Q: My Hyundai has multiple lighting functions out simultaneously — is it the connector?
A: Multiple simultaneous lighting failures (e.g. DRL + turn signal, or tail + brake light) on Hyundai/Kia vehicles almost always indicate a corroded ground pin in the 10-pin connector rather than multiple individual bulb or LED failures. Inspect the connector before replacing the lighting assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
