- Replacement is straightforward and can be done by most owners with basic tools in under an hour.
- For long-term reliability, choose a quality brand like Standard Ignition and consider adding a headlight relay kit.
- There are no recalls for this part; failures are due to the component's age.
Is Your Headlight Switch Failing?
In a classic truck like the 1960-1965 Suburban, the headlight switch is a hardworking part. Over decades, the internal contacts can wear out, corrode, or overheat. This can lead to some noticeable and potentially dangerous problems.
One of the most common symptoms is headlights that flicker or turn off and on by themselves. This happens because these older switches have a built-in circuit breaker. When the switch gets old and corroded, resistance builds up and creates heat, causing the breaker to trip and reset continuously. You might also notice that the switch only works in certain positions, the high beams won't stay on, or the dash lights won't dim properly. In the worst-case scenario, the switch fails completely, leaving you with no lights at all.
Choosing Your Aftermarket Headlight Switch
For a vehicle of this era, finding a "new old stock" (NOS) OEM part is nearly impossible and often very expensive. The good news is that the aftermarket provides reliable and affordable solutions. The two main tiers you'll encounter are value brands and premium brands.
| Brand Tier | Example Brand | Typical Price | Best For |
|---|---|---|---|
| Value | Replacement | $27.74 - $45.00 | Owners on a tight budget who need a functional, basic switch that gets the job done. |
| Premium | Standard Ignition | $50.00 - $89.08 | Owners looking for higher quality materials and construction for better long-term reliability. Standard Motor Products is a well-regarded brand in the aftermarket. |
Pro Tip: While replacing the switch, consider adding a headlight relay harness. This simple upgrade takes the high electrical load off the new switch, routing power directly from the battery to the headlights. This not only dramatically extends the life of your new switch but can also make your headlights noticeably brighter.
Frequently Asked Questions
Is it hard to replace the headlight switch myself?
No, this is a very DIY-friendly job for most owners. The process involves disconnecting the battery, reaching under the dash to find a small spring-loaded button on the switch body, pressing it to release the knob and shaft, unscrewing a retaining nut on the dash, and then unplugging the old switch. Installation is the reverse of removal.
Why do my headlights flash on and off while driving?
This is a classic sign of a failing headlight switch in a 1960s GM truck. The switch has an internal thermal circuit breaker that is tripping due to high resistance from age and corrosion. It's a clear warning that the switch needs to be replaced soon.
Do I need a special tool to remove the switch?
Usually, no. The main tool needed is a way to unscrew the bezel nut that holds the switch to the dashboard. Sometimes this can be done by hand, or carefully with needle-nose pliers or a flathead screwdriver. The knob itself is removed by pressing a button on the switch body under the dash.
Are there any recalls on the headlight switch for my Suburban?
No. There are no active recalls or Technical Service Bulletins (TSBs) from GMC or the NHTSA for the headlight switch on the 1960-1965 GMC Suburban. Any issues experienced are due to the age and normal wear of the original component.
