1.
Cleaning lenses and housings that are polycarbonate with solvents will result in the softening, crazing, and/or
cracking of the plastic. This is especially true of polycarbonate lamps and mounting bases, which may be under
stress in their normal applications. The following cleaners are compatible with polycarbonate (not a complete
list):
a.
Mild soap and water
b.
Mineral spirits
c.
#1 and #3 denatured alcohol
d.
White kerosene
e.
Methyl, isopropyl, and isobutyl alcohols
f.
Polycarbonate cleaners
2.
The following must NOT be used to clean polycarbonate (not a complete list):
a.
Acetone
b.
Gasoline
c.
Carbon tetrachloride
d.
Liquid detergents
e.
Stanisol naphtha
f.
Oils
3.
All lamps will last longer if they run cool. Dirt on the lens increases the heat, so keep them as clean as possible. Other
people must see your semitrailer and that is one of the purposes of the lighting system: to be seen.
TIPS TO PROLONG LIGHTING LIFE

WARNING
Certain lighting products generate heat. Care should be taken to avoid contact with flammable
materials. The unit can generate enough heat to cause injury to personnel or damage to
the equipment.
1.
Never use a test probe to pierce wire insulation when troubleshooting lighting problems. Wicking action takes
place which causes moisture to travel along the wire strands and corrode critical connections. If probing harness
or wire is necessary, make sure the puncture is completely sealed.
2.
To correct voltage problems, discover the real cause. Under-voltage is often caused by poor connections. To correct
under-voltage, do not just increase the voltage; find out what caused the under-voltage.
3.
Many discarded lamps are still in good condition.
