Experienced mechanics share their insights in answering this question :
Hi there. If you are having problems with a reverse lights, it is possibly due to a reverse shift sensor or damaged electrical relay that powers the light. It’s also possible that you have an exposed wire that’s causing this issue. You might want to have a professional mechanic complete a light not working inspection to determine what is causing this issue.

First check that the bulbholder and wiring terminals are clean and bright. If there is any corrosion, clean it up with wet-or-dry paper then refit the bulb and retest. If the bulb still fails to light, the fuse may have blown. You should also suspect a blown fuse if two reversing lights go together.
The back up light fuse is located in the underhood fuse and relay box. It feeds the lighting control module. Check that fuse first. Beyond that could be a control module issue or a broken wire.
While there is usually a legend in the fuse panel lid, a more detailed version is usually in the owner`s handbook, and, this may help as some fuses supply more than one item in many cases. There should be a fuse panel behind the coin tray, fuse 18 is for reverse lights.
The gearbox pushes it down (pushing the switch) when in forwards gears which opens the circuit and turns the lights off. In reverse it lifts up and closes the circuit which turns the lights on.
The backup light switch is the electronic switch on a vehicle that is responsible for activating the vehicle`s reverse lights. The switches work by activating the lights when the transmission is put into reverse gear.
The fuse is actually under the USM module which is located to the right of the 12v battery under the bonnet…
Reverse light relay wiring
You usually don`t need a relay for power consumption under 60 watts. If your aux lighting is more powerful than 60 watts, you need one standard Bosch relay. With this method, diodes are not required.
7 pin electrics also don`t provide power for the reversing lights on a caravan or cycle carrier, the power for the reverse light comes from the caravan side of things, so it`s only provided in twin or 13 pin electrics.
A backup light switch screws into the transmission and is triggered when you shift the vehicle into reverse. If the switch is functioning normally, a circuit is completed when the switch is triggered and the white lights in the tail lights will illuminate, indicating to other drivers that you are backing up.
An automatic transmission reverse light switch is generally integrated in the Range selector switch and even though the total range selector switch is generally more complex in operation, the reverse switch function remains the same for both manual and automatic transmissions.
noun. : an electric switch that has four terminals capable of being connected in pairs in two different ways so as to reverse the direction of current flow.
The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.
If you were using dual intensity bulbs like for a stop/turn/running light circuit you would need a 3-wire pigtail to provide the voltage for the second circuit. Basically, one wire is the ground and the other wire(s) represent the other circuits.
What does ACG mean? It stands for “alternator circuit generator.” The fuse is responsible for protecting the alternator circuit and the alternator itself from overcurrent. If the ACG fuse blows, it can cause the alternator to stop functioning, which can have severe consequences for the vehicle.
Heater Fan, Brake Lights, Reverse Lights, Hand Brake Switch – Fuse 2 – 15 amp.
Electrical Issues
If you have a malfunctioning tail light, it could be a matter of a blown fuse. The fuses work with your car`s electrical panel and if they`re blown, it can cause several lights to stop working. Replace the fuse and see if this helps. Another issue may be related to your wiring.
Check the fuse.
A blown fuse usually causes both lights to go out. On newer cars, the tail lamps can be fused separately and/or each bulb or shared circuit can be fused. A fuse can be blown due to other problems, so you`ll need to check more than just the fuse, but it`s the right place to start.
It is a 15amp fuse that powers the stop light switch on the brake pedal. The brake light switch sends power to rear brake lights.
Three wires will be attached to your switch: a hot (black) wire, a neutral (white) wire and a ground (copper) wire.
The reverse trigger wire is providing a signal to your head unit to indicate that the vehicle has been shifted into reverse. In the previous section, we made this connection to the back of the vehicle`s head unit.
Replace the fuse with the same type and Amperage rating as the original. IMPORTANT: These fuses protect the converter from damage in the event that the RV battery is accidentally connected in reverse. A reversed battery connection, even if for only a second, will cause these fuses to blow.
The use of a schottky diode should solve this problem in almost all cases, however. The advantage of this solution is that the added diode has no effect in normal operation and still provides protection in a reverse polarity situation.

Reverse Power Relay is a directional protective relay that prevents/protect the generator from motoring effect (going to reverse direction). It is used where generator runs in parallel with other utility or generator.

Electrical wiring issue with the dash lights.
ANSWER : Check the lights on the dash and look for the wiring. Follow the wires to where they hook up to and check that component to see if it’s working. Most dash lights are hooked into the light switch and on the terminal for the dimer lights rheostat. If you replaced the light switch, then there is a break between the light switch and the dashboard light. If you need further assistance with the dashboard lights not working, then seek out a professional, such as one from Your Mechanic, to help you.
All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be. If you need more assistance with repairing your vehicle please keep in mind that our organization provides Mobile Mechanics who can help you diagnose and repair your vehicle, all at competitive rates.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.
EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.
Reverse lights won’t turn on when I put it in reverse. Dark blue wire has power, light green (reverse) wire has no power.
ANSWER : Hi there. Remove the fuse to the reverse lighting system. On the side that does not have power, use a digit ohm meter and check for resistance. The meter should read OL (out of limits). Now, turn on the ignition key to the ’ON’ position, set the parking brake and chock the wheels, and put the transmission in reverse. Check the connection again for resistance. There should be a resistance of 5 ohms or less. If the meter reads OL, then there is a break in the wiring from the fuse box to the switch. Since you disturbed the fuse box, there could be a wire that is loose or broken that goes to the reverse lights. If you need further assistance with your reverse lights not working, then seek out a professional, such as one from Your Mechanic, to help you.
Van keeps blowing fuses, no lights in back work, can’t shift unless key is in certain position
ANSWER : There is a short somewhere, causing the fuse to blown continuously. In your vehicle, power flows from the ignition switch to the transmission range sensor. This sensor needs to be operation in order for the transmission to be moved out of park, as does the ignition switch. Since your headlights always stay on, there is obviously a short somewhere in that circuit. This kind of problem will require firsthand professional diagnosis from a professional. I recommend calling YourMechanic to diagnose and repair this electrical problem since we come to your home or office.
My front flashers turn signals and brake lights dont work. I have replaced the bulbs and checked the fuses. What could cause these
ANSWER : The different lights all go through the turn signal light turn switch. If the brake light switch is not working at all then the third brake light would not work. You will need to replace turn signal switch and check brake light switch also and replace it if no third brake light is working.
