Q: Daytime running lights
Can the daytime running lights be turned on at night
Yes, your daytime running lights are actually part of your lighting system when all lights are on. Depending on the make and model of your car, the main difference is that the main headlights and tail lights will be off when the running lights are on. Without more details about the make and model of your vehicle, it is difficult for us to give instructions for how to check if this is the case or not.
