II. MAINTENANCE
A. General
Crazing (cracking) of lenses will cause
reduced effectiveness of the light. Do not
use cleaning agents (which will cause craz-
ing) such as strong detergents, solvents, or
petroleum products. If crazing of lenses does
occur, reliability of light for emergency sig-
naling purposes may be reduced until lenses
are replaced.
Clean the plastic lenses with a mild soap and a
soft rag. Remove fine scratches or haze with a non-abrasive,
high quality, one-step, automotive paste cleaner/wax and a
soft cloth.
B. Lamp Replacement
1. Remove the four screws from the endcap opposite
the cable entry.
2. Remove the endcap to allow the lightheads and
spacers to move freely.
3. Remove the defective lighthead by carefully discon-
necting it from the wire harness.
4. Connect the new lighthead.
5. Reset all lightheads and spacers into their original
locations.
6. Secure the endcap with the four screws removed in
step 1.
