Q: My Hyundai DRL is out but low beam works — is it the connector?
A: Yes. Isolated DRL failure with functioning low beam on Hyundai/Kia platforms is a classic symptom of corrosion on Pins 5–6 (DRL/position light circuit) in the 6-pin headlight connector. Inspect the connector before replacing the DRL module or headlight assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
