Dodge Charger Back Up Light Switch Guide: 1969-1987
Keep your classic Charger safe and legal by fixing your reverse lights.
- For 1969+ automatic Chargers, the back up light function is part of the 3-prong Neutral Safety Switch (NSS) on the transmission.
- Failure symptoms are simple: lights don't work, stay on, or flicker.
- Replacement is an easy DIY job, requiring only basic tools and safe access under the vehicle.
- Aftermarket brands like Standard Ignition are common, reliable replacements for these classic vehicles.
Is Your Back Up Light Switch Failing?
A bad back up light switch on a classic Dodge Charger is both a safety hazard and a reason to fail a vehicle inspection. The symptoms are usually straightforward and easy to spot. Because this part is a simple mechanical switch, failure is typically due to worn internal contacts or a broken plunger mechanism.
Symptoms of a Bad Switch
- Reverse Lights Don't Turn On: This is the most common sign of a failed switch. When you shift into reverse, the lights do not illuminate at all.
- Reverse Lights Stay On: The switch can fail in the 'on' position, causing the reverse lights to stay lit even when you are in park, neutral, or a forward gear. This can confuse other drivers and quickly burn out your bulbs.
- Lights Work Intermittently: The lights may flicker or only work sometimes when you shift into reverse. This often points to worn internal contacts inside the switch.
- Lights On in the Wrong Gear: If your reverse lights come on in Drive or another gear, the problem might be the switch or an internal transmission component that activates it.
Important Note for 1969+ Charger Owners
On many 1969 and later models with an automatic transmission, the back up light switch is integrated into the Neutral Safety Switch (NSS). This is a 3-prong switch located on the transmission case. If you also have trouble starting the car in Park or Neutral, the entire NSS assembly is likely the culprit.
Choosing the Right Aftermarket Back Up Light Switch
For vehicles as old as the 1969-1987 Charger, new OEM Mopar parts are virtually nonexistent. The market consists of new aftermarket parts, which are widely available and generally reliable. The key is to buy the correct part for your specific year and transmission type.
| Brand Tier | Our Brands | Typical Price | Quality & Notes |
|---|---|---|---|
| Standard Replacement | Standard Ignition | $33 - $38 | A widely recognized and trusted brand in the aftermarket. Standard Motor Products (SMP) parts like the NS-11 are commonly used by Charger owners and are known to be reliable replacements. |
| Economy | Facet | $26 - $30 | Facet offers a more budget-friendly option. While not as commonly discussed in classic Mopar forums, they are an established Italian manufacturer of electrical components and provide a functional replacement for a lower cost. |
OEM vs. Aftermarket Quality
For a simple switch like this on a classic car, a quality aftermarket part from a known brand like Standard Ignition is more than adequate. These parts are designed to meet or exceed the original factory specifications. The most critical factor is ensuring you order the correct switch for your automatic or manual transmission, as they are different parts.
Frequently Asked Questions (FAQ)
Where is the back up light switch located on my Charger?
For 1969-1987 Chargers, the switch is mounted on the transmission. On automatic models, it's a 3-prong switch on the side of the transmission case. On 4-speed manual models, it's a 2-prong switch, also on the transmission. Note: This is different from 1968 models, where the switch for automatic cars was located inside the center console.
Can I replace the back up light switch myself?
Yes, this is a very DIY-friendly job. It involves safely raising the vehicle, locating the switch on the transmission, unplugging the electrical connector, and unscrewing the old switch. Installation is the reverse of removal. No special tools are required beyond basic hand tools.
I replaced the switch and the lights still don't work. What now?
If a new switch doesn't solve the problem, check the following:
1. The fuse for the lighting circuit.
2. The bulbs themselves.
3. The wiring and connector for corrosion or breaks.
4. On automatic transmissions, there is an internal lever (sometimes called a 'rooster comb') that physically activates the switch. This component can wear out or break, meaning the new switch isn't being activated.
Are there any recalls for the back up light switch on my Charger?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) related to the back up light switch for the 1969-1987 Dodge Charger. Recalls found for the Dodge Charger nameplate relate to much newer models with modern electronics.
Technical Specifications
Varies by transmission. Automatic transmissions typically use a 3-prong switch that combines the neutral safety and back up light functions. Manual transmissions use a separate 2-prong switch.
