PARTSWAY HID Headlight Bulbs D3S

Key specifications

If you need a replacement for a factory D3S HID setup, these PARTSWAY bulbs focus on a whiter color and an OEM-style fit. Drivers looking for a bulb that works across different headlight technologies should look elsewhere: this set is specifically for D3S HID assemblies.

The bulbs use a 6000K cool-white color temperature and a blue optical coating intended to reduce yellow tones. The maker lists output of up to 3,800 lumens and a lifespan of up to 3,500 hours, those are stated maximums, not a guarantee of the same result in every vehicle or over every driving pattern. Heat-resistant, anti-UV quartz glass, xenon gas, and premium electrodes are also listed as part of the design.

The size and base are described as a 1:1 match for an original D3S bulb, for use with compatible factory ballasts and housings. The key constraint is the bulb type: it is not compatible with D1S, D8S, halogen, or LED assemblies. Check the label on the existing bulb or the owner’s manual before choosing a replacement.

Who it’s for

This set is aimed at someone replacing bulbs in a vehicle that already came with D3S HID headlights. For example, if one side has begun to look dim or yellow, these bulbs are intended to restore a cooler, whiter appearance while keeping the original bulb format. The maker says they fit compatible factory ballasts and housings without wiring modifications, which may suit a like-for-like replacement better than a conversion kit or a different headlight setup.

A solid pick if your vehicle’s original equipment is confirmed as D3S and you want a matched pair rather than a single bulb. It might not be a great match if you have halogen headlights, an LED assembly, or a different HID bulb type, the listed fit is narrow, and the similar-looking product codes are not interchangeable. Also, the supplied details don’t identify vehicle-specific fitments, so the original bulb label or manual matters more than a broad vehicle description.

What you get

The listing specifies a pack of two D3S HID bulbs, so the purchase is set up for replacing both sides rather than keeping one old bulb paired with a new one. That can be useful when both lamps have aged, though the listing does not provide instructions for a particular vehicle or establish how accessible its headlight housings are. The claimed 1:1 size and base refer to the original D3S format, not a universal fit.

PARTSWAY also states that the set includes a 2-year warranty and product support for compatibility, installation, and use. The advertised service life is up to 3,500 hours, according to the maker. Actual fit still depends on having the matching factory D3S system.

Questions before you buy

Will these work in a halogen headlight? No. The listing specifically excludes halogen assemblies, as well as LED, D1S, and D8S setups. They are intended for vehicles originally equipped with D3S HID bulbs.

Do they require wiring changes? The maker describes them as compatible with factory D3S ballasts and housings and says no wiring modifications are needed. That does not confirm fit for a vehicle with a different bulb type or headlight assembly.

What color light do they produce? They are listed as 6000K cool white, with a blue optical coating designed to reduce yellow tones. The stated output is up to 3,800 lumens.

Final verdict

Choose these if you have verified a factory D3S HID setup and want a two-bulb replacement with a cooler color than a yellow-toned lamp. The format, claimed OEM-style dimensions, and included pair make the intended use clear. Skip them if you cannot confirm D3S compatibility, or if you need bulbs for halogen, LED, D1S, or D8S headlights, the compatibility limitation is the deciding factor here.
