Common Basic Circuit - Complete Circuit
As stated above, a complete circuit is the circuit from the electrical source, in the diagram below a battery positive (+), through the equipment load (bulb) and returning to the source low side connection (battery negative) (-).

The circuit illustrated below contains no means of control (switch) or circuit protection (fuse/circuit breaker).

Battery Operation - Discharging
As the battery is discharged the electrolyte becomes dilute and the plates become sulphated. The electrolyte will divide into both hydrogen (H2) and sulphate (S04). The hydrogen (H2) combines with oxygen (0) from the positive plate to produce water (H20). The sulphate combines with the lead (Pb) in both plates to form lead sulphate (PbS04).

A fully discharged battery contains plates covered in lead sulphate (PbS04) and the electrolyte is diluted to almost water.

Because HID lamps have no wire filament it's much more durable that a conventional filament type bulb.

HID lights service life is generally considered to be in the thousands.
