Maybe you just came to this page and wonder what self-luminous means. These signs do not require any electricity, no matter what lifespan you chose. You will not find a single circuit, battery or wire anywhere inside these self powered exit signs.

This is because electrical components eventually corrode and degrade while batteries lose effectiveness over the years. In most cases, it is more expensive to replace these components than to just buy a new sign.
