A Guide to the Brake Light Switch for the 2019-2022 Honda Insight
If your Insight has brake light problems, won't start, or has multiple warning lights on, the brake light switch could be the cause.
- A bad brake light switch can prevent your Insight from starting or shifting out of Park.
- Driving without working brake lights is illegal and extremely dangerous; get the issue fixed immediately.
- This is a simple, low-cost repair that a DIYer can typically complete in under an hour.
- Always check for related recalls or TSBs, as a BCM software issue can mimic the symptoms of a bad switch.
Is Your Honda Insight's Brake Light Switch Failing?
A faulty brake light switch can cause confusing problems that might not seem related to the brakes at first. Because this switch communicates with so many different systems in your Insight, a failure can trigger a range of symptoms. Recognizing these signs early can save you from a major headache, like being unable to start your car or getting stranded because you can't shift out of Park.
Common Symptoms of a Bad Brake Light Switch
- Brake Lights Don't Work: The most obvious and dangerous symptom is when your brake lights do not turn on when you press the pedal.
- Brake Lights Stay On: The switch can also fail in the 'on' position, leaving your brake lights illuminated constantly and draining your 12-volt battery.
- Car Won't Start: Your Insight has a push-button start that requires a signal from the brake light switch to allow the engine to turn on. If the switch is bad, the car won't know you're pressing the brake and will refuse to start.
- Can't Shift Out of Park: For safety, an automatic transmission has a shift interlock that prevents you from shifting out of Park unless the brake is applied. A bad switch can leave you stuck.
- Dashboard Warning Lights: A failing switch can cause warning lights for the ABS, traction control, or brake system to appear on your dash.
- Cruise Control Issues: The cruise control system uses the brake switch to disengage. If the switch is faulty, your cruise control may not work at all.
Vehicle-Specific Issues for 2019-2022 Honda Insight
While there are no specific recalls for the brake light switch on this generation of Insight, owners should be aware of two related items:
- NHTSA AEB Investigation: The National Highway Traffic Safety Administration (NHTSA) has an ongoing engineering analysis into the 2019-2022 Insight for unexpected activation of the Automatic Emergency Braking (AEB) system. This is not directly caused by the brake light switch but is a significant issue related to the vehicle's braking electronics.
- BCM Software Recall: Some 2019-2020 Insight models were recalled for a Body Control Module (BCM) software error that could cause malfunctions in various systems, including the exterior lights. It's worth checking if your vehicle was affected by this recall, as it can cause symptoms similar to a bad brake light switch.
Choosing the Right Aftermarket Part
When replacing the brake light switch, you have the choice between an original equipment manufacturer (OEM) part from Honda and an aftermarket part. For the 2019-2022 Insight, the quality difference is often minimal for a simple switch like this.
- OEM: An OEM part is the exact same one your vehicle was built with. There is some price confusion for this part; some dealer sites list it for under $25, while parts estimators place it closer to $95.
- Aftermarket (Standard Ignition): Brands like Standard Ignition (also known as Standard Motor Products) produce reliable replacement parts that meet or exceed OEM specifications. They are a well-regarded manufacturer in the industry. An aftermarket switch from a quality brand is a dependable and cost-effective choice.
Pro Tip: Before assuming the switch is bad, always check the simple things first. Make sure the brake light fuse isn't blown and that the bulbs themselves haven't burned out.
Brake Light Switch Replacement Cost
The cost to replace the brake light switch on a 2019-2022 Insight is reasonable. The part itself is not overly expensive, and the labor is straightforward.
| Part/Service | Estimated Cost |
|---|---|
| Shop Labor | $61 - $90 |
| New OEM Part | $20 - $95 |
| New Aftermarket Part | $85 - $95 |
Frequently Asked Questions
Where is the brake light switch located on my Insight?
The brake light switch is mounted on a bracket directly above the brake pedal arm, under the driver's side dashboard. It can be in an awkward spot to see and reach.
Can I replace the brake light switch myself?
Yes, this is a very DIY-friendly repair for most people with basic tools. The job typically takes less than an hour. It involves disconnecting the battery, unplugging the electrical connector, and twisting or unbolting the old switch to remove it.
Do I need to adjust the new brake light switch?
Yes, proper adjustment is critical. The new switch must be installed so that the brake lights turn on with a small amount of pedal travel (typically 1/4 to 1/2 inch) and turn off completely when the pedal is released.
Is it safe to drive with a bad brake light switch?
No. If your brake lights are not working, it is extremely dangerous and illegal to drive. Other drivers will have no warning when you are slowing or stopping. If the switch is failing, it's best to get it replaced immediately.
