This is a lab tool used to measure the beam pattern of automotive lighting. It’s how you test for DOT compliance, and we can also take a full measurement of the beam pattern to see how much light shines to the road.
Here’s a comparison of the low beam headlight options. This is a top-down view of the road, with the JL Wrangler parked on the left side. Overall, the LED has much more width, and more intensity, though the total distance you can see with these is not significantly different
