Reverse light bulbs: operation features

Reverse light bulbs are very important signaling elements that indicate the direction of the vehicle movement. Their use is regulated by the traffic law and their proper operation is a must. Reverse lights of modern vehicles are most often fitted with conventional or halogen filament bulbs.

Tips on how to choose, use and replace them

  • Before buying reverse light bulbs, make sure that their parameters comply with the specifications of the standard equipment, otherwise, it will be impossible to mount the part. For example, the C21W bulbs have two bases, while the P21W and H6W – one.
  • The average service life of these products depends on their type, rated power, luminous efficiency, and varies in the range of 500–1,250 hours. However, this is true only in case you use the products made by famous manufacturers.
  • Pay your attention to the colour temperature. The higher it is, the more intense is the light emitted by the component. The shells of some products are blue. This helps to obtain whiter and more intense light, which is important when, for example, the vehicle is equipped with a reversing camera, as in that case the area behind the car can be well lit.
  • Before installing LED bulbs into reverse lights, make sure that this replacement is legally possible. Despite the fact that these components are offered in the product range of many manufacturers, most of them are not certified by the ECE. That’s why it is prohibited to use them on public roads in Europe.

Malfunctions of reverse light bulbs, their causes and symptoms

  • Burning-out. Due to the evaporation, the tungsten filament gets thinner with time and eventually breaks down. Its premature burnout can be caused by its poor quality or voltage changes in the electrical system. A blown bulb cannot emit light and, as a consequence, the reverse light won’t switch on.
  • Bulb blackening. Particles of evaporated tungsten deposit on the inner surface of the glass, which results in it blackening. In the case of halogen-type items, the soot formation can be caused by installation errors like touching the glass bulb with bare hands.
  • No contact. A broken electric circuit prevents the filament from being supplied with power, due to which the lights don’t work.
  • Damaged bulb shell. In case of a car accident, collision or careless parking, the lamp might be broken.
