Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles first sold in Canada. A light sensor on top of the instrument panel makes the DRL work, so be sure it is not covered. The DRL system will make your reduced intensity high-beam headlamps come on in daylight when the following conditions are met: When it is dark enough outside, the exterior lamps will come on automatically. When it is bright enough outside, the exterior lamps will go out and the DRL will turn on. Of course, you may still turn on the headlamps any time you need to. As with any vehicle, you should turn on the regular headlamp system when you need it.
