The Pro Vision Lighting™ OEM HID Headlight Ballast is a direct factory replacement for the Daesung Electrics DHB-D1-LIN headlight control module, as fitted to Hyundai i30, i40, Genesis Coupe, and Kia Ceed vehicles from 2011 to 2016. This unit is engineered to restore reliable, flicker-free operation to your factory D1S or D1R HID xenon headlight system.
The DHB-D1-LIN ballast communicates with the vehicle's factory LIN bus (Local Interconnect Network), which means it must be replaced with an exact OEM-specification unit to ensure correct communication with the headlight system and avoid dashboard warning messages. Our replacement unit is built to the same electrical specification as the original Daesung Electrics Mobis unit, ensuring seamless plug-and-play installation with no coding or rewiring required.
Common fault codes associated with a failed DHB-D1-LIN ballast include B2206 (Right ballast LIN communication error) and B2205 (Left ballast LIN communication error). If your Hyundai or Kia is displaying a "Check Headlight (Low)" warning or one headlight is flickering, shutting off randomly, or failing to ignite, this ballast is the most likely cause.
Note: Quantity of 1 = 1 x Ballast unit. If both headlights are affected, please add 2 to your cart.
This ballast directly replaces the following OEM and manufacturer part numbers:
Daesung Electrics / Mobis: DHB-D1-LIN, DHBD1LIN, DHB-D1
Hyundai / Kia OEM: 3Z921-01700, 3Z92101700
Alternative OEM Numbers: 92190-3Z200, A2921-08100, A292108100
E-Mark Approval: 10R-036053, 10R-0413266
This HID ballast is confirmed compatible with the following Hyundai and Kia models. Always verify by matching the part number on your original unit before ordering.
Hyundai i30: 2011 – 2015 (Hatchback, all engine variants with factory HID)
Hyundai i40: 2011 – 2015 (Sedan / Saloon and Estate / Wagon, Pre-Facelift)
Hyundai Genesis Coupe: 2012 – 2016
Kia Ceed / Cee'D: 2012 – 2016 (JD generation)
Kia Cerato: 2012 onwards (where factory HID fitted)
Please note: This list may not be exhaustive. If your vehicle is not listed but your original ballast carries one of the part numbers above, this unit is the correct replacement. If in doubt, photograph your original ballast label and email it to us at [email protected] and our team will confirm fitment for you.
Before replacing the ballast, it is worth confirming the fault lies with the control module rather than the HID globe itself. The simplest test is to swap the working globe from the opposite headlight into the non-working side. If the light still fails to ignite with a known-good globe installed, the ballast is the cause of the fault and should be replaced.
If your vehicle is displaying a LIN communication fault code (B2205 or B2206), this is a strong indicator that the ballast has failed electronically and must be replaced.

Q: Will this ballast fit my Hyundai i30?
A: Yes, provided your i30 is fitted with factory HID xenon headlights (not all variants are). Check that your original ballast carries the part number DHB-D1-LIN or 3Z921-01700. If it does, this is the correct direct replacement.
Q: Do I need to replace both ballasts?
A: Unlike HID globes, ballasts do not need to be replaced in pairs. You only need to replace the unit that has failed.
Q: Will this cause dashboard warning lights?
A: No. This OEM-specification replacement is designed to communicate correctly with the Hyundai and Kia factory LIN bus headlight system, ensuring no warning lights or fault codes are triggered after installation.
Q: How fast is delivery?
A: Express Delivery is included in the price. Orders are dispatched via Australia Post Express Satchel and typically arrive within 1–2 business days Australia-wide.
Q: What warranty is included?
A: All Pro Vision Lighting™ OEM replacement ballasts are backed by a comprehensive 2-year extended Australian warranty.
