DRL not working
I have been told I need a new control unit module but there’s 2 per headlight and I’m not sure which is for which.

my indicator light works and when I unlock my car at night the light works. But in the day my DRL doesn’t work on one side and my sidelights don’t work when the cars running.

anyone experienced enough to know which one I need?
