Modern headlight assemblies consolidate all lighting functions into a single multi-pin connector, which means a single corroded pin can cause multiple simultaneous failures. The most common failure pattern is corrosion on the ground pins (even-numbered pins), which causes multiple functions to fail simultaneously — DRL, position light, and turn signal all going out at the same time. This pattern is frequently misdiagnosed as a failed headlight module before the connector is inspected.
Q: My headlight has multiple functions out simultaneously — is it the connector?
A: Multiple simultaneous headlight function failures almost always indicate a corroded ground pin in the multi-pin connector rather than multiple individual LED or bulb failures. Inspect the connector before replacing the headlight assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
