Front left DRL acting up
So recently my car randomly says that my front left DRL(daytime running lights) is not working and when i look at it, it is actually off and only my right one is working. Most of the time there is no error but randomly it will do it. I think its due to my recent upgrade to LED white bulbs for the license plate lights that could be making it throw the error.
What do you guys think? Do i need to get the voltages or something reprogrammed?
Thanks in advance

I have had aftermarket LED DRLs stop working on me, though the connector plug the bulb sits in can be a little on the temperamental side. Ensure that you are getting the DRLs with integrated load resistors as LEDs will otherwise cause an error code due to the very low voltage they draw. You might start by pulling the plug out with the DRLs on and see if the bulbs were too loose. Seating them fully in the plug was not necessarily the optimal location to ensure a positive connection, or so I found it to be the case.

I have the DRLS up front switched out to LED as well as the license plate bulbs and have no issues whatsoever. I don't quite know how the rear bulbns would affect the fronts. Can you confirm you used ones with load resistors?
