Mounting
Electrical Connections
1. Your new warning light comes complete with one foam mounting gasket, one wire
grommet, two wire splicing terminals (only one with the 257TSG and 257TCG), three
mounting screws, three lock washers, and three hex nuts.
2. These warning lights come equipped with a combination base, allowing the light to be
mounted on either a 1" NPT conduit pipe or permanently mounted. For NPT pipe, mount
the light using the threaded entrance hole in the base of the light, and then skip to the
Electrical Connections below. For the permanent mount, proceed to Step 3.
3. Before installing this light onto a flat surface, it is recommended that you seal up the pipe
mount hole with a small amount of RTV. This will help prevent water damage.
4. Using the base as a template, mark three holes (on a 2.975" radius) on the mounting surface.
5. Remove the base and drill a 7/32" hole in the marked spots.
CAUTION: Take care not to drill through the headliner of the vehicle below.
6. If your wires will not be routed through the mounting surface skip to Step 8. If you are
routing your wires through the mounting surface, drill a 3/8 “ hole in the center for the wires.
7. Remove the headliner from the inside of the vehicle, if applicable. Insert the enclosed
rubber wire grommet into the center hole and route the wires through the grommet.
8. Align the outer holes of the base with the holes in the mounting surface, install the
screws and nuts, and tighten until snug. If you are installing the self-grounding
257TSG or 257TCG, be sure to scrape away the paint under the head of one of the
screws so that a good electrical connection is made.
CAUTION: All of our DC powered warning lights are polarity sensitive. These lights are
polarity protected only if the appropriate fuse is used. All wires connected to the positive
terminal of the battery should be fused at the battery for their rated load. Testing the light
before this fuse is properly installed will void the warranty on the light.
1. Connect the black wire to a good chassis
ground.
(Please note: The 257 series is self-
grounding and the black wire is
connected to the base. Be sure to
scrape away the paint under the head
of one of the mounting screws so that
a good electrical connection is made.)
2. Connect the red wire to the positive side of
your power source through a switch and a
5 Amp fuse. Be sure to check your light for
proper voltage.
255TS/255TC and 257TS/257TC Pattern Programming
Prior to shipping these models are set for quadflash mode. You
can use an internal jumper on the circuit to change the flash
pattern to singleflash or doubleflash, if desired.
1. Remove the jumper from pins 2 and 3 and briefly touch it
to pins 1 and 2 (about 1 second) and release it. The flash
pattern will advance to the next pattern.
2. Repeat touching and releasing to scroll through the patterns:
Singleflash Doubleflash Quadflash
3. Place the jumper back on pins 2 and 3 when the desired
pattern is set.
