Frequently Asked Questions

Q: My Hyundai/Kia LED headlight works but the matrix function doesn’t — is this the connector?
A: Yes. Corroded LED matrix CAN bus pins (pins 3–4) or individual segment control pins (pins 16–17) cause matrix function failure while basic LED illumination continues to work. This is a common symptom of partial connector corrosion.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
