So you need to test your reverse lights, but you don't have a helper around to let you know if they are coming on. It's daylight so you can't tell by looking in your rear view mirror. What do you do? The answer is simple, but many people don't know their car works this way.
To test your reverse lights, turn the ignition key to the "ON" position, the spot where all of the dash lights come on but before you start it. Now put the transmission in reverse. If you have an automatic transmission, you might have to press the brake to release the shifter (a safety setting). Once you have the car in reverse, and the parking brake is on, you can get out of the car and have a look at the rear end. If you see two bright lights staring at you, all is well.
If one or more of your reverse lights is not working, you'll need to replace a bulb or two. Don't worry, we can show you how to do that, too.
