⚠️ HONEST DISCLOSURE - PLEASE READ

This ballast is UNTESTED and sold AS-IS. I do not have the proper D1S/D3S xenon bulb or vehicle harness to test functionality. The unit looks good physically, but I cannot guarantee it works. You're getting a significant discount (40-50% off) in exchange for taking this risk.

30-day returns accepted if non-functional when properly tested.

📋 What I CAN Confirm (Visual Inspection)

✓ Housing is intact with no visible cracks or damage
✓ All 8 connector pins appear clean and undamaged
✓ Red high-voltage seal gasket is intact
✓ Specification label is fully legible
✓ No burning smell or obvious signs of failure
✓ Mounting brackets are not broken

❌ What I CANNOT Confirm

✗ Whether it powers on and functions correctly
✗ If it can ignite and maintain a xenon bulb
✗ Why it was removed from the vehicle (unknown history)
✗ Any electrical functionality whatsoever

💬 Final Thoughts

I'm selling this part honestly because I simply cannot test it. The physical condition looks good to my eyes, but I make no guarantees about functionality. You're taking a calculated risk at a heavily discounted price.

If that works for you - great! If not, I completely understand and encourage you to look for a tested unit elsewhere.

Questions before purchasing? Message me - I'll answer honestly every time.
