TMS Medical Technologies offers traffic control signs that use ultra bright LEDs to capture the attention of approaching traffic. These signs can be seen from more than a mile away during night and low-visibility conditions, and are ideal for accident scenes, construction areas, DUI stops and seat belt stops. And unlike standard reflective signs, they do not get washed out by backlighting. Measuring 24 inches and 18 inches, these signs are available in flashing STOP or SLOW on each side, and may be handheld or mounted on a telescoping pole with stand. Signs may be battery operated, and the stand and pole may be collapsed to fit in a vehicle trunk for maximum portability. TMS also offers a 12-inch Crossing Guard Configuration that turns on only when lifted and LED wands that are much brighter than traditional bulb-based wands.
