📋 About This Mod
The McCarran Field sign is scripted to be lit between 8 PM and 8 PM at night, this little mod changes NVMcCarranSignActivatorScript to allow the sign to be lit between 8 PM and 8 AM.
The Independent Fallout Wiki's recent tweet about this sign noted that the schedule is only 3 hours long.
This untested mod hopes to adjust the sign's on time to be all night long.
Script update shown below

This bug fix mod corrects the McCarran Field sign's lighting schedule in Fallout: New Vegas. Originally scripted to be lit from 8 PM to 8 PM (effectively always on), the mod adjusts the script to light the sign only between 8 PM and 8 AM, restoring intended nighttime-only illumination. A simple, targeted fix for players who want accurate signage.
