A319 Flight Attendant reported concerns over Emergency Exit Light operations on aircraft.

Narrative

Emergency Exit Signs: All illuminated all the time. Wiring issue. Please ensure all emergency lights are off as these are to only be on during an emergency. Additionally; having these lights on all the time disturbs our Customers. Having these turned off would be consistent across the fleet. This is a safety hazard:A. Defeats the purpose of Flight Attendant (FA) turning on emergency lights.B. Passengers get accustomed to emergency exit lights always being on; thus; during an emergency; eyes are not directed toward exits because their eyes have gotten so used to those exit lights always being on; thus increasing time needed to locate an exit and reducing quick evacuation.C. Harsh and bright light always being on is extremely Customer unfriendly as passengers are unable to rest their eyes and relax; most especially on early morning and late night flights.D. Ensuring emergency lights are only on when activated by FA would create necessary consistency with entire fleet.E. No other fleet type has emergency exit lights always on. Please ensure emergency exit lights are off at all times unless activated for consistency.Please audit entire Airbus fleet to ensure emergency exit lighting wiring is correct; that emergency lights are only illuminated when activated by FA pressing Emergency Lights button on FA panel; and extinguished at all other times. Please make the default setting for emergency exit lights to be off for all Airbus aircraft. Please create a maintenance message to address this so these can be fixed as soon as possible. Emergency lights should only be on when FAs or Pilots activate these in emergency situations; not constantly; please help. Thanks!
