No, unfortunately this will not work with that headlight. That headlight has adaptive/AFS/curve lighting and requires an OEM ballast. This ballast will not fit (mounting holes and connectors are different). **Q: What are the terms of your 6 year warranty for this ballast?** A: Hello! The 6-year warranty covers the ballast under an exchange and excludes water damage due to a leaking headlight (most often in the Cadillac DTS). You may at any time contact us at help@genxenon.com and we'll take care of you :) **Q: Is this the correct ballast for the following headlights? 8E0 941 004 AH is the headlight model number** A: Hello! No. This will not fit that headlight. Your headlight has AFS (curve lighting). Unfortunately there are no aftermarket replacements for your headlight. You need to buy an OEM one. **Q: What do you do if you find green marks in the connection?** A: Hello! That means the headlight housing is leaking and letting in water. Do not install a new ballast until you repair the leak or replace the headlight housing. The leak could be caused by a number of factors. Sometimes it could be the rear access caps but usually it is the lens that has a bad seal to the housing. This would require removing the lens from the housing and re-sealing it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/44524195-replacement-xenon-hid-ballast-for-cadillac-dts-audi-a4-s4](https://www.desertcart.sg/products/44524195-replacement-xenon-hid-ballast-for-cadillac-dts-audi-a4-s4) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-09*
