Chapter 5: Servicing the Lightbar
QUALIFICATIONS
To properly service a lightbar, you must have a good understanding of automotive
electrical procedures and systems along with proficiency in the installation and use of
safety warning equipment.
Establishing a regular maintenance schedule for the LED
JlX
extends the life of the lightbar
and ensures safety. Periodically check that the lightbar operates properly and that all mounting
hardware is securely fastened to the vehicle. Also, inspect the domes and reflectors for cracks,
crazing (hairline cracks), discoloration, and other defects.
This chapter has information for replacing components such as lamps, printed circuit boards
(PCBs) and fuses. For service, support, or replacement parts, contact the Federal Signal Service
Department at 1-800-433-9132, 7

Cleaning the Plastic Domes
CRAZING/CHEMICALS
Crazing (cracking) of domes 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 domes does occur, the reliability of light for
emergency signaling purposes may be reduced until domes are replaced.
Failure to follow this warning can damage the domes and may result in bodily injury or
death to you or others.
1. Rinse the domes with lukewarm water to loosen dirt and debris.
2. Use a mild soap, lukewarm water, and a soft cloth to gently clean the domes. To avoid dam-
aging the lens, do not use heavy pressure or caustic, abrasive, or petroleum-based cleaners.
3. Rinse, then dry the domes with a soft cloth to prevent water spotting.
4. To remove fine scratches and haze, use a specialty plastic cleaner/polish and a soft cloth.
You can also use a high quality automotive paste cleaner/wax that is non-abrasive.
The most effective product you can use for cleaning, protecting, and polishing clear and colored
plastics is Plexus® Plastic Cleaner, Protectant & Polish. Over time, exposure to heat, sunlight,
and smog causes plastic to fade, discolor, scratch, or become brittle. Plexus seals the pores
of the plastic, making the plastic easier to clean, improving scratch resistance, and increasing
product longevity.
