TMS Medical Technologies offers traffic control signs using ultra bright LEDs to spell out the word STOP or SLOW to capture the attention of approaching traffic. Powered via 4 D Cells or AC or DC power, the signs can be seen from over a mile away during night and low-visibility conditions and are ideal for accident scenes, construction areas, DUI stops and seat belt stops. Unable to get washed out by backlighting, Light for Life Signs are available in 24 inch and 18-inch sign configurations flashing STOP or SLOW on each side. These durable signs meet MUTCD Specifications and are constructed using high grade reflective materials and conventional coloring. Able to be hand operated or freestanding, the sign, stand and pole are designed to collapse for easily storage and transport.
