One of the many, many things I love about my smartie are her peepers. The headlights, perfectly adjusted, project a broad, exactly straight band of sight; a ruler-line defines its ceiling...no glare to the oncoming traffic.
The frog lights add a slightly brighter, noticeably broader band, illuminating the right and left banks of the road like a cat's eyes in the dark.
In actual fog, the low, low frog lights slip under the murkey greyness, without bouncing back at you. Always remembering that the wildlife cross our hiways and byways, I prefer to throttle way down in poor visibility.
My teensy, tiny criticism is that the headlights must be on for the frog lights to work. And truth be told, I drive with my lights on always, so it's really no criticism at all.
Another testament to the superior design and engineering of the fabulous smartie.
