xB headlights are the front lighting assemblies used on the Scion xB, a compact hatchback produced by Scion/Toyota. In simple terms, they are the lights that illuminate the road ahead and make the vehicle visible to others at night.
These headlights vary between the model’s generations and trims. The Scion xB was offered in two main design generations, with OEM headlight shapes changing between them. Today, owners can stick with factory units or pursue a range of aftermarket upgrades, from cosmetic changes to performance-oriented projects. Understanding what you’re buying requires matching the headlight housing to your vehicle year and generation and knowing whether you want halogen, projector, HID, or LED options.
Origin, purpose, and what they include
Headlights on the xB serve multiple roles: providing low and high beam illumination, housing the daytime running or parking lights, and sometimes integrating turn signals. The exact configuration—such as reflector-based halogen units or projector-style assemblies—depends on the generation and trim level. Upgrading can improve beam pattern, brightness, and aesthetics, but may require electrical work or alignment adjustments.
Generations and designs
First generation (roughly 2004–2006)
The original Scion xB featured a boxy, straightforward headlight design that integrated into the front fascia with standard halogen reflector optics common to many compact cars of the era. These headlights were typically easier to replace with OEM units and certain aftermarket options focused on cosmetic updates rather than major performance changes.
Second generation (roughly 2007–2014/2015)
The second-generation xB brought a changed silhouette and headlight shape, generally larger and more rounded than the first version. Depending on the model year and trim, you could encounter different housing styles, including assemblies that accommodate projector-style elements or updated lens treatments. As with the first generation, there are both stock and aftermarket options, ranging from simple replacements to more feature-rich upgrades.
Upgrade and replacement options
When shopping for xB headlights, you’ll encounter a range of options from OEM replacements to aftermarket styling and performance upgrades. Each option has implications for fitment, wiring, beam pattern, and compliance with local regulations.
- OEM replacement headlights (stock halogen reflector or projector-based units, matching your year and generation)
- Aftermarket projector headlights (often with improved cutoff and beam pattern)
- LED or HID upgrade kits (may require wiring harnesses, ballasts, and proper ballast compatibility)
- Halo or accent LED rings for cosmetic flair
- Smoked, clear, or color-tinted lens housings (cosmetic options)
- Retrofit kits that combine projector lenses, cutoff shields, and upgraded bulbs
In short, these options span from straightforward replacement parts to more involved upgrades that can change the look and performance of the xB’s front lighting. Always verify compatibility with your specific year and generation, and consider professional installation for complex upgrades.
How to replace or adjust headlight aim
If you plan to replace the headlight assembly or aim the headlights after an upgrade, follow these general steps. Always consult your vehicle’s service manual for model-specific instructions.
- Park on a level surface about 25 feet (7–8 meters) from a wall; ensure the car is on level ground with the same tire pressure as when driving.
- Disconnect the negative battery terminal to protect electrical components.
- Remove the old headlight mounting screws/bolts and detach the wiring harness from the back of the assembly.
- Install the new headlight unit, reconnect the wiring, and secure the mounting hardware.
- Reconnect the battery, turn on the headlights, and check alignment against the wall. Use the adjustment screws on the back/top/side of the housing to fine-tune the beam pattern.
Following these steps helps ensure the new or upgraded headlights fit correctly and illuminate the road as intended. If you’re unsure about wiring or aiming, seek professional installation or alignment services.
Summary
xB headlights are the front lighting assemblies for Scion xB models, with designs that vary by generation. They can be replaced with OEM units or upgraded to projector, HID, or LED configurations, along with cosmetic options like tinted lenses or halo accents. When upgrading, verify generation compatibility and be prepared to address wiring and alignment to maintain safe, compliant illumination.
