OEM HID Headlight Ballast — Hyundai & Kia Direct Replacement

This is the direct OEM replacement for the Daesung Electrics DHB-D3-LIN headlight control module — as fitted to Hyundai Santa Fe, i30, i40, K900 and Kia Sorento and Sportage from 2013 to 2020.

It restores reliable, flicker-free operation to your factory D3S or D3R HID xenon headlight system. No coding, no rewiring — plug straight in and it works.

The DHB-D3-LIN uses a LIN bus communication system. This means only an exact OEM-spec replacement will work correctly. Our unit matches the original Daesung Electrics Mobis specification exactly.

Seeing "Check Headlight (Low)" on your dash? That is the most common sign of a failed DHB-D3-LIN ballast. A flickering headlight, random shut-off, or a headlight that won't ignite are also typical symptoms.

Important: The DHB-D3-LIN is for D3S and D3R globes only. If your vehicle uses D1S globes, you need the DHB-D1-LIN instead.

1 x Ballast unit. If both headlights are affected, add 2 to your cart.

DHB-D3-LIN vs DHB-D1-LIN — Which One Do You Need?

These two ballasts look identical but are not interchangeable. The difference is the globe type they drive:

  • DHB-D3-LIN (this product): D3S / D3R globes — Santa Fe (2014+), Sorento, Sportage, K900, i30 (2015+), i40 Facelift
  • DHB-D1-LIN: D1S / D1R globes — i30 (2011–2015), i40 (2011–2015), Genesis Coupe, Kia Ceed

Check the globe type and part number printed on the label on top of your original ballast before ordering.


Is It the Ballast or the Globe?

Before replacing the ballast, swap the working globe from the opposite headlight into the non-working side.

If the light still fails with a known-good globe, the ballast is the fault.

If your dash shows "Check Headlight (Low)", this is a LIN communication error; the ballast must be replaced.
