THE LIGHTS ARE NOT
CONNECTED TO THE

BRIGHTNESS OF THE LIGHTS
WILL CHANGE WITH ENGINE
SPEED. AT IDLE THE LIGHTS
WILL DIM. AS THE ENGINE IS		NON-REMOVABLE
SPEEDED UP, THE LIGHTS		CONNECTIONS
WILL BECOME THEIR BRIGHTEST.

	CONNECTIONS
NOTE: IF WIRING INSULATED CLIPS WERE REMOVED FOR
SERVICING OF UNIT, THEY SHOULD BE REPLACED TO
PROPERLY SECURE YOUR WIRING.
