Once the job is complete turn the headlights on to check operation. If the
is out, replacement is required.
Proper headlight operation is necessary for the driver of the vehicle to see
the road in front of them in dark conditions. A headlight that is out or dim present
a safety hazard which can be corrected easily and inexpensively. Headlights draw
a significant amount of amperage that can cause problems unless all electrical connections
are corrosion free, therefore inspection of these connections is necessary. A headlight
is dim because resistance causes full voltage to be restricted.
