Fortunately, this sign is very large but lightweight. So easy to install. The luminous mark is wide and there are many small glowing LEDs on the key. It can attract everyone's attention who pass by my shop and it is energy-saving. No maintenance required. The outdoor light sign comes with a wireless remote control to turn on/off the flashing mode. Long powder cord but it would be ideal if it had a timer. Better quality than I expected. Definitely a great purchase and very happy with this order. Thanks very much! Love it.
