Previous page Next page SOLAR G40 50FT " data-position="triggerHorizontal"> Why Does My Solar String Light Not Work? It will turn on automatically in dark and turn off at dawn, if you want to turn it on at daytime, please put the solar panel in dark or use something to cover it If one edison bulb goes out, will the rest stay lit? These light strands are connected in parallel, so one bulb broke or burnt wont affect the rest bulb. Are the festoon solar lights outdoor waterproof? Yes, these products are IP65 waterproof. You can use the string lights under normal weather conditions. Are the bulbs glass? No, our G40 bulbs are made from high temperature resistant plastic and will not shatter if dropped from 15m and will not form dangerous glass shards like glass does.
