Since it draws power from the battery in the first place it will impact its life. Because the alternator won’t produce enough current at slow speeds(considering the slow pace riding or heavy traffic conditions).
Then it put on load on the alternator that consumes a little more on engine output (you can experience a mild drop in idle speed on switching on the headlights)
In my opinion a good led drl is enough to aid in visibility in daylight( like plating or dio). So l would like to have it only when required. Auto headlight on is a most welcome feature.
