GTR Ultra 3.0 9005/HB3 LED bulb pair
The GTR Lighting Ultra 3.0 GTR.LED803 is a 5750K white pair offered for the 9005/HB3 and H10/9145 family. It combines a compact body with GTR’s custom TST 7045 emitters, giving you one clearly identified model to compare across those listed bases.
Prefer yellow output? Compare the separate 3000K GTR Ultra 3.0 9005/HB3 yellow pair and confirm your housing requirements.
GTR’s Thermal Separation Technology design manages heat around the emitters, while the electronics are potted for protection. The compact format is worth comparing with the space behind your lamp, especially where a dust cover limits room. It is a design feature, not a guarantee of clearance in every housing.

Plan the installation
Compare the existing bulb marking, connector, retaining hardware and rear clearance with this model. If the housing has been changed, use its requirements rather than assuming the original vehicle lookup still applies. Anti-flicker harnesses are optional accessories, sold separately; confirm whether your equipment needs one before ordering.
A common question
Does this 9005/HB3 model also cover H10 and 9145?
The supplier lists the selected GTR.LED803 pair as 9005/9145/H10, with HB3 in the product identity. Match the actual lamp and lighting function; this is not a promise that every vehicle using one of those bases will accept the installation.
Intended use
These bulbs are not compliant for public-road headlight use in the United States. Fog-light and other applications must meet applicable local requirements. Verify the intended application and local rules before installation.
