The benefit of LED DRLs(LED Daytime Running Lights)
Daytime running lights (DRLs) are a low-cost method to reduce crashes. They are especially effective in preventing daytime head-on and front-corner collisions by increasing vehicle conspicuity and making it easier to detect approaching vehicles from farther away.

The Daytime Running Light was first mandated, and safety benefits first perceived, in Scandinavian countries where it is frequently and persistently dark during daytime hours. As ambient light levels increase, the potential safety benefit decreases while the DRL intensity required for a safety improvement increases. The safety benefit produced by DRLs in relatively dark Nordic countries is roughly triple the benefit observed in relatively bright Israel and America.

What’s good about DRLs?
1. They are proven to reduce head-on collisions on two lane roads, especially at dawn and dusk. This is what they were designed to do, and if they were implemented just to do this then you wouldn’t see much opposition to them. You often see signs on roads in California proclaiming “Daylight Safety Test Section — Turn on Headlights.” These are the places where DRLs would be useful. Sadly, instead of coming up with a way to use DRLs only when appropriate, certain parties would like them to be on all the time. Why? Money. It’s cheaper to implement a lame system than a well-designed system.
2. They counteract the lack of common sense of dimwitted drivers that fail to turn on their headlights when it’s foggy, rainy, or dark. Of course this is only a positive because these drivers are not doing the proper thing and turning on their headlights AND taillights. If the presence of DRLs causes drivers, who would normally turn on their regular lights in these conditions, to not turn on their regular lights, then this is a negative. A better solution to this problem would be sensors that trigger a warning to the driver to turn on their lights.
3. Some of the cars bought by the worst drivers come with DRLs, i.e. Saturns and Volvos. Thus the presence of a DRL equipped vehicle is a warning to other drivers to be careful.
So it is a good for you to choose DRLs. They are a feature that costs little to add to a vehicle. By intentionally incorrectly extrapolating data from inapplicable studies, companies like General Motors (and others) have created a problem that doesn’t exist, and a solution to fix the non-existent problem. The problem for normal people is that the automaker’s solutions are so poor that they make the problem worse or create a new problem altogether.
They could have done a DRL implementation that was good. The important thing is that they can now advertise that their vehicles include this vital new safety feature. There are enough dumb people in the world to jump on the bandwagon of anything that, on the surface, appears to make driving safer.?? A similar situation exists with the lowering of the alcohol blood level for drunk driving. States are in competition with each other to see who can go lower.
