Daytime Running Lights Replacement: 1999 Chevrolet Express 2500 4.3L V6 Standard Cargo Van

Daytime running lights, sometimes referred to as DRLs or DTRs, are lights that switch on automatically when your 1999 Chevrolet Express 2500 is turned on and in drive. Since the daytime running lights are on whenever you are driving your Express 2500, they are often the first bulbs to burn out. This video shows you how to change the daytime running lights in your 1999 Express 2500. You may get a warning light that the Chevrolet DRL system needs attention when one side of the DRL lights in your Express 2500 is not working. These bulbs grow dimmer by over 20% over time, therefore we recommend changing both bulbs on your Express 2500 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. You may want to consider replacing your burnt out DRL with LED daytime running lights for optimal longevity.
