Having any of the lights on your car not functioning properly is dangerous. Be sure to check your turn signals, brake lights, reverse lights, and of course your headlights on a regular basis. Although you are likely to catch a headlight that is out, you could easily miss a brake like or taillight that doesn’t function right. These things are vital to letting other vehicles know what you are doing or about to do – and preventing accidents. You could also get a ticket for having a light out, which could mean higher car insurance rates.
