B, C and D; Class II, Division 2, Groups F & G; Class III or non-

Federal Signal Model 371LEDX-120 warning light incorporates an
array of high power LEDs, a custom optic, and a rotating reflector to
focus a beam of light that rotates 360 degrees within a plastic dome.
The Model 371LEDX-120 features a impact-resistant plastic
dome. The Model 371LEDX is available in five colors: amber,
blue, clear, green, and red. The dome-and-ring assembly screws
on, providing access to the interior of the light. The base features
textured black powder paint for greater corrosion-resistance.
Wiring can be routed through the pipe-mount opening in the
bottom of the light or the two side knockouts can be used for side
entry wiring. Installation can be surface or 1-inch NPT pipe mount.
An optional reflector is available that reflects the light beam at
22.5 degrees from the vertical orientation for overhead mounting
and other applications. See Figure 1 on page 7.
Also available is an optional wall-mount bracket. The LHWB
wall-mount bracket can be used to mount the Model 371LEDX.
For surface mounting on solid substrates, the separately purchased
Model 371BRCKT three-point surface-mount bracket is available.
Unpacking the Light
EXPLOSION HAZARD — Damaged domes can lead to explosions
that could result in serious injury or death. If the dome is
damaged in any way, it MUST be replaced.
After unpacking the light, examine it for damage that may
have occurred in transit. If the light has been damaged, do not
attempt to install or operate it. File a claim immediately with
the carrier, stating the extent of the damage. Carefully check all
envelopes, shipping labels, and tags before removing or discarding
