How far away will passing traffic be to read your sign? How will they be travelling (walking, vehicles)? This will help determine the ‘pitch’ of the LED sign that is chosen to maximise visibility but retain cost-effectiveness.
Consider a maintenance contract on your LED signage to ensure that your LED message board keeps working for you, 24/7. Also, ensure that you undertake regular maintenance of your power source to maintain visibility.
Do you need your message to be mobile? Consider mounting your LED message board onto a trailer so that it can be seen around town. Talk to Refmac about this option
