Jeep Cherokee Back Up Light Switch Guide for 1974-1980 Models
If your reverse lights have failed, the solution is often a simple and affordable switch replacement.
- For automatic transmissions, this part is a combined Neutral Safety Switch and Back Up Light Switch.
- Failure is common and symptoms include no reverse lights or a no-start condition.
- Verify your transmission type (automatic vs. manual) before ordering, as the parts are different.
- Aftermarket is the only practical option; Standard Ignition offers a quality focus while Crown offers value and availability.
Is Your Back Up Light Switch Failing?
A failing back up light switch on a classic Jeep Cherokee is a common issue. Given the age of the vehicle, these switches wear out, get dirty, or simply break. The most obvious sign of a problem is when your reverse lights stop working altogether. You might also notice they only work when you jiggle the shifter, which points directly to a worn switch.
For owners with an automatic transmission, the symptoms can be more serious. Since the switch is part of the Neutral Safety Switch, a failure can prevent your Jeep from starting at all, or worse, allow it to start in any gear, which is a significant safety risk.
Choosing the Right Aftermarket Back Up Light Switch
For a vintage vehicle like the 1974-1980 Cherokee, finding a New Old Stock (NOS) Mopar part is not a realistic option. The aftermarket is your go-to source, offering parts that get the job done without a difficult search. Here’s a look at the available brands.
Tier 1: Reliability and Quality
Standard Ignition (Standard Motor Products): Standard is a well-known manufacturer of automotive electrical parts. Their components are generally regarded as high-quality replacements. Standard states that their parts are 100% tested to verify mechanical and electrical performance. For a critical component that can affect starting your vehicle (on automatic models), choosing a brand with a strong reputation for quality control like Standard Ignition is a wise investment for peace of mind.
Tier 2: Value and Availability
Crown Automotive: Crown is a staple in the Jeep aftermarket, known for providing a huge range of replacement parts, especially for older and discontinued models. For many hard-to-find parts, Crown is sometimes the only option. However, owner feedback on Crown parts is often mixed. While some have no issues, others report problems with fitment and a shorter lifespan compared to other brands. Crown represents a budget-friendly choice that keeps many classic Jeeps on the road, but be aware that quality can be inconsistent.

Frequently Asked Questions
Is the back up light switch the same as the neutral safety switch?
On 1974-1980 Jeep Cherokees with an automatic transmission, yes. The two functions are combined into a single part. If you have a manual transmission, they are two separate parts, and you only need the dedicated back up light switch.
How do I know if my back up light switch is bad?
The most common symptom is that your reverse lights don't turn on. You can check the bulbs and fuses first. If those are good, the switch is the next logical culprit. On automatic models, if you also have trouble starting the vehicle or it starts in gear, the Neutral Safety Switch/Back Up Light Switch assembly is almost certainly the problem.
Can I replace the back up light switch myself?
Yes, this is a DIY-friendly job for most home mechanics. On some models, the switch is mounted on the steering column near the pedals and is very easy to access and replace in minutes. On other models, it is located on the transmission itself, which can be slightly more difficult to reach. Basic hand tools are all that is typically required.
What is the most common mistake when ordering this part?
The most common mistake is ordering the wrong part for your transmission type. Double-check if your Cherokee is an automatic or a manual. The switches are different and not interchangeable. For automatic models, you are buying a Neutral Safety Switch, and for manual models, you are buying a simpler Back Up Light Switch.
