If it’s still dimmer after switching left-right, it’s because of the parameters in the headlight control module (the controller on the bottom of the headlight that you just replaced). To check the parameter, you need a software & hardware for coding.

The parameters for brightness are saved in the control module, rather than the DRL modules themselves, which are simply mechanical parts. However, even with the same parameters in the control modules, the brightness of the LED on DRL modules can vary depending on their age or manufacturer, especially if they are not OEM.
I absolutely have no knowledge in that kind of stuff.
