Specialist Inspection Points

Before shipping these high-value optics (often retailing for $4,000–$5,500+ per pair), ensure your team verifies:

1. Mounting Brackets: Check that all three main plastic mounting tabs are original and have no stress fractures.

2. LED Modules: Verify that the silver control modules (ballasts) are securely attached to the rear of the housing.

3. Ventilation Caps: Ensure the rubber “breathable” caps are present to prevent internal condensation.

4. Wiring Pins: Inspect the main harness plug for any corrosion or bent pins.

Technical Installation Note

If the target vehicle is currently equipped with Bi-Xenon lights, upgrading to these Full LED units is not a simple plug-and-play swap. It requires a specific conversion harness and extensive PIWIS III coding to map the LED signals and activate the PDLS+ high-beam assist. However, for a vehicle already equipped with LED lights, these are a direct cosmetic swap.
