Detailed Description

The Marelli LRB320 HID ballast is used in Audi exterior lighting systems that rely on high intensity discharge technology. This component regulates the electrical output needed to start and maintain HID lamp operation, making it a critical part of the headlight system on select Audi R8 and Audi TT platform vehicles. If you are replacing a failed ballast on a 2007-2015 Audi TT Quattro, 2009-2015 Audi TTS Quattro, 2007-2014 Audi TT, 2011-2014 Audi TT RS Quattro, 2008-2012 Audi R8, or 2014-2016 Audi R8, this part number should be matched to the original application before installation. Marelli LRB320 is identified for these vehicle-specific lighting setups and is commonly searched as an Audi HID ballast replacement.

What It Helps Address

• Headlights that do not ignite
• Intermittent HID lamp operation
• Flickering or unstable HID lighting
• Lighting system faults tied to ballast failure
• Loss of proper HID startup voltage

Installation Notes and Tips

Verify the original ballast part number and connector style before installation. Confirm vehicle year, model, and lighting configuration on the Audi R8 or Audi TT family application. Because HID systems operate at high voltage, installation should be performed with the lighting circuit powered down and handled according to factory service procedures.

Quality Assurance

Marelli is an established OE supplier in automotive electrical and lighting components. The LRB320 is built for the specified Audi applications and should be selected by exact fitment match for reliable service.
