Symptoms of a Failing Back Up Light Switch
A bad back up light switch has a few common and easy-to-spot symptoms. Because the part is a simple on/off switch, failures are usually straightforward.
- Reverse Lights Don't Turn On: This is the most common sign of a failed switch. If your bulbs and fuse are good, the switch is the next logical part to check.
- Lights Work Intermittently: You might notice the lights flicker or only work when you jiggle the shifter. This points to a worn or failing switch that isn't making a consistent connection.
- Reverse Lights Stay On: Less common, but the switch can fail in the 'on' position, causing your backup lights to stay illuminated even when you are not in reverse.
Choosing the Right Aftermarket Switch
For a vehicle like the 1971-1980 Dodge Colt, finding new original equipment (OEM) parts from a dealer is no longer possible. Your main choices are a new aftermarket part or a used/New Old Stock (NOS) original part.
Aftermarket vs. Used OEM
While a used or NOS OEM part (often made by Mitsubishi) might seem appealing, they can be difficult to find, expensive, and may have degraded from age even if unused. A new aftermarket switch from a reputable brand like Standard Ignition (Standard Motor Products) is often the most practical and reliable choice. Standard is a long-established company known for producing quality electrical components. While quality can vary across the aftermarket industry, Standard is generally considered a dependable source for parts for vintage vehicles.
Typical Costs for Replacement
Replacing the back up light switch is an affordable repair. The part itself is not expensive, and labor is minimal if you take it to a shop.
| Part Type | Part Cost | Shop Labor Cost | Total Estimated Cost |
|---|---|---|---|
| New Aftermarket (Standard Ignition) | $33 - $48 | $50 - $100 | $83 - $148 |
| New OEM (NOS) | Not Widely Available | $50 - $100 | Varies Greatly |
| Used OEM | $15 - $50+ (if found) | $50 - $100 | $65 - $150+ |
Cost estimates are for reference only and may vary based on your location, vehicle condition, and the specific repair shop.
Known Issues, Recalls, or TSBs
Searches of the National Highway Traffic Safety Administration (NHTSA) database and other technical resources did not reveal any specific recalls or Technical Service Bulletins (TSBs) for the back up light switch on the 1971-1980 Dodge Colt. This is common for a vehicle of this age, as such records were not as extensively digitized or may not have been issued for a simple component like this switch.
Frequently Asked Questions (FAQ)
Can I replace the back up light switch myself?
Yes, this is a great DIY job for a beginner. The switch is usually located on the exterior of the transmission. The process typically involves disconnecting the electrical connector, unscrewing the old switch, and screwing in the new one. You may need a wrench and a drain pan, as a small amount of transmission fluid might leak out when the switch is removed.
My reverse lights don't work. How do I know it's the switch?
First, check the bulbs to make sure they aren't burned out. Then, check the fuse for the lighting circuit. If both are okay, the switch is the most likely culprit. A simple test is to access the switch's electrical connector, bypass it with a small jumper wire, and see if the lights turn on (with the key in the 'on' position). If they do, the switch is bad.
Is it safe to drive with a broken back up light switch?
While the car will still drive normally, it is a safety risk. Reverse lights are essential for signaling your intentions to others. Driving without them increases the risk of a low-speed collision when backing up and may be illegal in your state, leading to a failed inspection or a ticket.
What's the difference between a manual and automatic transmission switch?
The switches can be different. On many automatic cars, the back up light switch is integrated into a larger component called the Neutral Safety Switch, which prevents the car from starting in gear. On manual transmissions, it's a simple, separate switch. Always ensure you are buying the correct part for your specific transmission type.
Why is my Dodge Colt also called a Mitsubishi?
During this period, the Dodge Colt was a "captive import," meaning it was built by Mitsubishi and sold under the Dodge brand. Your Colt is essentially a rebadged Mitsubishi Galant or Lancer, depending on the year. This is why some parts, like this switch, may have a Mitsubishi part number.
