It great for visibility for both me and traffic, but aimed well so that it doesn't blind other road users. California (Bay Area) traffic can be downright treacherous even during Covid, this helps keep me stay visible in a sea of lights.
I was actually surprised how much light the Weisers put out in DRL mode, it's not really usable light, but it does make me more visible. I have the in the rear too, but the 2nd mode is brake light instead of DRL. My Aux lights are only at 10% during daylight hours and 40% at night. They don't go to 100% without using the high beams.
