Feature(may vary by option.)

●Each 3157 switchback bulb powered by 16 pcs high power 3030 led chips, low power consumption but high light output. HD glass lens for stronger light penetration
●The 3157/3156 turn signal 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 )
●9V to 18V wide-range voltage design, built-in constant intelligent IC driver,no digital and VHF radio signal interference. Aluminum circuit board,high effective heat dissipation
●Plug and play easy installation, no polarity design, compatible for both standard and ck socket. Fit socket 3157, 3157A, 3057, 3155, 3157NA, 3357, 3457, 3457A, 4057, 4114, 4157, etc
●Note: These will only work for dual function lights that have both the parking/city light and turn signal function in one bulb. The 50w 6ohm load resistor or flasher relay may be needed to prevent the hyper flash or the bulb does not blink, we have included the resistors in the package in case you need it

Features and Performance Details

  • Each 3157 switchback bulb has 16pcs high power 3030 LED chips for perfect beam pattern, hight light output but low consumption
  • Wide-range voltage and intelligent constant current IC driver to avoid digital and VHF radio signal interference
  • Heat-resistant Aluminum circuit board for better transfer efficiency, solid alloy body for better heat dissipation and longer lifespan
  • Dual function: Light up xenon white for parking lights or daytime running lights, light up amber for turn signal lights
  • The 3157 turn signal 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 )
  • No polarity design, and compatible for both standard and CK 3157 socket, comparable to OEM sized halogen bulbs and fit directly into multiple sockets such as: 3157 3157A 3057 3155 3157NA 3357 3457 3457A 4057 4114 4157 etc

IMPORTANT NOTE

  1. These will only work for dual function lights that have both the parking/city light and turn signal function in one bulb
  2. The 50w 6ohm load resistor or flasher relay may be needed to prevent the hyper flash or the bulb does not blink for some vehicles with sensitive built-in canbus system, we have included the resistors in the package in case you need it.
  3. Pls confirm whether this bulb fits your car before purchasing, if you are not sure, please " ask a question " on product page with your vehicle information
