1157: X-VF LED Bulbs (Switchback)

The Morimoto X-VF 1157 LED Bulbs represent a major leap forward in LED bulb technology. After refining their original XB LED platform, Morimoto developed the X-VF (Virtual Filament) series to deliver superior optical performance, improved reliability, and a more factory-correct light distribution. The result is an LED bulb that not only looks great but also performs exceptionally well in real-world driving conditions.

Designed for use in turn signals, brake lights, tail lights, and marker lights, the X-VF bulbs provide instant illumination, long service life, and outstanding brightness while maintaining an OEM-style light pattern.

Virtual Filament Technology

Unlike conventional LED bulbs that concentrate light in only a few directions, Morimoto's Virtual Filament design utilizes precision optics to distribute light evenly throughout the entire reflector housing. This maximizes the effectiveness of your factory lens and reflector, creating a brighter, more uniform output with excellent visibility from every angle.

Improved Version 2 Design

The second-generation X-VF bulbs were engineered with one goal in mind: performance over gimmicks.

Key improvements include:

• Optimized optics for superior 360° light distribution
• Increased side and rear-facing illumination
• Better reflector utilization for greater visible brightness
• Cleaner, more OEM-like appearance

Instead of simply producing more raw light, the X-VF bulbs focus on placing light exactly where it's needed.

Fade-On Switchback Function

Available on the Switchback White/Amber models, Morimoto's unique fade-on driver gradually restores the white running light after the amber turn signal turns off. This smooth transition creates a refined, premium appearance rarely found on aftermarket LED bulbs.

Universal Compatibility

Morimoto eliminated the common compatibility headaches associated with earlier LED bulbs.

Features include:

• Universal CK and Non-CK compatibility
• Wide "Fat Boy" electrical contacts for improved connection
• Reduced risk of bent or damaged terminals
• Easier installation across a wider range of vehicles

CANBUS Friendly

The X-VF bulbs are designed to work with most modern CANBUS-equipped vehicles without triggering bulb-out warnings.

Some applications may still require additional resistance. When needed, Morimoto HD Load Resistors can be installed to eliminate hyperflash or warning messages.

Advanced Thermal Protection

Long-term reliability starts with proper heat management.

Instead of relying on dozens of small LEDs that generate excessive heat, the X-VF utilizes six high-performance CREE LEDs mounted within a precision optical assembly. A ribbed aluminum heat sink efficiently dissipates heat, while an integrated thermal protection circuit automatically reduces output if temperatures become excessive, helping maximize bulb lifespan.

Vehicle Compatibility Note

Due to factory wiring characteristics, the Switchback version is not recommended for:

• Ford vehicles
• Toyota Tacoma
• Toyota Tundra

Standard single-color versions remain suitable for most applications.
