The instrument cluster is lit to have necessary visibility by adjustable LED from the back. Each 
indicator of instrument cluster is lit by special LED. All LED are wholly welded to the circuit board 
at the back of the cluster housing. The instrument cluster is connected to the electrical system of 
the complete vehicle with connecting circuits, which are integrated into the vehicle harness and go 
along different paths, secured in varied ways.
