Kustom Signals' pole-mounted radar speed displays feature full-matrix, high-intensity LED displays to get the attention of oncoming drivers as a reminder to slow down. These pole-mounted displays can be directly hard-wired to the electric service or powered by a solar/battery back-up system. Four models are available to meet department's needs and budget. Each offers a 12 or 18-inch display size, appropriate for areas with different speed limits.
