PERMANENT MOUNT INSTALLATION INSTRUCTIONS
IMPORTANT: Please read all of the following instructions before installing your new light.
1. 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.
2. Your new warning light comes complete with a foam mounting gasket, mounting
screws, lock washers, and well nuts.
3. For any models utilizing a flange mount base, please skip to Step 6.
4. This light come equipped with a combination base, allowing
the light to be either mounted on a 1/2" NPT conduit pipe or
permanently mounted. For NPT pipe, mount the light using
the threaded entrance hole in the base of the light, then skip
to Step 11. For the permanent mount, proceed to Step 5.
5. Carefully remove either the four screws near the base of
the lens and lift off the lens. Examine the inside of the base
and use a punch or drill to remove the knockouts present.
6. Next, you will need to drill the holes in your mounting surface. Place the gasket in the
exact position the light is to be mounted, and mark the holes on the mounting surface.
(NOTE: You might have to stretch the gasket slightly to find the location of the holes in
the gasket.) Take care to ensure that the gasket does not move while you are marking
each of the holes. Be sure to mark the center hole if you will be running your wires
through the mounting surface.
7. Remove the gasket and drill your holes
using an appropriate 3/8" drill bit.
CAUTION: If you are mounting the
light on a vehicle, and plan to wire it
through the roof of the vehicle,
remove the headliner from the inside
of the vehicle. If you do not remove
the headliner, take care so that you
do not drill through it.

If you are mounting the light on the roof of your vehicle, take extreme care to ensure that the magnet
is firmly seated on your roof, and that the pull of the magnet is sufficient to secure the light in place.
As the composition of the metal in the roofs of different vehicles may vary, as well as the contour,
texture and/or condition, Star cannot guarantee the ability of the light to remain in place upon a

• CAUTION: Please be sure to check that your cigarette plug outlet is properly fused.
Testing the light before this fuse is properly installed will void the warranty
on the light.
• Once the light is secured, route your cord such that it does not interfere with the vision
of the driver or the operation of any controls, including, but not limited to, the steering
wheel, gear shifter, and/or airbag.
• This light has been factory tested and approved. If the light fails to work when the
plug is inserted into the cigarette plug socket, twist the plug a few times to remove any
ash or other deposits that might be preventing a good contact from being made. If the
problem persists, check for a fuse inside of the plug itself. If present, remove the fuse
from the circuit, check to see if it has blown, and clean the lighter socket and contact
surfaces. Reconnect the fuse and test the light again.
SPECIAL FEATURES
These strobe lights have a number of features:
1. LED Diagnostic Indicator: The 242
contains an LED designed to flash when
the strobe tube should be flashing. If a
strobe light is not working, troubleshooting
is simple with this new LED. Simply
examine the circuit when power is applied
to it. If the strobe tube is not flashing, but
the LED is flashing, you have a bad strobe
tube. If the LED is not flashing, the circuit is
either not receiving the proper voltage, or
the circuit has failed.
2. Photocell: The 242 has a built-in photocell
which will automatically switch the light to
low power during “night” (or low light)
conditions when such a high intensity is
not required.
3. Pattern Select Jumper: The 242 lights have a jumper on the circuit allowing the end
user to select the desired flash pattern. Placing the jumper on pins 2 and 3 (the outer two
pins) will elicit a quadflash pattern, and placing the jumper on 1 and 2 (the inner two pins)
will produce a doubleflash pattern.
