Turn Signal Switch & Lighting Control Unit

This steering-column control helps you command the vehicle’s indicators and exterior lights without taking your hands far from the wheel. It’s a safety-critical item because it tells other drivers what you plan to do and ensures you can see and be seen at night ?.

Why this part is needed

Modern Mitsubishi setups route indicator and headlamp requests through a multi-function switch. It keeps lighting functions organized, reduces driver distraction, and delivers clean electrical signals to the lighting circuit or body control module.

How it works

Inside the stalk are precision contacts and a return-cancel mechanism. When you move the lever, it closes specific circuits for left/right turn, high/low beam, and parking/head lamps. A spring-loaded cam cancels the turn signal after the steering wheel returns to center ?.

What happens if it’s broken

Common symptoms include indicators not flashing, high beam stuck or inoperative, lights cutting out over bumps, or signals that won’t cancel. A faulty unit can lead to poor road communication, traffic violations, and higher risk in lane changes or night driving ⚠️.

Technician tip

If you notice intermittent operation or a “loose” stalk feel, inspect the switch assembly and connector for heat marks, worn contacts, or broken detents before it causes total lighting failure.
