OL4 Solar Safety Light

Solar Warning Light for Tough Industrial Locations

The OL4 is a light-weight, high-performance solar safety light with superior energy management. Designed for tough industrial locations such as mines and constructions zones, the OL4 solar warning light is ideal for marking ground hazards, fences, barricades and other construction hazards on site.



  • Self-contained in a durable, rugged enclosure
  • No specialized work crews required: simple to install and relocate
  • User-friendly design: onboard interface offers easy configuration and programming
  • Low maintenance: replaceable battery pack with a 5-year life expectancy
  • Tested at the toughest industrial standards
  • Light environmental footprint with natural solar charging, recyclable batteries and RoHS-compliant design


OL4 Models & Options


Color Output: The OL4 is available in various color configurations depending on your application. Check the specifications to see the intensity settings for each color option. Peak intensity is dependent on your location and selected flash pattern.


OL4 with ON/OFF Switch: The solar safety light with an ON/OFF switch option lets you easily turn the light on and off when needed. When the switch is in the ON position, the light will charge during the day and turn on at night. When the switch is in the OFF position, the light will still charge but won’t turn on at night.


OL4 without ON/OFF Switch: The solar warning light without an ON/OFF switch is preprogrammed to turn on at night. Simply mount the light where you need it, and it will automatically charge during the day and turn on at nightfall.


GPS Control: Ideal for tower and crane applications or projects where you need the lights to flash at the same time, the OL4 GPS control option syncs multiple equipped lights to flash in unison.
