One of the important warning lights on a motor vehicle is the reversing light. The reversing light is normally encased in a compartment with a white or transparent plastic cover to distinguish it from the red brake lights. The reverse light is activated by the reverse light switch whenever reverse gear is engaged by the driver.
The operation of the reverse light is governed by the reverse light switch. This switch is located at or near the gear box on both manual and automatic transmission vehicles. Once reverse gear is engaged the switch sends an electrical signal that activates the reversing light or lights.
An obvious sign that the reverse light switch is not working is that the reverse lamps fail to illuminate when reverse gear is engaged. Before replacing the Brand> reverse light switch a check should be made to ascertain whether the reverse light bulb has blown. The bulb compartment should also be cleaned and the wiring and connections should be checked. Finally, the fuse should be examined to check whether it has been blown. If all of these tests prove negative, it is very likely that the problem lies with the reverse light switch itself and the only viable option is to buy a replacement part.
