    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.

      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.

      Beautiful.... when they work....

      They are amazing and change the look of the car! Big wow factor. Even safety-wise, you see a lot better at night. HOWEVER, they only work for about 6 months, start flickering and die off. I've had them replaced under warranty twice now. It took well over a month both times... Its great but the products life is very short lived.

      Fog/turn lights 2017

      These lights work even better than expected! The brightness is awesome and it gives the car a beautiful modified look. I installed these in about 2 hrs along with fog lights. It's a great idea to do both at the same time

      Waste of money!

      They don’t work. They start to flicker after a few months. Then you’ll need to buy new ones. Waste of money

      Don’t buy

      Waste of money. Outer lights started flickering after 6 months. Just buy Diode Dynamics instead of these cheap lights.

      Go out in about 4 months

      These sure do look cool. For about the 4 months that they work before they go out. They flicker and go out. Buy something better than these

      Please stay away from these lights

      I'll admit I was pretty ignorant to try this product out after reading the reviews and seeing the sub-par rating. Do they look great? Yes. Is it worth the hassle of constantly replacing the lights? No. These lights are extremely underwhelming. I'm on my third set in 3 months. This will be my last set before I upgrade the quality is so poor for the premium price they are charging. In the long run I wasted money on these but it was a learning experience so before you make this purchase please know you have been warned.

      Great When They Work

      I have had these installed for less than a year. My car was not driven through winter and has been well maintained. These lights have now started to flicker or go out completely. I've pulled them on two occasions, checked connections and reinstalled hoping they were lose or corroded. Nope. They're just junk. I called about a warranty or exchange option but none is available. Now to find a different brand or go back to stock...

      Disposable bulbs

      Takes seconds to install and they do look amazing, completely change the look of the car. They look so good I don't think anyone would want to go back to stock, however, they only lasts a couple of months. I just ordered my 3rd set and I've only had my car 11 months.

      Not good quality

      I have bought these twice thinking maybe the first set was from a bad batch. Only lasted about 2 months before they went out again. I expected better quality from this manufacture.

      Amazing LED's

      This should be a product that every S550 owner should buy. The LED's give a way cleaner and more premium look than the stock bulbs from Ford. Install was insanely easy and took less than 15 minutes for both bulbs.
