Blank Out Signs

SES America BOS or Blank Out Sign from the line Mobility

Customizable LED Blank Out Signs with fixed, limited messages for specific and simple functions.


Blank Out Signs display only a limited number of messages, but are much cheaper, consume much less energy and are very easy to operate.

Blank Out Signs can simply be connected to an ON/OFF switch, though SESA also offers an intelligent interface in case a serial communication is needed.

While we offer a range of MUCD compliant symbols, we can also easily produce almost any symbol or text message upon request for our Blank Out Signs. You define the size, dimensions, and colors of the text or symbols on the Blank Out Signs.

Wrong Way Sign

  • The Wrong Way Sign is a type of Blank Out Sign, designed as per MUTCD recommendations.
  • The text on the Blank Out Sign is activated by a simple dry contact connection.
  • The text is white on the Blank Out Signs, with 30 degrees cone of vision double stroke characters (each stroke is separately controlled).
  • There are several available settings on the Blank Out Sign :
    • Double stroke steady
    • Double stroke flashing
    • Single stroke steady
    • Single stroke flashing
    • Blank Out Signs alternate between single and double stroke
  • Blank Out Signs can be powered by solar panels.
  • This Blank Out Sign product is unique to SESA!


  • Any MUTCD symbols can be used on our Blank Out Signs , ex: no left turn, no right turn, no entry, etc.
  • Blank Out Signs can be easily connected to sensors such as flood detectors or wind warning systems, with the message triggering during defined conditions.

Blank Out Sign Production:

  • For standard MUTCD symbols: Blank Out Sign will be manufactured upon receiving purchase order.
  • For non-standard Blank Out Sign messages: SESA will propose a quote based on the message definition and Blank Out Sign dimensions.
  • IMPORTANT: In addition to selling Blank Out Signs to end-users, we also offer them to distributors, weather stations, and other manufacturers. Please contact us for more information on Blank Out Signs.

Tech Details

  • We do not use PCBs in our Blank Out Signs. LEDs are directly inserted in a dedicated and specifically designed guide.
  • There is no front face polycarbonate on our Blank Out Signs that can produce bad glare effect and reduce visibility.
  • Housing on our Blank Out Signs  is light and simple. Access to components can be done through two access doors, one in the front and an optional rear door. No additional cabinet needed.
  • Installing and mounting our Blank Out Sign  is easy with the standard “traffic signal hub” (like our Smart LCS) or with rear mounting devices.
  • Blank Out Signs are equipped with a light sensor (to adjust brightness level to ambient light conditions) and with fault detection (if LED is faulty, an alarm contact is activated).
