Totally worth it too. They really improved the distance I can see at night, a lot more like a new car in terms of light output.
Since my commute has me driving before dawn for several months out of the year it’s worth it, tons of deer and other animals about where I’m at now. I’m not going to stop driving my car, but that doesn’t mean I’m not going to try to give myself the best shot at not wrecking it. Seeing further and stopping faster are the best upgrades for that.
