I need to run some wire from the battery to the lights mounted on the front and rear of my e-bike. In a previous thread, 18 gauge was recommended as an acceptable gauge for a 24v low wattage (<25w) load.
I would like to use speaker wire, if it will work because it runs in wire pairs. However, I am not sure of how well it will hold up to exposure to moisture, cold and sunlight. Any advice?
