The previous arrival reported a deflection in the runway 7L localizer when intercepting the glideslope. Aircraft X was inbound on the runway 7L ILS while DAB was below basic VFR minima. I advised Aircraft X of the previous arrival's report and watched him closely as he was inbound. I could not see him out the window because of poor visibility but saw that he appeared low on the TDW [Tower Display Workstation]. The LA [Low Altitude Alert] did not alarm but I was about to issue one anyway because of his proximity from the FAF [Final Approach Fix] and the terrain. Before I keyed the mic I remembered that our tower video map has been wrong for the past few years. The runway 7L ILS approached changed FAFs and their locations. TOMOK was the old fix that is still displayed on the map but the new fix FOLIG is in a different place. If I had issued a LA based on the incorrect fix despite the aircraft's altitude being fine; it could have resulted in pilot disorientation in IMC.This map; along with a few other TRACON maps; need [to be] updated. I have talked to our OM [Operations Manager] about the issue several times in the past and nothing seems to get done. Two TRACON maps show incorrect boundary lines with adjacent facilities which could result in ODs [Operational Deviations]. The tower map with the incorrect FAF is the more important of the maps to get corrected because it can affect aircraft at low altitudes in poor weather conditions.
