One of the most important car components in your BMW is back up reverse lights so don’t neglect them. Reverse lights are usually used to warn other people and vehicles on the road that your vehicle is about to move backwards. These lights also provide illumination when your car is backing up therefore it is extremely important that reversing lights are always in working condition to ensure the safety of your car and others on the road. By law it is required that every vehicle should have at least one or two rear-mounted rear-facing reverse lights therefore reversing lights come as a standard on all vehicle brands including BMW, Mercedes-Benz, Vauxhall, Honda, Toyota, Audi, KIA, Opel, Cadillac and many others. Reverse lights on a vehicle must be white in color. You can always test on your reversing lights to be able to drive your car on public roads without fetching heavy fines. To test your reversing lights, turn the ignition switch to the “ON” position without starting it then put the transmission in reverse with the parking brake on. Once that is set, get out of the vehicle and look at the reverse lights, they should be illuminated.
In case if reverse lights do not come ON when you test it, there is something wrong with the bulb. In such a situation, you will receive a warning message on your instrument cluster indicating a failure of your BMW reversing lights. When it happens, the message says “Reversing light failure”.
All the rear lights including brake and turn signal share the same ground for wirings and bulbs for each side so if the rear ground was lost, the brake light could find it through the parking light circuit but the reverse light would not.
How to fix this issue?
Having a reverse light out may cause you to receive a ticket so if you are having problems with your reverse light, you might need to have it replaced. Whenever this warning message appears; it means that the bulb of your reverse light has fused or its holder has corroded. Where a bulb may fail due to completion of its normal lifespan, the bulb holder may be corroded due to moisture but mostly it is the bulb which fails unless the car has met an accident and the damage caused the bulb to fail.
