    Review & Install Video

    Switchback LED Bulbs. By simply installing a "Switchback" LED Turn Signal Conversion Kit you will improve the exterior lighting and appearance of your S550 Mustang. This conversion kit replaces those weak incandescent stock amber bulbs with super bright dual-color LEDs for a unique custom look. The dual-color feature allows you to use the white LEDs for the running/parking lights, but when you activate your turn signals or hazard lights the LEDs change to amber like magic.

    Kit Includes. This LED Turn Signal Conversion Kit comes complete and includes a pair of two "Switchback" front turn signal bulbs and a pair of two white front side marker bulbs.

    Plug-and-Play Installation. Installation of the Switchback Turn Signal Conversion Kit is 100% plug-and-play. There is no cutting, splicing or resistors required, just replace your factory incandescent bulbs with the ones in the kit. It's that easy!

    Note About Operation. Seeing that Ford redesigned the circuitry of the all new S550 Mustangs, you will not need a resistor to slow the turn signal blinking rate. The exterior turn signals will blink at the same speed as they did before, however the interior dash indicator will blink at a different rate.

    Application. This Switchback Turn Signal Conversion Kit is specifically designed for use on the 2015 to 2017 Ford Mustangs, including the V6, EcoBoost, GT and Shelby GT350 models. Recommended for use with clear turn signal housings.

    Application Note. This Vividline Switchback Kit is designed for Mustangs sold in the US market. They will not function properly on Mustangs sold in the EU or UK.

    I have installed the units bulbs, However when signal is on the turn signal in the interior is faster than normal, usually happens when a indicator dies, Is there a way to rectify faster indicator sound?

    I have been very happy with this kit for my 2015 Mustang! However, one of the WHITE FRONT SIDE MARKER BULBS stopped working and I need to replace it . Where can I buy a replacement bulb? Thanks!

    So I have a 2019 Mustang and I was wondering if anyone knows if there will be this option for 2019 mustangs because it says it's only for 15-17. Thanks

    • At this time, we do not have this switchback kit for the 18 and 19 models.

      Looks great, works great, but...

      Looks great, but the turn signal indicator sound produces an annoying double click that is ment to alert you that you have a turn signal lamp out. If you could get rid of that, I would give it 5 stars.

      1 Year after Installation

      I put these on almost a year ago and they still work great. They took less than an hour to install total. It was slightly hard to get my hand in to make the connections (I did not remove the entire wheel liner only the front portion) but as long as you take your time, push the bulbs all the way in and make sure you reconnect them properly they should work great. They are very bright and it really makes the car look a lot better.

      Awesome Lights

      I really like the switch back turn signals. They are pure white as driving lights and amber when turn signals. Hi visibility and really compliment the Mustang.

      Do not purchase

      I purchased this light kit and one of the bulbs failed in a little over six months. Being LED bulbs they should last quite a long time, NOT in this case. Save you money buy from another maker. Manufacturer has no defective warranty. American Muscle return policy is your standard 30 days.

      Fit is an issue

      I really like the look these switchback lights provide, but connectivity issues came in to play right off the start. Once I found the sweet spot and got the plugs to stay in the factory housings, I thought things were good. However after a few months I noticed one of the lights not working only to find the led bulb resting on the bottom of the light housing. Adjustments were made to the steel tabs to keep the bulb from falling out of the plug, but that caused one of the tabs to break off. I'd like to know if any improvements have been made to this product, or if there is a better option? I'm sold on the look this product provides, but need something that will stay connected!

      Not so hot

      I’m on my second set so far and looking for a different brand to replace these ones, here’s why after I installed the first set then two months later the left light started flickering while it was just sitting there in idle with motor running. The second set does not blink properly when I use the right blinker, it blinks rapidly compared to the left side even after I tried re-pulling bulb to check connections. It is a hassle to return to AM cause I only had two choices ,,, buy another set of bulbs at $80 then wait for them to arrive then ship old ones back or send in old ones then put old bulbs back into car until new ones arrived which I do not have old bulbs so I had to use option 1. Other than that, if the bulb work right they look badass on car.

      Disappointed

      1st off, props to American Muscle and customer service. Had issue with one side not working about a year in, no questions asked, new set shipped out immediately. My problem was keeping the lights inserted into the plugs. Nothing more aggravating than getting pulled over for signal not working to find out it came out of the plug. Was lucky enough not needing to spend to much time fishing it out of the lens but after a few weeks having to do it again and then again a few weeks later. I put my stock ones back in. Poor design. Too bad because they look great when they did work. What a waste of money.

      Not worth the price

      I have had these about 16 months now. 1st issue. Color match of the front side marker to the turn signal bulb, one is a cooler color, or more blue. Would expect a closer match from the same manufacturer. 2nd issue--one bulb fell out of the socket, maybe it wasn't installed well maybe it is too heavy of an item. 3rd issue-- the front running light is now flickering almost always, thought it was loose, double checked that, just a bad bulb. Any one issue i could deal with, all three makes me feel like i bought some cheap generic stuff.

      loved these ... at first

      Well I didn't do the initial installation on these so there are a couple unknowns with how my installer accomplished something that didn't even fit properly into the stock plug. Everything was great at first, working as they should, and then I went over a speed bump and BOOM the light fell out. WTH? My passenger light popped right out??? So I took it upon myself to take a look to see what happened. First off getting the light out of the box was next to impossible but once I did I tried to put the light back into the plug. IT DIDN'T FIT. WTH??? doesn't fit??? it just falls right out and didn't click into place. So went to ford and ordered a new plug housing. After it came in i opened up the box and tried to plug the light into it. Same thing happened. So either they sell a faulty product or ford made some of their plugs slightly different on some models. This is inexcusable for the cost of this light. In short I ended up completely taking this out and going to DDM tuning and getting the same product for a fraction of the price. And guess what... IT FIT. BAD product. stay away.
