Ford Galaxie 500 Back Up Light Switches
Ford Galaxie 500 Back up light switchs
Starting at $61.95, AutoBuffy stocks 1 back up light switches from Standard Ignition to fit your Ford Galaxie 500. 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.
Signs your Ford Galaxie 500 needs a new back up light switch
- Reverse lights do not illuminate at all when the transmission is shifted into reverse
- Reverse lights stay on continuously regardless of gear position
- Reverse lights flicker or cut in and out intermittently while backing up
- Backup camera or parking sensors fail to activate because the switch signal triggers those systems
- Vehicle fails a state safety inspection due to non-functioning reverse lights
- Scan tool or code reader shows a reverse lamp circuit fault or related drivetrain code
Which back up light switch should you buy for your Ford Galaxie 500?
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.
OE-Replacement (Manual Transmission)
Best for
Drivers with a manual gearbox wanting a direct plug-and-play fit
What you get
Thread pitch, connector, and calibration matched to factory specs; no wiring adapters needed
OE-Replacement (Automatic Transmission)
Best for
Automatic gearbox owners who need the reverse signal without a combined safety function
What you get
Dedicated reverse-signal switch sized and threaded for the automatic valve body or case
Neutral Safety / Inhibitor Switch (Combo Unit)
Best for
Automatic transmission vehicles where one switch handles both reverse lights and starter lockout
What you get
Single unit replacement that restores reverse lights and prevents starter engagement in gear
Heavy-Duty / Severe-Duty Switch
Best for
High-mileage vehicles, trucks with frequent towing, or off-road use with transmission stress
What you get
Reinforced contacts and sealed housing rated for higher vibration and heat cycles

Replacing the back up light switch on a Ford Galaxie 500
Easy⏱ 30–60 minutesSocket set or open-end wrenchesMultimeter (for pre- and post-installation testing)Penetrating oil (if switch is corroded in place)Drain pan (in case minor fluid seepage occurs)Electrical contact cleaner
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.
Frequently asked questions
How much does it cost to replace back up light switches on a Ford Galaxie 500?
Parts start at $61.95 for a Ford Galaxie 500 back up light switch at AutoBuffy. Labor is typically minimal — often under an hour — because the switch is externally mounted on the transmission case or shift linkage. Total out-of-pocket cost varies by shop rate, but this is one of the more affordable electrical repairs you can face.
Where is the back up light switch located on a Ford Galaxie 500?
On most vehicles the back up light switch threads directly into the transmission case or sits on the external shift linkage near the gear selector. On automatics it may be integrated into the neutral safety switch mounted on the side of the transmission. Consult your service manual or the part listing for your Ford Galaxie 500 to confirm the exact location.
Can I test the back up light switch on my Ford Galaxie 500 before replacing it?
Yes. Unplug the switch connector, shift into reverse, and use a multimeter set to continuity or resistance across the switch terminals. A good switch closes the circuit in reverse and opens it in every other gear. No continuity in reverse — or constant continuity in all gears — confirms the switch has failed and needs replacement.
Will a bad back up light switch affect anything other than the reverse lights on a Ford Galaxie 500?
On many modern vehicles, yes. The reverse-light signal also triggers the backup camera display, audible parking sensors, and some automatic braking or park-assist systems. On automatics with a combined neutral safety switch, a failure can also prevent the engine from starting or allow it to crank in gear, creating a safety risk.
Is replacing a back up light switch on a Ford Galaxie 500 a DIY job?
For most vehicles it is a straightforward DIY repair. The switch is externally accessible on the transmission, requires only basic hand tools, and does not require draining the transmission in most cases. Access can be tight depending on the engine bay layout of your Ford Galaxie 500, but the job is generally rated easy to moderate for a home mechanic.
How long does a back up light switch typically last on a Ford Galaxie 500?
Back up light switches are durable but do wear out over time. Most last many years under normal use, but heat cycles, transmission fluid exposure, vibration, and corrosion at the connector can shorten service life. Switches on vehicles driven in harsh climates or with high shift frequency tend to fail sooner than those in milder conditions.
