96B and 98B Series Signal - Direct Surface
Mounting
NOTE: When installing indoors, the 96B and 98B series
signals may be mounted in any position.
The 96B series signals are not supplied with a direct mounting
hardware kit but can be direct surface mounted using appropri-
ate hardware.
1. Insert a small flat blade screwdriver between the locking
mechanism and the lens. Gently push down and then pry
up, unseating the lens. Pull the lens up and off of the signal
mounting base, being careful not to damage the lamp.
2. Refer to Figure 2. Remove the two knockouts for the
mounting screws from the signal base. Place the 3 3/4”
(95mm) mounting gasket provided in the direct surface
mounting hardware kit on the mounting surface and mark
the center of the three holes in the gasket on the surface.
Remove the mounting gasket and drill a 3/8” (10mm) hole
at each of the marked positions.
3. Install the two rubber expansion plugs provided in the
hardware kit into the two outer holes in the mounting surface
as indicated in Figure 2.
4. Route the wire leads from the signal base through the center
hole in the mounting gasket and mounting surface. Refer to
the signal’s label for voltage rating.
5. Align the outer holes in the mounting gasket with the holes
in the surface. Insert the two screws with lockwashers
(provided in the hardware kit) through the two outer holes in
the signal base and align the screws with the rubber expansion
plugs as shown in Figure 2. Press the signal base firmly
against the mounting surface and tighten the screws.
96B and 98B Series Signals - Wiring
1. Connect the field wiring to the signal wiring using one of
the following applicable procedures:
96B Series: Using wire nuts (not supplied), connect the
field wiring to the signal’s wire leads as shown in Figure 1.
Polarity is not important. Insert the wires into an appropriate
electrical junction box (not supplied).
98B Series: Using wire nuts (not supplied), connect the
signal’s red positive (+) wire lead to the positive power source
wire, and connect the signal’s black negative (-) wire lead to
the negative power source wire. Polarity must be observed.
Insert the wires into an appropriate electrical junction box
(not supplied).
99B Series Signals - Magnetic Mounting

Non-Magnetic Surface
CAUTION
To prevent damage or loss, using the signal out-
side of the vehicle during high speed driving
conditions is not recommended.
Steel (magnetic) surfaces: To mount the 99B series signals on a
steel surface, simply mount the signal where required and insert
the adapter plug into the vehicle’s cigarette lighter socket. To
prevent possible scratching of the vehicle surface when installing
or removing the signal, tip the signal slightly before making or
breaking magnetic contact with the surface.
