Hella D3S 4300K HID Xenon Headlight Bulb, 35W
Hella D3S 4300K HID Xenon Headlight Bulb, 35W — Product description
The Hella D3S is a factory-grade xenon HID bulb built to drop straight into vehicles that came with D3S projector headlights. It runs at 35 watts and a 4300K color temperature, so you get that clean, neutral-white factory beam without the heavy blue tint. One bulb per box, PK32d-5 base, ready to install.
If your car left the factory with xenon HID headlights, odds are good it's running a D3S bulb. That's the standard for most late-model projector-style HID systems, and it's exactly what this Hella bulb replaces. When one side starts to dim, flicker, or shift color, you don't need a whole new headlight assembly. You just need the right bulb. This is it.
The D3S format runs at 35 watts off a 42-volt ballast, and it works with 12 to 24 volt electrical systems through that ballast. The 4300K color temperature is the important number here. It's a neutral white with just a hint of warmth, which is the color most factory HID systems were designed around. You get maximum usable light on the road without the heavy blue cast that washes out contrast in rain and fog. If you want your headlights to look and perform the way they did the day the car rolled off the line, 4300K is the number you're after.
Output lands around 3200 lumens, which is a big step up from any halogen bulb and puts a bright, wide pool of light in front of you. HID light also holds its intensity better over its life than halogen, so you're not slowly going blind over the last few months before a bulb dies. The tradeoff is that HID needs a ballast to strike and regulate the arc, which your vehicle already has if it came with D3S from the factory.
Here's a question we get a lot. Why 4300K and not something higher and bluer? Higher color temperatures look flashy in a parking lot, but they actually put out less usable light on the road and scatter more in bad weather. 4300K sits right in the sweet spot where the human eye picks up the most detail. It's the color the factory engineers chose for a reason, and it's what keeps your night driving sharp and low-fatigue.
Installation is straightforward on most vehicles. Kill the power, pull the old bulb, and seat the new one by its PK32d-5 base. Two rules matter. First, never touch the glass with bare fingers. The oil from your skin creates a hot spot that can shorten the bulb's life or crack the envelope. Handle it by the base, and wipe it down with alcohol if you do touch it. Second, let the ballast do its job. Don't force power to the bulb directly. It's designed to run through the factory igniter and ballast, and that's what keeps the arc stable.
One thing worth knowing. HID bulbs shift color as they age, and they don't all age at the same rate. If one side has gone dim or pink, the other side usually isn't far behind. A lot of installers replace both bulbs at once so the two headlights match. This listing is for a single bulb, so grab two if you want a matched pair. Your call, but a mismatched set is easy to spot at night.
A quick word on fitment. D3S is not interchangeable with D1S, D2S, or D4S bulbs even though they look similar. The base keying and ballast requirements are different, and forcing the wrong type will either not seat or won't fire correctly. Check your existing bulb or your owner's manual and confirm it calls for D3S before you order. If it does, this Hella bulb is a direct match.
This is a genuine Hella bulb, not a bargain-bin knockoff, and Hella has been building vehicle lighting for a long time. If you've got a vehicle with factory D3S xenon headlights and you want a clean, correct replacement that fits and lights the way the engineers intended, this is a safe pick. It won't turn a halogen car into an HID car on its own, that takes the full projector and ballast hardware, but for a true D3S replacement it drops right in.

Frequently asked questions
What is a D3S bulb?
D3S is one of the standard xenon HID bulb formats used in factory projector headlights on many late-model vehicles. If your car came with HID headlights from the factory, there's a good chance it uses D3S. This Hella bulb is a direct replacement for that format.
Does this bulb come with a ballast?
No. This is the bulb only. It's designed to run on the D3S igniter and ballast your vehicle already has if it came with factory HID headlights. You don't need to add anything else for a straight replacement.
What does 4300K look like?
4300K is a neutral white with a slight warm edge. It's the color most factory HID systems were built around because it puts the most usable light on the road. You won't get the heavy blue tint of higher color temperatures, and that's a good thing for real-world night driving.
Is this a plug-and-play replacement?
Yes, on any vehicle that came from the factory with D3S xenon headlights. Pull the old bulb, seat the new one by its PK32d-5 base, and you're done. It runs on your existing ballast with no extra wiring.
Do I need to replace both bulbs at once?
This listing is for a single bulb. HID bulbs shift color and dim as they age, and if one side has gone, the other usually isn't far behind. Most installers swap both at the same time so the two headlights match. If you want a matched pair, order two.
What base does this bulb use?
It uses the PK32d-5 base, which is the standard mount for D3S bulbs. It keys into the factory housing so there's no guesswork on orientation.
What are common problems with D3S bulbs?
The usual ones are age-related. Bulbs dim, flicker, or shift toward pink or purple as they wear out. Touching the glass with bare fingers during install can create a hot spot that shortens life, so always handle the bulb by its base.
Is 35W or 55W better for a D3S?
35 watts is the correct factory specification for D3S. That's what the bulb, ballast, and housing were engineered for. Over-driving a D3S system to 55 watts runs hotter and can shorten the life of the bulb and the ballast, so stick with 35W.
Can I put this in a car with halogen headlights?
No. A D3S bulb needs the ballast, igniter, and projector housing that come with a factory HID system. Dropping it into a halogen setup won't work and isn't safe. This is a replacement for vehicles that already run D3S.
Is D3S the same as D1S, D2S, or D4S?
No. They look similar but they're not interchangeable. The base keying and ballast requirements differ. Confirm your vehicle calls for D3S before ordering, then this bulb is a direct match.
