Included is a pair of front turn signal bulbs which are "switchback," a unique and very special design. When this bulb is in its normal on position with your parking lights or headlights, it shines a nice, pure white color. But when you activate your turn signals, it flashes bright amber. Offering you two colors in one bulb, for an awesome lighting effect! You will also receive a pair of cool white LED bulbs to replace your factory front sidemarker bulbs. These bulbs are specially designed to distribute light fully in your housing, for a uniform, full appearance and will match perfectly with the included switchbacks.

Due to the circuit design found in the 2015-2017 Mustang, you do not need resistors to slow down blinking speed. Your indicator in the dash will blink at a different rate, but your exterior turn signals will always blink at the standard speed.

Thanks to these unique tri-bar LED headlights, when you see one coming down the road, there's no doubt you're looking at a 2015 Mustang. Unfortunately, in my opinion, the amber mark lights still take away from the look. Ford finally gave us a clear marker light, which looks great on this car, but since an amber light is required for the turn signal, sticking a white LED in there really isn't an option. Thankfully, due to today's technology and LED lighting, you can have the best of both worlds, a white marker light and an amber turn signal.

Today we're going to show you how to install an LED switchback marker light kit, using out 2015 EcoBoost Mustang. This is a switchback LED marker light kit. It's going to include four bulbs, as there are two per side. The larger bulb does your turn signal and marker light and this is the additional marker light here. The beauty with these, is they use an aluminum heat-sink, want to put a much brighter LED so you get a really bright light, but as you can see, you have both amber and your clear, which is what makes it legal. This second bulb here, the design of this LED is going to disperse light really brightly, give it a nice, even look within the marker light lens.

To access the marker light assembly, what you'll want to do is remove the three clips here that hold the splash shield in place. Once we do that, we can actually push the splash shield aside and reach in and grab the bulbs. The only tool needed for this installation is a small screw driver or a small pick. You don't have to put the car up in the air, either, you can easily do this on the ground. I only put it up in the air so you can see it better.

The two we're going to be removing are this gray plug right here and this brown plug here. We'll start with the gray one. Just get a grip on it and turn it counterclockwise and pull out to see the bulb. Just get a grip on the bulb, pull it straight out. Now we'll grab our LED. We'll plug the LED in. It will be a tight fit, which is good, you don't want it to short out. Plug it in, put it back in, turn it clockwise, and put it back in place. It doesn't matter which way you put the LED in, it'll work in both directions. Tighten it up, clockwise lock in place.

Same process with the brown one. Get a grip on it, counterclockwise to remove it, and pop out the bulb. When you grab the LED, make sure the contacts are straight and match up with the contacts on the factory bulb before you install it. Then same process, line it up and install. Put it back in the housing and turn it clockwise to tighten it in place. Before you replace all the push-pins you want to check it and make sure everything's working properly. To check it, simply hit "disarm" on your keypad. When you hit "disarm," it lights up the turn signal first along with the marker, and then the whole marker lights up. If installation is correct, reinstall the plastic trim panel and repeat the process on the other side.

One thing we do want to mention, is your turn signal inside your car will click a little bit differently than it did before. These don't use any kind of a resistor so you get a double-click, then a single-click; that is perfectly normal, it's the way these lights work. There is an additional wire harness available if that bothers you, but most people it's not going to bother at all.

The LED switchback marker light kit's a great way to finish off the lighting on the front of our 2015 Mustang. Now the markers match the rest of the lights and the amber turn signals look killer as well, on our car. As I showed you, the installation is very simple, will take you a few minutes per side, to be back on the road in no time.
