Daytime running lights, sometimes referred to as DRLs or DTRs, are lights that switch on automatically when your 2009 Mercedes-Benz C300 is turned on and in drive. Since the daytime running lights are on whenever you are driving your C300, they are often the first bulbs to burn out. The video above shows you how to change the daytime running lights in your 2009 C300. These bulbs grow dimmer by over 20% over time, therefore we recommend changing both bulbs on your C300 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 C300, 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.
