GTMOTO D2S HID Xenon Low-Beam Bulbs for Acura TL TSX 2004–2014 — 6000K Cool White, Direct-Fit D2S-C1

GTMOTO D2S xenon low-beam bulbs are a direct-fit HID upgrade designed to replace factory D2S projector bulbs in 2004–2014 Acura TL and TSX headlight low-beam positions.

These GTMOTO bulbs swap into the OEM D2S-C1 sockets and deliver a cooler, brighter white beam (6000K) compared with many stock 4300K units. Built from laser-cut anti-UV quartz glass with a stainless bracket and ceramic insulating tube, the set of two aims to restore or improve visibility for Acura models equipped with factory bi-xenon projectors. They require compatible AC 85V 35W ballast operation—these are not halogen replacements.

Will these bulbs fit my Acura TL or TSX low-beam headlight?

Yes, if your vehicle uses factory D2S 35W bi-xenon projector bulbs in the low-beam position, GTMOTO D2S-C1 bulbs are made to fit without modifications. They follow OEM D2S-C1 form factor so installation is a plug-and-play replacement in most compatible headlamp housings.

• Compatible models: Acura TL and TSX with factory D2S bi-xenon low beams, 2004–2014 ranges noted.
• Socket type: OEM-standard D2S-C1—no cutting or splicing required.
• Power requirement: AC 85V 35W operation via external ballast.
• Not compatible with halogen sockets like H1/H7/H11/9005 types.

How much brighter and what color will the light be?

These bulbs produce a cooler daylight-white output at about 6000K, visibly whiter than typical 4300K factory xenon bulbs. Brightness is enhanced over many OEM low-beam units, offering clearer contrast and longer perceived reach in the beam pattern.

• Color temperature: approximately 6000K cool white for improved road contrast.
• Perceived brightness: around 1.5× improvement compared to certain baseline D2S units.
• Light quality: crisp, sharp beam suitable for projector-style reflectors.
• Not a halogen replacement—requires HID ballast for proper operation.

How difficult is installation and what should I prepare?

Installation is intentionally simple and typically takes under 10 minutes when your headlamp already uses D2S bulbs. The GTMOTO D2S-C1 bulbs are designed as direct replacements; you will only need to ensure you have a compatible ballast and that wiring matches the AC 85V 35W requirement.

• Installation time: approximately 10 minutes per side with basic access to headlamp.
• Tools: usually none beyond access to the headlamp compartment.
• Pre-check: confirm existing bulb is D2S, not halogen or filament type.
• Do not attempt to use without the correct HID ballast or with halogen housings.

What are the build quality and durability features?

GTMOTO uses laser-cut anti-UV quartz glass for the capsule, stainless metal brackets for secure mounting, and ceramic insulating tubes to handle high temperatures and electrical stress. The materials and construction target consistent performance inside projector housings.

• Quartz glass capsule resists UV degradation for longer optical clarity.
• Stainless brackets provide precise fit and corrosion resistance.
• Ceramic insulation minimizes heat-related failure points.
• Packed as a set of two to refresh both low beams together.

Who is this for: GTMOTO D2S xenon low-beam bulbs are ideal for Acura TL and TSX owners (2004–2014) who have factory D2S bi-xenon projector low beams and want a cooler, brighter daylight-white output without housing modification. Avoid these bulbs if your car uses halogen filament bulbs or if you lack a compatible HID ballast; they are not a halogen retrofit and will not function in incompatible sockets.
