Comatra Blue LED Lights
For best results the lights should be mounted on the wing booms close to the pivot shining out to the end of the boom. They need to be behind the nozzles so that the light will illuminate the nozzle pattern. Make mounting brackets as needed. They only draw 1.5 amp each so you could connect them to the light circuit or use a separate power supply. See the pictures for an example of where to mount the lights.
