A system for deployment of traction enhancing agents uses an infrared detecting sensor to receive ambient IR from a roadway, whereby the road surface temperature is determined. The determined temperature is supplied to a traction enhancing agent deployment controller, so that the amount and selection of particular agents can be governed based on the particular road surface temperature. Variations are thereby accommodated, so the most appropriate agent or agents in an appropriate combination and density can be applied.

Traction enhancing deployment system

Liquid and air outlet nozzle assemblies are capable of mounting on a vehicle adjacent the headlights and are positioned such that liquid and air jets from the nozzles intersect prior to engaging the headlight to form a spray mixture that cleans the headlight. The nozzle assemblies are associated with a control valve capable of connection in a pressurized air system on the vehicle and in the pressurized washer system for the windshield wipers and also capable of automatically directing liquid from the vehicle washer system and pressurized air on the vehicle to the liquid and air nozzles to form a headlight cleaning function upon manual activation of the pressurized windshield washer system of the vehicle. An embodiment of the nozzle assembly has an extension and retraction piston for extending nozzle openings toward the headlight in operation condition of the assembly.
