• White for DRL or parking lights; Amber yellow for turn signal lights. The 3157 led turn signal bulbs flashes "amber-off-amber-off" instead of " amber-white-amber-white", much easier to see. ( Most switchback bulbs in the market flash amber-white-amber-white )
• Designed with a wide 9V–18V DC input range and a built-in intelligent constant-current IC driver, this 4157 led turn signal bulb ensures stable operation without causing digital or VHF radio interference. The aluminum circuit board further enhances performance through highly effective heat dissipation.
• Plug-and-play installation with no polarity design ensures a hassle-free setup, compatible with both standard and CK sockets. Fit socket 3157, 3157A, 3057, 3155, 3157NA, 3357, 3457, 3457A, 4057, 4114, 4157, etc
• Note: These 3157 switchback led turn signal bulbs are designed specifically for dual-function lights that combine parking/city light and turn signal functions into a single bulb. A 50W 6-ohm load resistor or an upgraded flasher relay may be required to prevent hyper flash or non-blinking issues. We've included the resistors in the package, so you'll have them on hand if required.

• Identify the socket code — Check your current bulb for socket code (e.g., 3157). Confirm compatibility with AUXITO 3157/4157 bulbs before installation.
• Remove the old bulb — Turn off the vehicle, open the tail light assembly, and carefully remove the existing bulb from the socket.
• Install the new bulb — Insert the AUXITO 3157 switchback LED bulb into the socket, ensuring proper fit. Connect the wiring securely, avoiding polarity issues.
• Test the lights — Turn on the vehicle, activate turn signals and parking lights to verify proper flashing and illumination. Use resistors if hyper-flash occurs.
