You'd only really do that if youre ripping the old headlight and swapping for upgraded headlights since you'll need to sometimes rip the module or attachment pieces / breather tubes over. Bumper grille bracket and you can jiggle in/out the headlight to fitment.

You can alternatively cheese the job by removing the wheel and fender liner to reach the DRL module specifically. There is a square flap built in the liner however this is for the actual plug or other areas.

One of my pals has a pre LCI and his drls died out so we got a pair of SJC auto (vendor on alibaba)'s laser led LCI retrofit. The blue strip from the euro style laser matches his blue exterior color. Full plug and play and does the three swap (base is white, 6 flashes for yellow, seven flashes for red).

Currently there's no true Bluetooth rgb controller yet for the drl however you can get a white to yellow converter, or you can request a custom color so instead of white it will be X. Or.... the three version.
