Escort radar provides the exact same thing for probably 1/3 the cost! Look at the picture on the left (2 custom LED lights built into the guages). The K40 is about 6-8 years outdated. The link is just a radar/laser DETECTOR.

They also have a unit like above that is a detector and Laser JAMMER....still for less than 1/2 the cost of the K40.

And no, I don't work for/sell, etc. Escort products. I just have had one for almost 5 years now, and not one ticket using it. I used to get almost 2 a year before it.
