Lights and Signals

Your vehicles light system is your primary means of communicating with the world outside your car and it is your best tool for seeing and being seen. The light system includes both interior and exterior lights. 

Most of the interior lights are found on your dashboard and were discussed before. Other interior lights may include a dome light and reading lights. Many drivers prefer that all interior “comfort” lights remain off while driving because they may affect the driver’s night vision or produce unnecessary glare. 

Exterior lights include headlights, taillights, brake lights, turn signals, parking lights, emergency flashers, and in some cases side marker lights and mirror-mounted signals

Keep your exterior lights clean and check them once a week to make sure they work. Dirty lenses can reduce light output by up to 90%.
