Daytime running lights, sometimes referred to as DRLs or DTRs, are lights that switch on automatically when your 2015 Audi A3 Quattro is turned on and in drive. Since the daytime running lights are on whenever you are driving your A3 Quattro, they are often the first bulbs to burn out. The video above shows you how to change the daytime running lights in your 2015 A3 Quattro. These bulbs grow dimmer by over 20% over time, therefore we recommend changing both bulbs on your A3 Quattro at the same time, even if only one bulb is burnt out - this will allow both DRL bulbs to have the same intensity and prevent the old DRL bulb from appearing dimmer than the new one.
When you change the daytime running light on your A3 Quattro, it is important not touch the glass part of the bulb with your fingers because the oil from your fingertips will cause that part of the bulb to burn hotter, which significantly shortens the life of the bulb. Some studies indicate that driving with your lights on can reduce accidents by 18 - 34%, driving with your DRLs or headlights on the day can reduce your chance of getting in an accident.
