The "light" is different. Solar power aint cheap. Good panels cost. Good regulators cost, otherwise you can have a high ongoing cost of deep discharge lead acid batteries. Small installations

Anyone care to comment on the feasibility of using solar power to power 12 volt Leds in a house. I bought a red 5 bulb Whelen taillight for a bugout motorcycle I,m almost done with. . It is so damn bright I wish I had bought a smaller 3 bulb one. It uses about half a watt of power. People shade their eyes at night behind me at a stop light. I,m not sure why this wouldn't be the best way

No, you probably can't find a ready made system or standardized components, and probably won't for a very long time, even though we've had the capability to do it for well over a decade. It's not a matter of 12 volts versus 120 volts, but one of corporate greed
