Head lights illuminate the highway sufficient to permit safe night driving. These are usually provided two or more beams. One beam provides maximum illumination for driving. The other beam is so designed to permit its deflection to the ground and to the side of the road. This beam becomes essential to minimize glare when passing other vehicles on the road. The head light has two filaments for the above purpose, an upper beam and a lower beam. When the light switch is pulled out, the circuit from the battery to the head lights is completed. This circuit is through the foot selector switch. This switch has to positions, low beam and high beam. These are also called passing beam and high beam.

01 - LIGHTENING SYSTEM OF A CAR - TAIL LIGHTS

Back up lights are installed in many vehicles to provide means of signaling when reversing. These lights come on when the driver shifts into reverse gear. This closes a switch linked to the selector lever which connects the backup lights to the battery.

Flashing signals or turn sign lights on each side of the vehicle on the front and rear indicate to other vehicle drivers and road users, the direction in which the vehicle is about to turn. In operation, the lights are caused to flash about 80 times per minute.

The turn signal lights are so wired to operate in a flashing mode when the front and rear lights on the right and left sides are activated by the turn signal light switch assembly shown .Flashing of the twin signal bulbs is controlled by the turn signal flasher shown in the picture A bimetallic strip in the flasher causes the circuit to open and close. As the current flows through the bimetallic strip it heats up and expands and thereby opens the circuit. As the strip cools, it contract and closes the circuit again.
