
a new model and must be resubmitted for acceptance. Failure to adhere to this
requirement shall be grounds for automatic removal from the TxDOT Qualified Product
List (QPL) for an undetermined time. Random testing of average production LED units
will be tested to ensure compliance with specification.
(2) Physical and Mechanical Requirements. The LED traffic signal lamp unit shall be a
single, self-contained device, not requiring on-site assembly for installation into existing
traffic signal housings.
The assembly and manufacturing process for the LED unit shall be such as to assure all
internal LED and electronic components are adequately supported to withstand
mechanical shock and vibration from high winds and other vibration sources.
Each LED unit shall comprise a UV stabilized polymeric outer shell, multiple LED light
sources, and a regulated power supply. LED's are to be mounted on a polycarbonate
positioning plate or conformally coated PC board.
1-6 1201
01-03

Optical and Light Output Requirements. The LED's shall be manufactured using
AIInGaP (Aluminum -Indium -Gallium -Phosphorous) technology or other LED's with
lower susceptibility to temperature degradation than A1GaAs (Aluminum -Gallium -
Arsenic) LED's. A1GaAs LED's will not be allowed.
The color of the LED traffic signal lamp unit shall be specified on the plans. Each LED
unit shall meet minimum laboratory light intensity values, color (chromaticity), and
light output distribution as described in ITE VTCSH part 2 of the specifications 6.4.2.1,

values in Table 1 of Section 4.1.1 of the ITE VTCSH. The 6.4.2.1 test shall include an
expanded view for the Red and Green Ball indications with the following minimums for
a period of 60 months, based on normal use in traffic signal operation over an operating
temperature range of -40°C to +74°C. In addition, yellow LED unit shall meet or
exceed the following minimum illumination values for a minimum period of 60 months,

greater than 40 percent. The LED unit, upon sensing a valid loss of light, shall present
impedance of at least 500 Kohms to the AC line.
Two, captive, color coded, 36 inches long, 600 V, 18 AWG minimum jacketed wires,
conforming to the National Electric Code (NEC), rated for service at +105°C, are to be
provided for an electrical connection.

Federal Communications Commission (FCC) Title 47, SubPart B, Section 15
regulations concerning the emission of electronic noise.
Environmental Requirements. The LED traffic signal lamp unit shall be rated for use
in the ambient operating temperature range of —40°C to +74°C.
The LED unit shall be dust and moisture tight to protect all internal LED and electrical
components.
The LED unit shall consist of a housing that is a sealed watertight enclosure that
eliminates dirt contamination and allows for safe handling in all weather conditions.
Moisture resistance testing shall be performed on the LED unit in conformance with the
requirements in NEMA Standard 250-1991 for Type 4 enclosures. Evidence of internal
moisture after testing shall be cause for rejection.
(6) Production Testing Requirements. Each new LED traffic signal lamp unit shall be
energized for a minimum of 24 hours at operating voltage and at a temperature of
+60°C in order to cause any electronic infant mortality to occur, and to ensure
electronic component reliability prior to shipment.
After the burn -in procedure is completed, each LED unit shall be tested by the
manufacturer for rated initial intensity at rated operating voltage.
