Guía de instalación
Follow these steps to install your Grandview 7443 LED Switchback bulbs. Ensure your vehicle's ignition is off and the lights are cool before beginning installation.
Step 1: Access the Bulb Socket
Locate the existing turn signal bulb housing in your vehicle. This often requires accessing the area behind the wheel well liner or from under the hood, depending on your vehicle model.

Step 2: Remove the Old Bulb
Gently twist the bulb socket counter-clockwise to unlock it, then pull it out from the housing. Remove the old incandescent bulb by pulling it straight out from the socket.

Step 3: Insert the New LED Bulb
Insert the new Grandview LED bulb into the socket. Ensure it is fully seated.

Step 4: Test Polarity (If Necessary)
If the bulb does not light up, remove it, flip it horizontally (180 degrees), and reinsert it. LED bulbs are polarity sensitive and may only work in one orientation.

Step 5: Secure the Bulb
Once the bulb lights up correctly, reinsert the socket into the housing and twist clockwise to lock it securely in place.

Instrucciones de funcionamiento
These bulbs feature a dual-color switchback function:
- When your parking lights or daytime running lights (DRL) are on, the bulbs will illuminate in a bright white (6500-8000K) color.
- When the turn signal is activated, the bulbs will switch to a vibrant amber color, flashing to indicate your turn. Once the turn signal is deactivated, they will revert to white.

Cuidado y mantenimiento
- Keep the bulbs clean and free from dirt or debris. Use a soft, dry cloth for cleaning.
- Avoid touching the LED chips directly with bare hands to prevent oil transfer.
- Ensure proper ventilation around the bulb housing to prevent overheating, which can shorten LED lifespan.
Solución de problemas comunes
Hyper Flashing (Rapid Blinking)
If your turn signals blink rapidly after installing LED bulbs (known as "hyper flashing"), this indicates that your vehicle's flasher relay detects a lower power draw from the LEDs compared to incandescent bulbs.
Solución: While these LED bulbs are designed to be compatible with most vehicles, if hyper flashing occurs, you may need to install external load resistors (not included with this specific product) or a compatible LED flasher relay. Consult a professional if you are unsure.
La bombilla no se enciende
Check the polarity. LED bulbs are polarity sensitive. Remove the bulb, flip it 180 degrees, and reinsert it. Ensure the bulb is fully seated in the socket and the socket is securely locked into the housing. Verify that your vehicle's electrical system is providing power to the socket.
Error Messages on Dashboard
Some vehicles may display a "bulb out" warning or error message due to the lower power consumption of LEDs. This is similar to hyper flashing and may require load resistors or a CANBUS-compatible LED flasher relay to resolve.
