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
