Changeable Message Signs

1.1 The new generation of POLIFORCE's Changeable Message Signs is TRANSFIX™750, with Stealth Screen™. It displays texts and graphical images on a transparent LED screen that is mounted on a patrol vehicle's rear deck/window area. The messages are to visually communicate with drivers of approaching vehicles about road and/or area conditions, without blocking the rear view mirror.


There are currently more than 360 words and 10 graphics to warn and advise the approaching motorists. Words can be combined to create more options to display. Additional messages can be added to the list, including in a second language to make the display of messages bilingual.

Safety messages, such as DON'T DRINK & DRIVE, BUCKLE UP, etc., can be constantly shown. Selection of desired messages is via the touch screen of a tablet, or the vehicle's computer. Voice activation is an option.


Display of messages are done steady, flashing, and in reverse image.


The LED board displays all functions of red, blue, and amber of a vehicle's warning lights.


This model was introduced at the 1993 NSA and IACP exhibits. The CMS-V™ models of the TRANSFIX™ electronic changeable message signs are designed to be attached to the sun visor of a vehicle. Two-word messages such as POLICE/STOP or SHERIFF/STOP can be displayed in mirror image to inform what is expected of the driver in front. Messages can be displayed individually and in alternating patterns, each in steady or flashing modes. Single and double-stroke lettering are available in red. Bi-color models are in red and blue. The Wig-Wag model flashes red and blue lights in various patterns. The CMS-V™ models are ideal for unmarked vehicles. Fully programmable models will soon be available.
