THE LIGHTS ARE NOT

 

 

 

 

CONNECTED TO THE

HEADLIGHTS

OWN ELECTRICAL SOURCE.

 

BECAUSE OF THIS, 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.

 

 

 

 

WIRING INSULATED CLIPS

REMOVABLE

CONNECTIONS

NOTE: IF WIRING INSULATED CLIPS WERE REMOVED FOR

 

SERVICING OF UNIT, THEY SHOULD BE REPLACED TO

 

PROPERLY SECURE YOUR WIRING.
