Unless you know how to break open a housing, buy exact parts needed, solder, and then reseal, it's exactly how they intended it to be with these all in one non user friendly housings. They want you to buy the entire housing. And that's why this will be the last vehicle I ever buy that has this setup. I enjoyed them on previous vehicles but given the cost, and in the case of our specific vehicle, the lack of coverage on extended warranties, it's just a piggy bank rape waiting to happen.
In your case, I assume you mean the "DRL" they don't actually consider a DRL but call it something else to be edgelords, which you can always just ignore as long as your normal headlights and turn signals are functioning, but if not, then back to my original statement.
