Lights and Sirens

I'm exhibiting my company's wares at the Texas Police Chiefs' Association annual conference in the hoity-toity town of The Woodlands (yes, they're tony enough that "The" is part of the town's name). My booth is facing an area where 8 or 10 different police vehicles are parked to show off various vendors different emergency lighting systems. These days, pretty much all new emergency lighting systems are LEDs. They're extremely bright and have a very low current draw, which are both good things for their intended uses. However, facing this field of vehicles with the constant flashing of brilliant red and blue lights has added a massive headache to my sore feet and back. Wah wah wah...
