I have purchased many different lights but none are as satisfactory as these.

How’s Your DogTM Blinkers use Light Emitting Diodes (L.E.D.) technology, now considered “the greatest invention in lighting since Edison’s light bulb in 1879″. LEDs are constructed from tiny solid-state chips similar to those used in computers. These chips directly convert electricity to light without the use of a filament or glass bulb. LEDs are rapidly replacing light bulbs in a variety of high reliability applications, including traffic lights, warning signs and emergency exit signs.. more.
