Installation
- Locate the Bulb: Identify the incandescent bulb you wish to replace (e.g., brake light, tail light, turn signal light). Refer to your vehicle's owner's manual for specific bulb locations and access procedures.
- Remove the Old Bulb: Carefully twist and pull out the old incandescent bulb from its socket.
- Insert the LED Bulb: Insert the BRISHINE LED bulb into the socket. Due to its non-polarity design, it will function regardless of insertion direction.
- Test Functionality: Before reassembling, test the new LED bulb to ensure it illuminates correctly for its intended function (brake, tail, turn signal).
- Address Hyper Flash (if applicable): If installing for turn signal lights and experiencing rapid flashing (hyper flash), a load resistor or flash relay may be required. This is a common characteristic when replacing incandescent turn signal bulbs with LEDs due to lower power draw.
- Secure Assembly: Once confirmed working, reassemble any removed components (e.g., taillight housing).
The BRISHINE LED bulbs are designed for a direct plug-and-play installation, matching the size of original incandescent bulbs for a perfect fit within the lamp housing.

Operating Instructions
These LED bulbs are suitable for various automotive applications including brake lights, tail lights, turn signal lights, and the center high mount stop (3rd brake) light. They feature a dual-function capability with a high intensity of 3.5W for brake lights and a lower intensity of 0.9W for tail lights, providing a significant brightness difference for clear signaling.
The 360-degree beam pattern ensures uniform light distribution, making your vehicle more visible to other drivers and enhancing overall driving safety.
Maintenance
BRISHINE LED bulbs are designed for long-term performance with a lifespan exceeding 30,000 working hours. This significantly surpasses the typical lifespan of incandescent bulbs, reducing the need for frequent replacements. The full aluminum housing and built-in Constant Current IC Driver contribute to quicker heat dissipation and stable performance, minimizing maintenance requirements.
No specific routine maintenance is required for the bulbs themselves beyond ensuring they are free from dirt or debris that might obstruct light output. Periodically check for proper illumination of all lights.
Troubleshooting
- Hyper Flash: If your turn signals flash rapidly after installing LED bulbs, this is a common issue due to the lower power draw of LEDs compared to incandescent bulbs. To resolve this, install a compatible load resistor or an LED-specific flash relay. Consult your vehicle's service manual or an automotive professional for guidance on selecting and installing these components.
- Bulb Not Lighting Up: Ensure the bulb is correctly seated in the socket. Due to the non-polarity design, incorrect orientation is unlikely, but re-seating can sometimes resolve connection issues. Verify that the vehicle's electrical system is providing power to the socket.
- Dim or Flickering Light: Check for loose connections or corrosion in the socket. Ensure the vehicle's voltage is within the operating range of 9-30 VDC.
