1156: GTR i-LED Ultra Turn Signal Bulbs

The GTR Lighting Ultra i-LED was designed with one goal in mind: deliver superior lighting performance through intelligent engineering, not exaggerated lumen claims. Every aspect of the Ultra i-LED has been carefully developed to maximize usable light output, improve reliability, and provide an OEM-quality appearance that stands above conventional LED replacement bulbs.

Whether you're upgrading your turn signals, brake lights, tail lights, or daytime running lights, the Ultra i-LED offers exceptional performance without compromise.

Ultra Optics for Maximum Visibility

Unlike traditional LED bulbs that simply emit light in every direction, the Ultra i-LED features an advanced optical system engineered to work with your vehicle's factory reflector.

Its precision-designed optics project light forward for excellent close-range visibility while redirecting a large portion of the output back into the reflector housing. This creates a brighter, more evenly distributed light pattern that dramatically improves visibility from a distance, where it matters most.

Intelligent i-Driver Electronics

Inside every Ultra i-LED is GTR's advanced i-Driver system.

Upon activation, the bulb delivers a brief burst of maximum brightness before automatically reducing output to an optimized operating level. This intelligent power management provides exceptional initial intensity while reducing heat buildup and ensuring long-term reliability.

High Output Without the Hassle

Despite producing impressive light output, the Ultra i-LED draws power similar to many factory incandescent bulbs. This allows resistor-free operation in many applications, simplifying installation and reducing unnecessary wiring.

For turn signal applications where hyperflash may occur, optional plug-and-play anti-hyperflash modules are recommended for flawless performance.

Premium Looks Day and Night

The Ultra i-LED doesn't just improve your lighting—it enhances the appearance of your vehicle.

Instead of exposing LED chips like many aftermarket bulbs, the Ultra i-LED hides its emitters behind crystal-clear optical lenses housed in a precision-machined anodized aluminum body. The result is a clean, high-end appearance that looks just as impressive when the lights are off as when they're illuminated.
