TrafficX Custom is one of those newer traffic script mods for GTA 5 that doesn't try to completely reinvent the wheel but still manages to make driving around Los Santos feel different. Instead of messing with traffic paths or cranking vehicle density to the point where your FPS suffers, it focuses on the cars already on the road and gives them more personality. After years of seeing the same vehicle variations at every intersection, even small visual changes can make the city feel refreshed—especially once nighttime hits and the lighting starts to pop GTA 5 Modded Accounts.
The main idea behind the mod is pretty straightforward. It randomly customizes NPC vehicles near you with cosmetic upgrades, so traffic no longer looks factory-stock. You'll start noticing altered bumpers, spoilers, skirts, hoods, fenders, exhausts, grilles, and other parts showing up in everyday traffic. Some cars lean tuner, others feel more luxury-styled, but it never goes so far that it looks out of place. Window tints are added in a natural way, and wheel swaps are kept "traffic-safe," meaning you won't see ridiculous rim sizes or clipping issues breaking immersion. Importantly, it only affects NPC cars—your personal builds stay untouched.
Where the mod really separates itself is the neon system. NPC vehicles can spawn with underglow in several different styles: static colors, RGB cycling, basic blinking, color-based flashing, or mixed setups where each car behaves differently. You can decide whether neon shows up only at night or all the time, depending on whether you want realism or a more arcade street-racing vibe. Cruising through downtown after dark with multiple neon modes active genuinely changes the atmosphere, making Los Santos feel closer to a modern nightlife scene than the base game ever did.
Even with all the extra visuals, performance stays front and center. TrafficX Custom uses distance-based processing, so vehicles close to you get the full treatment—neon animation, logic checks, and other effects—while cars farther away are simplified to save resources. Distant neon can even be disabled entirely. This makes it very different from heavy traffic or density mods that brute-force more vehicles into the world and end up dragging performance down. You still get visual variety, but without turning your game into a slideshow.
There's also a smaller feature that ends up making a noticeable difference over time: light crashproofing for NPCs while they're inside vehicles. It doesn't make them invincible—it just reduces those annoying situations where minor fender-benders cause drivers to die instantly, panic, or create massive pileups that attract police. Combat damage and serious crashes still behave normally. It simply smooths out everyday traffic behavior so free-roam driving feels less chaotic for the wrong reasons.
Setup is flexible. You can control everything through an in-game menu or an .ini file. By default, the menu opens with F5, and from there you can toggle the script, adjust how often cars get customized, change neon probability and modes, set neon to night-only or always on, and manage crashproof settings. Once you open the menu, a config file is generated in your scripts folder, which makes it easy to fine-tune things outside the game—handy if you're building a larger mod setup GTA 5 Money On Xbox One.
For anyone who wants Los Santos to feel a bit more current without sacrificing performance, it's an easy recommendation. Day-to-day driving, police chases, and late-night cruises all benefit from the added variety. Cars stop looking cloned, neon adds nightlife energy when you want it, and the lightweight design keeps everything running smoothly. It's a simple concept, but in practice it does a lot to give familiar streets a new mood.
