SMC16 Control Unit (+12Vdc activation via
user-supplied switch).
See figure 2. Connect the ten-conductor cable’s
blue lead to ground. Connect the white lead to ground. Connect
the pink lead to one side of a user-supplied switch (one-ampere
minimum). Connect the other side of the switch to +12Vdc. The
flasher will operate upon activation of the user-supplied
switch.

SMC16 Control Unit (ground activation via
user-supplied switch).
See figure 3. Connect the ten-conductor cable’s
blue lead to ground. Connect the pink lead to +12Vdc. Connect
the white lead to one side of a user-supplied switch (one-
ampere minimum). Connect the other side of the switch to
ground. The flasher will operate upon activation of the user-
supplied switch.

MAINTENANCE.
A.
General.
WARNING
Crazing (cracking) of lenses will cause reduced
effectiveness of the light. Do not use cleaning agents
(which will cause crazing) such as strong detergents,
solvents, or petroleum products. If crazing of lenses
does occur, reliability of light for emergency signalling
purposes may be reduced until lenses are replaced.
Ordinary cleaning of the plastic lenses can be
accomplished by using mild soap and a soft rag. Should fine
scratches or a haze appear on a lens, they can ordinarily be
removed with a non-abrasive, high quality, one-step, automo-
tive paste cleaner/wax and a soft cloth.
B.
Lamp Replacement.
WARNING
A serious injury may result if lamp is touched when
hot. Always allow lamp to cool before removing.
Halogen lamps are pressurized and if broken can
result in flying glass. Always wear gloves and eye
protection when handling the lamps.
CAUTION
Use of higher wattage lamps can result in damage to
the colored lenses.
1.
See figure 4. Remove and retain the two screws
which secure the lens. Carefully pull the lens straight away
from the light assembly.
CAUTION
Service life of lamp will be shortened if glass is
touched. If glass has been handled, clean with a
grease solvent.
2.
Remove the defective lamp by carefully pulling it
out of the socket. Install a new lamp by aligning the pins on
the lamp base with the holes in the socket, and carefully
pushing the lamp into the socket.
3.
Replace the lens using the previously removed
screws.
