Light ON For through-
beam and retro-
reflective:
connect the
white wire (Pin 2)
to the brown wire
(Pin 1).
For diffuse-re-
flective:
open (do not con-
nect) the white
wire (Pin 2).
Dark ON For through-
beam and retro-
reflective:
open (do not con-
nect) the white
wire (Pin 2).
For diffuse-re-
flective:
connect the
white wire (Pin 2)
to the brown wire
(Pin 1)
