Maintaining the Rear ILS
Maintaining the Rear ILS
Establishing a regular maintenance schedule for the ILS light bar extends its life and
ensures safety. Periodically check that the light bar operates properly and that all
mounting hardware is securely fastened to the vehicle. Inspect the reflectors for cracks,
crazing (hairline cracks), discoloration, and other defects.
PERIODICALLY CHECK GLASS: The effectiveness of the Rear ILS depends
on the clarity of the glass it is being placed behind. Dirt and defects in
the glass reduces the light output. The reliability of light for emergency
signaling purposes may be reduced if the glass is dirty, cracked, or not clear.
Periodically check the glass for cleanliness to ensure maximum light output of
the Rear ILS light bar.
Cleaning the Shrouds
To clean the shrouds:
1.
To remove the light bar from the vehicle, refer to the vehicle-specific installation
instructions that come with the ILS light bar.
2.
Use a soft tissue to clean the shroud. If needed, you can use a solution of mild soap
and water, but take care not to get water on the PCBs.
3.
When finished, make sure the light bar is completely dry before reinstalling it
according the vehicle-specific installation instructions.
Cleaning the Reflectors
CRAZING HAZARD: Crazed, cracked, or faded domes or reflectors reduce the
light output and the effectiveness of the lighting system. Tops or reflectors
showing this type of aging must be replaced. Failure to follow this warning
may result in bodily injury or death to you or others.
CLEANING SOLUTION WARNING: The use of cleaning solutions, such as
strong detergents, solvents, and petroleum products, can cause crazing
(cracking) of the domes and reflectors. Failure to follow this warning can
damage the domes and reflectors and may result in bodily injury or death to
you or others.
To clean the reflectors:
1.
To remove the light bar from the vehicle, refer to the vehicle-specific installation
instructions included with the Rear ILS.
2.
Use a soft tissue to clean the reflectors. If needed, you can use a solution of mild soap
and water, but take care to avoid getting the PCBs wet. Avoid heavy pressure and the
use of caustic, abrasive, or petroleum-based cleaners, which will scratch or dull the
reflectors.
