Why are the lights on my car not working?
Corrosion or bad connections in the power circuit. Headlamps or bulbs are worn out. Damaged wires in the circuit. Low charging system output. Make sure the headlight lenses are not foggy. Light bulbs, also, may also be worn through years of service. You may notice that your headlights dim in a particular engine operating condition.
If one or both headlights don’t work after you replace the bulbs, check the fuses. The low beams and high beams have their designated fuses for each of the circuits. In some car models, you will have a separate fuse for the left and right low beams. Locate the fuse box under the engine and by the dashboard.

What happens when one of the headlights is not working?
When one of the headlights is not working, the bulb of the faulty lamp may have burnt. The lifespan of bulbs is limited and this is greatly dependent on usage as well as magnitude of vibration they are exposed to. There is no way the tungsten filament in the incandescent bulb will not burn out.
What should I do if my headlight bulb fails?
If you have multiple headlight bulb failures, make sure you are especially clean when doing the job. If at all possible, don’t touch the glass portion of the bulb at all. If necessary, handle the bulb with clean latex or nitrile gloves. Finally, if the bulb is dirty, clean it with a fresh alcohol pad before installation.
Why are my high beam lights not working?

Where do you change the headlight bulbs in a car?
In the majority of today’s vehicles, headlight bulbs are usually replaced through the housing at the back. In some vehicles, it is easy to access the housing while in others, you will have to do away with some components which may make the access to be difficult.
Most headlight failures are caused by a blown a fuse. Other common problems include bad relay, switch, or module. Wiring problems, especially inside the headlight, can also cause a headlight to stop working.
How can you tell if a fuse is good or bad?
You can’t in general tell if a fuse is good just by looking at it. Also, just because you hear clicking when you turn the headlights on doesn’t necessarily mean the headline relay is working or even that it is the relay doing the clicking. I think there are separate fuses for both left and right, so two bad fuses seem unlikely.
How can you tell if a light bulb is not a headlight?
Look at the wiring diagram and go through it point by point with a test light and DVM. I’d start at the headlight connectors. Is voltage getting there? If not, then you know it’s not the headlight bulbs. Then work your way back towards the relay. It could just be a loose or corroded connector somewhere between the relay and the headlights.

Why does my Hagerty relay not show continuity?
If the relay does click and 30 and 87 do show continuity, there is still the possibility that the internal contacts are corroded and a voltage drop across them is preventing full current from flowing. Take that thought and park it for a moment. If the relay itself tested as good, then the relay wiring must be tested next.
When do you need to troubleshoot a relay?
That is, on a horn, 12V should always be present on 86, and 85 is grounded when the horn button is pressed). If the control side fails either of these tests, you must troubleshoot the wiring. Often it is a problem in whatever is switching the control side on and off.
What happens when you touch 86 and 85 on a relay?
When you touch 86 and 85 to the battery, the electromagnet pulls the switch contacts together, so the resistance between 30 and 87 should read essentially zero (under one ohm). If it doesn’t, the relay isn’t working.
If still no luck, with the GEM apparently working, the switch will be ok if thr GEM is working, the fuses are ok, then we are looking at a potential wiring fault between the GEM and the bulbs themselves. But i would recommend having the actual output of the GEM checked first before getting to hung up on wiring checks.
Why are the lights not working in my car?
OK if the fuses are definatly ok, and the bulbs are fine, then is going to be either th headlamp switch or the GEM at fault. The GEM controls all the ancillary electronics, this is disguised as the fuse box of which you checked the fuses in the passenger footwell.
Typically, a headlight switch would need to be tested if the headlight is not working properly, as power is transferred from the switch to the fuses. Prior to that, however, in case this is a halogen system, the bulbs should be checked and changed if needed. To troubleshoot the headlight switch, it should be removed.
Why do I have problems with my VW headlight?
Headlights are a must for every vehicle for safety reasons. A hindrance in power supply can cause havoc with the internal lighting in the VW headlight and related problems can arise due to bulb issues or fuses, wiring or harness overheating within the assembly.

Owners may be able to fix some of these problems themselves, however, when assistance is needed it is vital to know where to find fast, affordable guidance.
What should the voltage be on a Volkswagen headlight?
If the voltage results match, it should be measured between brown and gray/blue pins. With the headlight switch and ignition key on, the voltage should vary from 0-12.0 volts based on the position of the switch. If the reading is varied, the faulty headlight switch should be replaced.
How do you check for a bad ground on a headlight?
Turn off the ignition and headlights. Set the multimeter to measure resistance (ohms). Place one lead on the chassis or the negative terminal of the battery, and the other lead to the ground wire. If the resistance shows continuity (zero resistance) then the wire is okay. Otherwise, go to the next step. Check the resistance of the wire.
