SUPER BRIGHT: Each 3157 led bulb is equipped with 22PCS Customized High brightness 2835 SMD chips, 5.5W per bulb, only 1/4 energy consumption of original halogen bulb but 400% brighter, providing White light or Amber Yellow light. Instant-on capability without warm-up time.
DUAL COLOR FUNCTION: This 3157 Switchback LED lights light up cool white for parking lights or daytime running lights (DRL lights) while light up amber yellow for front turn signal lights. B1B series turn signals flashing "amber-white-amber-white" rather than "amber-off-amber-off". The constant white light will stay on, avoiding complete darkness moment when turn signal is blinking and other lights are off.
360 DEGREE CLEAR BEAM: Each 3157 led bulb is designed with a 360° Beam Angle with HD glass lens for stronger lighting. Just plug and play, compatible for both US standard sockets and CK sockets. Fit socket 3157, 3157A, 3157NA, 3357, 3457, 3457A, 4157, etc. Matching great in the assembly. Ideal replacement for your original bulbs
LONG USE: IP68 waterproof and dustproof. The built-in temp control chips help the bulb work at a lower temperature than others, and the upgraded aluminum bulb body ensures faster cooling and longer lifespan up to 40,000 hours. WARM TIP: If the bulb does not light normally when connected, please try to reverse the polarity.
PRECAUTIONS: Most cars require LED resistors installed when switching from halogen turn signal light bulbs to LED to avoid hyper flashing and low wattage issue. The 50w 6ohm load resistors (included in the package) are needed to prevent the turn signal light hyper flash, malfunction or trigger warning message on dashboard. Please fix the resistors on metal surface for better cooling.
