1942-1946 Hudson Commodore Series 27 Brake Light Switch Replacement
Keep your classic Hudson safe and its brake lights working reliably with a new switch.
- The most common signs of failure are brake lights that don't work or stay on constantly.
- For this vehicle, the brake light switch is a hydraulic pressure switch, not a mechanical one on the pedal arm.
- Standard Ignition is a reputable brand for classic American car parts, making their aftermarket switch a reliable choice.
- Replacing the switch requires opening the brake lines, so you must bleed the brakes afterward.
Symptoms of a Failing Brake Light Switch
A bad brake light switch on your Hudson Commodore will typically show one of two main symptoms. Either your brake lights will not turn on at all, or they will stay on constantly, even when you are not pressing the brake pedal. You might also notice the lights flickering or only working when you press the pedal very hard. Since the brake lights are your primary way of signaling to drivers behind you, any of these symptoms indicate a part that needs immediate attention.
Choosing the Right Aftermarket Switch
For a vintage vehicle like a 1942-1946 Hudson, finding New Old Stock (NOS) OEM parts can be difficult and expensive. Furthermore, parts that have sat on a shelf for decades may not be reliable. A new aftermarket brake light switch is often the most practical and reliable choice. Standard Ignition (Standard Motor Products) is a well-known aftermarket brand that has been around for a very long time and is a common choice for classic American vehicles. Their parts are generally considered to be of good quality, often meeting or exceeding original specifications. The available Standard Ignition switch is a modern, reliable replacement that ensures your brake lights function correctly.

Pro Tip: When replacing a hydraulic brake light switch, you will be opening the brake system. Be prepared to bleed the brakes afterward to remove any air that gets into the lines. Also, check what type of brake fluid your system uses, as some modern switches are not compatible with silicone brake fluid.
Frequently Asked Questions
Is it difficult to replace the brake light switch on my Hudson?
No, it is generally not a difficult job. The switch is typically screwed into the master cylinder or a nearby brake line junction. The main challenge is the need to bleed the brakes after installation to ensure there is no air in the system. For a DIYer with basic tools, this should take less than an hour.
Are there any recalls for the brake light switch on my Hudson Commodore?
There are no specific recalls found for the brake light switch on the 1942-1946 Hudson Commodore. Given the age of the vehicle, any safety campaigns would have expired many decades ago.
Why do my brake lights work but my tail lights don't (or vice-versa)?
The tail lights (for visibility at night) and brake lights run on separate circuits, though they use the same bulb. If the tail lights work but the brake lights don't, the problem is almost certainly the brake light switch, the fuse, or the specific filament in the bulb. If the brake lights work but the tail lights don't, the issue is likely the headlight switch, a different fuse, or the other filament in the bulb.
Why choose a new aftermarket switch over a used original?
Hydraulic brake light switches are known to fail over time due to wear and tear or contamination in the brake fluid. A used switch from another 80-year-old car has an unknown history and could fail quickly. A new aftermarket switch from a reputable brand like Standard Ignition is built with modern materials and is 100% tested, offering much greater reliability.
