GTR Ultra 3.0 5202 / 2504 white LED bulb pair
The GTR Lighting Ultra 3.0 5202/2504 pair provides 5750K white output with custom TST 7045 emitters. GTR.LED807 is the exact part number for this two-bulb package, intended to be selected against the requirements of your existing lamp.
GTR uses Thermal Separation Technology to manage heat around the emitters and pots the electronics for protection. Compare the compact bulb with your available housing space, including the room needed to refit a dust cover. Physical clearance still depends on the installation.

Before installation
Check the bulb marking, connector, retaining mechanism and rear clearance on the lamp you actually have. An aftermarket housing may use a different bulb from the original vehicle equipment. Optional anti-flicker harnesses are sold separately; confirm whether your lamp circuit needs one.
Are an anti-flicker harness and Allen key included?
The current supplier package list for GTR.LED807 names two bulbs. Its anti-flicker harness is an optional purchase, and an Allen key is not listed in that package block. Do not assume accessories shown with another Ultra 3.0 model are included here.
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.
