DISCLAIMER!!:
In the video for this product we show the white parking lights illuminated and amber blinkers when using the GTR Lighting switchback LED bulbs. However at the time of making this video we did not document how the truck acted with these lights installed and the engine running - the truck changes how the circuitry works entirely. On the LED switchback bulbs the parking light function is white and the blinker function is amber. On the Tundra, with the engine running, the only time the vehicle energizes the dim parking light circuit (white on the switchback bulb) is when the headlights are turned on.
The original amber DRL function uses the bright circuit of the bulb (amber).The original parking light function uses the bright circuit of the bulb also for some reason (amber). When headlights are turned on, the dim function of the bulb is used (white).

Chris goes over the front turn signal options for the 2014-2016 Tundra in detail and then he installs the front turn signals and parking lights on a 2014 Tundra.
