The front drivers side daytime running lights on my 2016 Cx-5 have failed after two years and 38900 miles. You cannot replace the "bulb" for a few dollars. You must replace the entire light unit that includes low beam, high beam, turn signal, and daytime running lights (drl). This unit costs minimum of $400. 00 and up to $1200. 00 when installed by dealer. This is an exorbitant price to pay for a simple led bulb that should last longer than two years in the first place.
There are two problems with the turn signal. First and foremost, on vehicles that are equipped with led headlights and led daytime running lights, it is very hard to distinguish the turn indicator since it is an incandescent bulb, it is not as bright as the led daytime running lights that when they are illuminated and looking straight at the vehicle, it is hard to tell if the turn signal is activated. This could be fixed by extinguishing the daytime running light temporarily while the turn signal on the side which the indicator is activated. In addition, the front marker bulb is hard to distinguish from the side, it should be a separate bulb on the assembly. The rear marker light is much more pronounced and visible not only because it is an led bulb, but because it is a separate fixture from the turn signal amber combination lamp.
