Starting at $64.95, AutoBuffy stocks 1 back up light switches from Standard Ignition to fit your Lincoln Lincoln. The back up light switch signals the reverse lights to illuminate when you shift into reverse, giving drivers behind you a warning and improving visibility. A failed switch leaves your reverse lights dark, creating a safety hazard and a likely inspection failure.
The right back up light switch depends on your transmission type, the switch's mounting location on the gearbox, and whether you want an OE-equivalent fit or a budget replacement. Automatic and manual transmissions use different switch designs, and some vehicles use a neutral safety switch that combines reverse-light and starter-enable functions into one unit.
| Option | Best for | What you get |
|---|---|---|
| OE-Replacement (Manual Transmission) | Drivers with a manual gearbox wanting a direct plug-and-play fit | Thread pitch, connector, and calibration matched to factory specs; no wiring adapters needed |
| OE-Replacement (Automatic Transmission) | Automatic gearbox owners who need the reverse signal without a combined safety function | Dedicated reverse-signal switch sized and threaded for the automatic valve body or case |
| Neutral Safety / Inhibitor Switch (Combo Unit) | Automatic transmission vehicles where one switch handles both reverse lights and starter lockout | Single unit replacement that restores reverse lights and prevents starter engagement in gear |
| Heavy-Duty / Severe-Duty Switch | High-mileage vehicles, trucks with frequent towing, or off-road use with transmission stress | Reinforced contacts and sealed housing rated for higher vibration and heat cycles |
Disconnect the battery, locate the switch on the transmission case or shift linkage, and unplug the wiring harness connector. Unscrew the old switch — applying penetrating oil first if corroded — and thread in the new switch by hand before snuggling it down snugly with a wrench to avoid over-tightening. Reconnect the harness and battery, then shift into reverse to confirm the lights illuminate before returning the vehicle to service.
