Solar Lighting Needed for Highway Sign
We live in the country, and it would cost thousands for the electric company to bring power to light our highway sign. The sign is two 8'x8' signs shaped in a "V" so both directions of traffic can see the sign. I have tried garden solar lights, but they are not bright enough on the ground shining up. I've tried connecting garden/walkway solar lights to the top of the sign (4 of them on each sign), but they are rather weak, and the battery is not big enough. Can anyone come up with larger LED lights and perhaps how to daisy chain the smaller batteries together. Actually I've thought of just getting a larger battery, controller, etc. But I would still need help designing/finding LED lights that would work.
