4. Important Safety and Legal Information

Please read carefully before installation and use.

• Legal Compliance: The use of flashing brake lights may be subject to local and state regulations. Users are advised to verify the legality of such lights in their specific jurisdiction before installation and use. For example, some states like California may prohibit or restrict the use of strobe brake lights on public roads.
• Vehicle Compatibility: Some vehicles, particularly those with sensitive electrical systems or CANBUS (Controller Area Network Bus) systems, may experience compatibility issues. These can include dashboard error messages (e.g., "bulb out" warnings), hyper-flashing of turn signals (if used in that application), or interference with other electronic systems like keyless entry/start.
• Load Resistor Requirement: If your vehicle exhibits CANBUS errors or hyper-flashing after installation, a load resistor (sold separately) may be required to simulate the electrical load of a standard incandescent bulb and resolve these issues.
• Installation Safety: Always ensure the vehicle's ignition is off and the parking brake is engaged before attempting any electrical work. If unsure about the installation process, consult a qualified automotive technician.

5. Setup and Installation

Installation of the Syneticusa 7443 LED bulbs is generally straightforward, designed as a direct replacement for your vehicle's existing 7443 incandescent brake light bulbs. Always refer to your vehicle's owner's manual for specific instructions on accessing and replacing brake light bulbs.

1. Locate Brake Light Assembly: Access the rear brake light assembly, typically from inside the trunk or by removing the taillight housing.
2. Remove Old Bulb: Carefully twist and pull out the old 7443 incandescent bulb from its socket.
3. Insert New LED Bulb: Insert the Syneticusa 7443 LED bulb into the socket. Due to its non-polarity design, the orientation does not matter. Ensure it is firmly seated.
4. Test Functionality: Before reassembling, test the brake lights to ensure the new LED bulbs illuminate correctly and the strobe function activates upon braking.
5. Reassemble: Securely reassemble the taillight housing and any removed panels.

This diagram illustrates the high-performance 2835 LED chip used in the bulb and provides key dimensions: 0.78 inches in width and 1.98 inches in length. The 2835 chip offers a 20-degree wider view angle than 3528 chips and is three times brighter than regular bulbs.

6. Operation

Once installed, the Syneticusa 7443 LED brake light bulbs operate automatically with your vehicle's braking system.

• When the brake pedal is pressed, the bulbs will rapidly flash approximately 4 times.
• Immediately after the flashing sequence, the bulbs will illuminate steadily and remain lit as long as the brake pedal is depressed.
• This strobe-to-solid function is designed to provide an enhanced visual warning to drivers behind you, increasing safety.

7. Maintenance

Syneticusa LED bulbs are designed for long-term, maintenance-free operation. However, periodic inspection is recommended:

• Cleaning: If necessary, gently wipe the bulb's surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Inspection: Periodically check the bulbs for proper function (strobe and steady illumination) and ensure they remain securely seated in their sockets.
