IMPORTANT NOTE

  1. These only work for dual function/filaments bulbs that have both the parking light and turn signal function in one bulb.
  2. 50w 6-ohm load resistor or flasher relay may be needed to prevent hyper flash due to LED bulbs draw much less power than stock incandescent bulbs.
  3. Please check the owners manual, original bulb size or Amazon fitment system before purchasing to confirm if this switchback bulb fits your car
