Headlight Rings

I drive with my lights on in the daytime for a bit of added safety. The hope is that my lights will help make me more visible in case a driver isn't paying attention, has a dirty windshield, etc. However, headlights are very inefficient for this purpose. First, they are incandescent, which uses a lot of energy. Second, they are highly directional. This is useful for seeing objects in your driving path at night, but only makes your vehicle more visible if you are oriented in exactly the right direction.

I propose a ring of white LEDs around each headlight for daytime use. These will have three advantages:

1. They will use much less energy than your headlights.
2. They will be much more visible than your headlight in all directions that aren't directly forward, and visible enough in that direction as well.
3. The shape and color will be reminiscent of headlights, so little extra comprehension time will be required.

#3 was added after I considered flashing colored lights, but thought of someone staring at the pretty flashing thing they've never seen before for far too long until they realize that it means something that the pretty flashing thing is rapidly growing.
