They are also the best outdoor/indoor sign for withstanding torrential hurricanes and snow storms. The SL-MA does not need electricity at all and uses tritium, a naturally luminous gas that stays charged up to 20 years! In that time you will never have to replace the sign or perform time-consuming operability tests. Massachusetts self luminous exit signs JUST WORK!
