3 Main Causes of Car Hazard Lights Not Working
The term hazard lights in vehicles is still not widely recognized. In fact, this component is related to the turn signals or turning signal.
For those who are not familiar with hazard lights, please read the following review Understanding the Function of Hazard Lights and How to Use Them. Usually, when the car's hazard lights are off, it is also related to the turn signals. If this happens to your vehicle, try checking the following 3 parts.
1. Broken Light Circuit
If the emergency lights, which are also the same as the turn signals, are off, then the problem is most likely due to a broken circuit or a burnt-out bulb. When you press the hazard switch, which is generally marked with an exclamation mark, the indicator light on the dashboard and all four turn signals should light up simultaneously.
However, if the turn signals are off, it could be that they have reached the end of their lifespan or need to be replaced. You can confirm this by checking the light fuse circuit.
If it is still properly connected and not broken, then you need to buy a new bulb. The cause of the car's hazard lights being off due to a broken circuit can also be checked by yourself.
What needs to be noted is checking the fuse on the wire. Generally, this light has a current of 10 amperes.
So if the current is excessive or nonexistent, it will cause a short circuit and result in the circuit being off. If this problem occurs, then replace the entire circuit, not just the fuse. This is done to avoid fire due to overheat.

2. Drop Voltage in the Lights
When the hazard lights are turned on, all four turn signals should light up and blink together. However, if the lights blink too quickly and not in sync, then there is something wrong with the components.
This indicates that the main cause is due to a voltage drop in the circuit or the lights themselves.
The cause of the car's hazard lights being off occurs because the battery's electrolyte voltage has dropped. As a result, the flasher is lacking current and causes an unstable current supply.
To ensure a drop voltage has occurred, you can turn on the headlights or the horn. If the lights seem dimmer and the horn is not loud, then the voltage has indeed dropped.
You can resolve this by recharging the still-good battery. If the electrolyte battery is quite old and it is time to replace it, then it is better to replace it with a new one.
This is certainly related to the type of battery; if you are using a dry type, then you must replace the entire battery.
3. Issues with the Flasher Component
The cause of the car's hazard lights being off or not turning on at all can occur due to damage to the flasher component.
This component is responsible for supplying and interrupting the voltage, so the lights will blink.
The solution for repair is to replace it with a new flasher and ensure that the component has a normal voltage of 12 volts.
At least those are some of the causes of issues with the hazard lights. Whether the turn signals are completely off, not lighting up together, or not blinking, these problems can occur due to damage in the components.
Whether due to a broken bulb, flasher damage, or voltage drop. Make sure you check and fix it immediately.
