Highway Legends Underglow: Custom Shop Guide

Highway Legends underglow is a vehicle cosmetic lighting upgrade applied in the custom shop. Drivers install underglow beneath their chassis to illuminate the asphalt with custom colors and animated light effects.

How Do You Equip Underglow in Highway Legends?

Underglow installation takes place directly inside the custom garage facility located off the main highway. After purchasing a vehicle from the dealership or spawning an existing ride from your garage, drive to the custom shop entrance to access vehicle modification menus.

1. Drive your car into the custom shop bay from the dealership lot.
2. Select the paint or customization menu on the interface screen.
3. Open the underglow subcategory to view the lighting palette.
4. Select your preferred color, such as red, green, blue, or white.
5. Click apply to save the neon light color to the vehicle chassis.
6. Exit the custom shop to test the ground illumination on the dark highway.

Adjusting cosmetic elements allows you to match neon tones with body finishes, calipers, and rims. While setting up cosmetic touches, pairing lighting choices with your vehicle suspension settings creates a unified street build for night driving.

Sometimes codes are released, and if you type Highway legends code on Google or other search sites, active codes will usually appear.

Which Underglow Options Require Game Passes?

Standard neon colors are available without premium currencies in the custom menu, while animated lighting patterns require the Extra Customization gamepass. According to the official Roblox data, the Extra Customization pass costs 299 Robux and adds several distinct styling features to the garage workshop.

The pass overview on the Highway Legends Wiki specifies the exact benefits included with the upgrade:

Players who maintain a free garage can still use primary solid colors across their vehicles. Those purchasing premium passes obtain dynamic light displays such as pulsing party effects and multi-toned fire visuals beneath the car body.

Custom Shop Lighting and Visual Combinations

Neon lighting is a bottom-mounted visual modification that casts colored light onto the road surface. Pairing ground illumination with vehicle body materials like metallic, matte, chrome, or carbon fiber changes how the lights reflect off nearby street surfaces.

When customizing dark vehicle bodies like midnight blue or black, choosing high-contrast white or red underglow keeps the car outline clearly defined in low-light highway zones. Drivers who prefer brightly painted bodies, such as yellow or cream, can install deeper primary undertones to balance the overall vehicle appearance.

Funding cosmetic adjustments and mechanical performance tuning requires building up your in-game cash balance. Drivers can accumulate currency through playtime rewards, completing daily quest objectives, and mastering how to play by cutting through highway traffic at speed. Reviewing available gamepasses provides access to specialized tuning parts and custom cosmetic options across every car class.
