All the charm of vintage victorian carriage lantern fairy lights from the past, but with the safety, economy, and features of todays modern leds. They can be used indoors or outdoors, and there are several multi action modes to select from, including static. For added convenience, they have an optional timer function that allows you to program them to turn on for the same 8 hours every day and turn off for the remaining 16 hours. It will keep repeating this cycle, even remembering the flash setting you choose. Perfect for simply setting and forgetting! The original lights from the 60's are still desirable for their retro kitsch appeal, but they came with their problems, one bulb blew they all blew, they got hot, weren't low energy, and they didn't have fancy features like built in timers the little carriage lanterns are black and gold and are 2.5cm long with a 2.6cm diameter, and the full lit length is 4.9m with an additional 5 metres of cable from the transformer to the start of the lights.
