2015–2023 Dodge Charger Rapid Fire Third Brake Light Harness Guide
The 2015–2023 Dodge Charger is known for its iconic full-width LED taillight design, making it one of the most recognizable modern muscle cars on the road. While the factory third brake light performs its intended function, many owners choose to upgrade it with a Rapid Fire Third Brake Light Harness that adds a quick flashing sequence when the brakes are first applied.
One of the most common questions is:
Can you make the third brake light flash when braking without modifying the factory wiring?
The answer is yes.
The 2015–2023 Dodge Charger Rapid Fire Third Brake Light Harness is a true plug-and-play solution that installs inline with the factory wiring and automatically creates a rapid flashing sequence before the third brake light remains solid during braking.
This guide explains how the harness works, why many Charger owners install one, and how it improves both visibility and style.
Why Upgrade to a Rapid Fire Third Brake Light?
A rapid flashing third brake light is one of the easiest ways to modernize your Charger while improving rear visibility.
Many owners install this upgrade because it offers:
- Increased visibility during braking
- Modern performance-inspired appearance
- Factory-style installation
- Plug-and-play design
- No permanent wiring modifications
- Added attention from following drivers
The quick flash sequence helps make your vehicle more noticeable when the brakes are first applied before returning to normal brake light operation.
How Does the Rapid Fire Harness Work?
The harness installs directly between the factory third brake light connector and the vehicle's wiring.
When the brake pedal is pressed:
- The third brake light rapidly flashes several times.
- After the flash sequence, the light automatically stays illuminated as a normal brake light.
- Once the brake pedal is released, the harness resets and is ready for the next braking event.
This allows the third brake light to provide additional visual attention without changing its normal operation after the flash sequence.
Maintains Factory Brake Light Functionality
One of the biggest advantages of this harness is that it maintains the factory behavior of the brake light.
After the rapid flash sequence:
- The third brake light remains solid while the brake pedal is held.
- The harness automatically resets when the brake pedal is released.
- The rapid flash sequence repeats each time the brakes are applied.
This creates an OEM-style operation with an added performance-inspired effect.
