D5S Xenon HID Bulbs for Compact OEM Projector Headlight Systems
This Underground Lighting collection is dedicated exclusively to the D5S bulb, a Xenon HID headlight format engineered as a self-contained HID lighting system. Unlike traditional HID formats such as D1S, D3S, or D4S, the D5S design integrates both the igniter and ballast into the bulb base, eliminating the separate external ballast arrangement used by several earlier HID systems.
The D5S bulb operates on a 42V AC electrical system at 25W nominal power, making it electrically and mechanically incompatible with 35W HID systems. This lower-wattage design is intentional, allowing D5S bulbs to function safely within compact OEM projector or hybrid lens headlamp modules commonly used in late-model sedans and SUVs. The bulb uses a PK32d-7 indexed twist-lock base, which defines housing compatibility and prevents incorrect installation into D1, D3, or D4 sockets.
A defining characteristic of the D5S Xenon HID bulb is its mercury-free construction, ensuring compliance with RoHS environmental standards and modern DOT / ECE lighting regulations. This eco-compliant design is increasingly required in newer vehicles across regulated markets and supports easier disposal and long-term regulatory compatibility.

- 35W output
- 3200 lumens per bulb
- 6000K white color temperature
- 12V circuit specification
- 1-year warranty
For reference, an OEM-spec D5S lamp is typically a 25W design producing around 2000 lumens, with OEM color temperatures commonly around 4300–4500K. Underground Lighting's current D5S pair is specified differently at 35W, 3200 lumens per bulb, and 6000K, giving it a cooler white appearance and higher published output than the standard 25W D5S reference.
D5S bulbs are commonly used in factory HID headlight systems with compact integrated electronics. Applications exist across selected GM, Ford, Jeep, Hyundai/Kia, and other vehicle platforms depending on the headlamp specification. Underground Lighting specifically lists the current D5S product for the 2016–2018 Chevy Silverado 1500 with factory HID headlights.
Because the ballast and igniter form part of the D5S bulb assembly, replacement should use the correct D5S-specific unit and base rather than a D1S, D3S, D4S, or conventional external-ballast HID bulb. Proper seating and base alignment remain important because the headlamp projector controls beam focus and cutoff around the position of the HID arc.
This category supports D5S bulb replacement through Underground Lighting with emphasis on correct D5S fitment, electrical compatibility, color temperature, and projector alignment rather than treating all D-series HID bulbs as interchangeable.
