Have you ever found yourself frantically searching your car for a working light while the battery is dying? Maybe you’ve had to call a tow truck because you can’t find your way home in the dark.
With so many people relying on car lights to help them get around, it’s no wonder that manufacturers have developed technologies to keep drivers safe and informed when their battery is low. In this article, we’re going to take a look at some of these technologies and see how they work.
What are Car Lights Pulse?
Car lights pulse when there is a bad battery connection. This happens when one of the car’s electrical systems isn’t getting enough juice to keep the lights on. When that happens, the car’s computer will try to keep everything running by turning on and off the car’s lights.
How to Test if Your Car Has a Bad Battery Connection
The most common problem with car batteries is a bad connection. If your car won’t start, or if it starts but dies after only a few minutes, the battery may be the issue. Here’s how to test if your battery is bad:
1. Make sure your car is off and unplugged.
2. Remove the battery connector from the battery.
3. Touch two metal surfaces together (like the terminals on a battery) and see if you get an electricity spark. If you do, your battery is probably bad and needs to be replaced.
How to Fix a Bad Battery Connection in Your Car
If your car’s battery is not holding a charge, the dashboard lights may pulse or flicker. This is due to the car trying to run on its alternator instead of its battery. There are several ways to fix a bad battery connection in your car.
The easiest way to check if you have a bad battery connection is to try and start your car with the key in the off position. If you can’t start your car, then you likely have a bad battery connection.
If your car does start, then you will need to test your battery for voltage. You can do this by using a voltmeter or by testing your car’s battery cable. If your voltage is below 12 volts, then you likely have a bad battery connection.
If your car doesn’t start even after trying to start it with the key in the off position and testing your voltage, then you will need to replace your battery.
Conclusion
If your car’s headlights start pulsating, it could be because of a bad battery connection. This can happen when one of the battery terminals becomes loose or corroded, preventing the electrical current from flowing properly through the cable. In most cases, this problem can be solved by re-connecting the battery cables and resetting the car’s computer system. However, if this doesn’t work and you’re still experiencing pulsing lights, it might be time to get a new battery.
