Chrysler Imperial Brake Light Switch Guide: 1961-1966
Keep your classic Imperial's brake lights working reliably with the right replacement switch.
- First, confirm if your Imperial has the early hydraulic switch (on the master cylinder) or the common mechanical switch (on the pedal).
- The most common failure is brake lights not working at all, which is a critical safety issue.
- Standard Ignition is a reliable and affordable aftermarket brand for this part.
- DIY replacement is very feasible, requiring less than an hour and basic tools, with the main difficulty being the awkward location under the dash.
Is Your Imperial's Brake Light Switch Mechanical or Hydraulic?
Before buying a new brake light switch for your 1961-1966 Imperial, you need to know which type you have. Chrysler made a change during this period.
- Hydraulic Switch: Some early 1961 models use a hydraulic pressure switch. This switch screws into the master cylinder and is activated by brake fluid pressure. These are known to become less reliable over time, sometimes requiring very hard pedal pressure to work.
- Mechanical Switch: Mid-1961 and all later models through 1966 use a mechanical switch. This switch is mounted on a bracket under the dashboard, activated directly by the movement of the brake pedal arm. This is the more common and generally more reliable type.
Pro Tip: Check your car first. Look for a switch with two wires on the master cylinder (hydraulic) or a small plunger-style switch attached to the brake pedal assembly under the dash (mechanical). This guide focuses on the more common mechanical aftermarket replacement.
Symptoms of a Failing Brake Light Switch
A bad brake light switch will give you clear warning signs. Look out for these common symptoms:
- Brake Lights Don't Work: The most obvious and dangerous symptom. If the bulbs and fuse are good, the switch is the next logical culprit.
- Brake Lights Stay On: The switch can fail in the 'on' position, leaving your brake lights permanently lit. This will drain your battery and confuse other drivers.
- Intermittent or Flickering Lights: The internal contacts of the switch can wear out, causing the lights to work only sometimes or appear dim.
Choosing the Right Aftermarket Part
For a classic car like the 1961-1966 Imperial, the distinction between OEM and aftermarket is different. New Original Equipment (OEM) parts are no longer made. Instead, you might find New Old Stock (NOS) parts, which are original parts that have been sitting on a shelf for decades. These can be expensive and may not be better than a modern replacement.
Standard Ignition (Standard Motor Products/SMP): This is the most widely available aftermarket brand for your Imperial. Standard Ignition is a long-established company with a generally good reputation for producing reliable replacement parts for classic vehicles. For a simple part like a mechanical brake light switch, their quality is more than adequate for a daily driver or show car.
There are no known recalls or Technical Service Bulletins (TSBs) from Chrysler or the NHTSA for the brake light switch on the 1961-1966 Imperial.
Brake Light Switch Replacement Cost
Replacing this switch is an affordable repair. The aftermarket part is inexpensive, and labor is minimal if you have a shop do it.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (Standard Ignition) | $15 - $20 |
| New Old Stock (NOS Mopar) | $50 - $60+ (if you can find one) |
| Shop Labor | $50 - $75 |
Frequently Asked Questions (FAQ)
Can I replace the brake light switch myself?
Yes, this is a great DIY job. The main challenge is the location, as you'll be working under the dashboard. The process involves disconnecting the battery, unplugging the old switch, removing a clip or bolt, and installing the new one. It usually takes less than an hour with basic tools.
Where is the brake light switch located on my Imperial?
For the common mechanical type, it's located under the driver's side dashboard, mounted to a bracket on the brake pedal assembly. You will see a small switch with a plunger that makes contact with the brake pedal arm.
What if my brake lights still don't work after replacing the switch?
If a new switch doesn't solve the problem, check the simple things first: the fuse and the brake light bulbs. After that, check for a bad ground connection at the tail lights or a problem in the wiring. The power for the brake lights often runs through the turn signal switch in the steering column, which can also be a point of failure.
Do I need to adjust the new brake light switch?
Yes, proper adjustment is key. The switch needs to be positioned so the brake lights come on as soon as you press the pedal, but are completely off when the pedal is released. Many mounting brackets have slotted holes to allow for this adjustment.
