A modular system of light strips is configured for use on a roadway surface. The light strips are configured to withstand vehicular traffic driving over the light strips. The light strips have a rigid, durable housing protecting a series of LEDs within the housing. LED lenses direct light from the LEDs through the sidewall of the housing at vehicular traffic on the roadway. The channel is filled with a protective material, such as a polymer resin that protects the LEDs and power supply. The modular system includes a power source or can connect to a power grid. The modular system can include a sensor to activate the system and/or to control the light brightness Preferably the light strips connect together or can be substituted for one another to be interchangeable and easily carried, moved, installed and disassembled.
