=== Common 280ZX Headlight Dim/Fault Issue ===

The usual culprit for dim or failed headlights on the 280ZX (S130) is the
'''backside of the combination switch''' where the headlight harness plugs in.

This switch has a known weak point — a single pin that often fails due to
'''electrical overload'''. Over time, the pin heats up, develops
carbon buildup, and increases resistance in the circuit.
This resistance can cause the headlamp to become dim or fail completely.

The carbon acts like an insulator, blocking proper current flow to the lights. Cleaning or replacing the affected pin can restore headlight performance, but many owners choose to install a headlight relay harness to prevent recurrence.
