In many vehicles, the front and rear signal lights work to create that distinctive hazard light pattern that lets other drivers know that you’re slowing down for some reason, or that you’re having a problem. Usually, the hazard lights operate on the same circuit as your other lights, but they’re controlled by means of a separate switch.
The hazard warning switch is usually located near the steering column, but not in the same area as your turn signals. This is so that you don’t turn them on by accident. Usually, the switches are operated by means of tabs that are pulled out to activate the lights and pushed in to turn them off.
When you activate the switch, all of the vehicle’s turn signals become illuminated and then start to flash in a highly visible pattern. A circuit is completed, and power is sent from the fuse block through a flasher to the lights. The flasher causes the lights to rhythmically flash at a steady pace. Assuming that your hazard light switch is working as intended, the lights will work even if the key isn’t in the ignition.
You should never let hazard light problems go uncorrected. Not only will you fail a motor vehicle inspection or a routine roadside check, you could be endangering other drivers who don’t see this essential warning sign. Our expert mechanics can diagnose problems with the lights or switch, depending on which one is faulty.
If your hazard lights aren’t working the way they should, you need to get them fixed immediately. Operating your vehicle with bad hazard lights is dangerous. You’re risking your safety and that of other drivers.
