Model LPXD Flash Pattern Compliances
The flash patterns listed as "Yes" (Y) in Table 7 comply with the SAE J845 flash
requirements and light output requirements. Patterns listed as "No" (N) do not
comply with these requirements. A non-compliant pattern should be used only
after the people you are trying to warn have been trained to recognize the pattern
as a warning signal. End users are responsible for choosing the flash patterns that
meet their jurisdiction's requirements.
