Quick Tail Light Test
How to perform a single-handed bulb check while inside your car
A burned-out taillight not only is dangerous, it’s also an invitation for a traffic ticket. For quick and easy taillight testing, tape pieces of aluminum foil to the inside of your garage door directly behind each taillight. With the garage door closed, turn the key on to the accessory position, but don’t start the car (for obvious reasons).
Then, while looking in the side-view mirrors, turn the headlights on and see if the taillights are working properly. Check the brake lights, too, as well as the turn indicators and backup lights. You can leave the foil in place if you wish, or for more permanent peace of mind, add stick-on metal or plastic mirror tiles.
