Review & Install Video

Hey guys, Stephanie with americanmuscle.com here with a quick overview of the Raxiom reverse light LED that also functions as a fourth brake light conversion kit, available for all 2015 and up S550 Mustangs. This reverse LED light that also functions as a fourth brake light is really going to be something that anyone looking to upgrade their exterior lighting should check out. The S550 still came with standard exterior lighting. Ford didn't equip these cars with LED lighting all the way around, and I know that a lot of guys out there are right there with me when I say that upgrading the LED lighting looks much better. This is the entire thing right here. You have a plug and play wiring harness and the switchback bulb itself, and what this does is simple. First and most simply, it's going to upgrade your normal reverse light to a bright white LED light. This is much brighter than your factory reverse light. The other thing that this does is function as a switchback LED. When you aren't in reverse and you have your headlights or parking lights on, this will switch back to a red running light, and when you step on your brakes, this'll light up as another brake light. So in order for this to act as both a running light and a brake light, it's just going to change in brightness. When it's acting as a running light, it's going to be at 50% brightness, and when you step on the brake, it's going to change to 100% red, so it'll be brighter and have more visibility. Like I said earlier, this is a really simple mod, but adding some LED lighting to your exterior does go a long way for the S550. Since this is a simple mod, it has a simple design and that means a simple install as well, but we'll get more into that in a minute. What you really need to know is that this is a direct fit replacement for your factory bulb. It has an aluminum housing, which means that it'll dissipate heat quickly. This plug right here just plugs right into the stock wiring harness. One thing that I did want to mention just to cover everything is that this is only going to work on U.S. models. If you've got a U.S. V6, EcoBoost, GT or even a GT350, this will work for you. When it comes to price, you can expect to spend between $50 and $100 for this conversion kit. LED lighting isn't really all that expensive for these cars, especially considering that this is a plug and play design that's very easy to install and it makes an impact on your exterior styling. As far as the install, it is very simple. You just need to get to the factory tail light connector, so you'll have to remove the plastic liner in the trunk to get to the connector. The factory connector just unclips and you clip in the Raxiom harness to both sides. This installs right in line and it isn't going to affect your tail light function. There will be one red wire that will need to be ran outside the car, but that just pushes through the existing grommet at the bottom of the trunk and you run it to the connector for the reverse light. This wire will need to be pushed into the connector after you remove the factory bulb. Lastly, it's just a matter of plugging in your new bulb and getting your bulb holder back into place. Wrapping things up here, this Raxiom conversion kit will convert your reverse light to a bright white LED light and it also functions as a switchback light, so it'll also act as a fourth brake light and a running light. It's a direct replacement and it has a plug and play design, which makes for a very easy install. As always, you can check it out more online right here at americanmuscle.com.

Three Bulbs in One. The Reverse Light LED / 4th Brake Light Conversion Kit is really three bulbs in one. This conversion kit replaces the weak incandescent stock reverse bulb with a super bright dual-color Switchback LED. When in reverse the LED shines bright white for maximum light output. With the headlights or parking lights on the bulb activates the red LEDs at 50% brightness to act as a supplementary running light. When the brakes are applied the LED turns 100% red acting as a fourth brake light for greater visibility. This one simple little mod is a quick and easy way to improve the exterior lighting and appearance of your 2015-2018 S550 Mustang.

Quality Construction. The Reverse Light LED / 4th Brake Light Conversion Kit is assembled from state of the art electronic components with a simple plug-in connector that easily inserts into the stock tail light wiring harness. The Switchback LED Bulb is a direct fit replacement for your factory incandescent bulb and features an aluminum housing that acts as a heat sink to quickly dissipate unwanted heat.

Plug-and-Play Installation. Installation of the Reverse Light LED / 4th Brake Light Conversion Kit is 100% plug-and-play. There is no cutting, splicing or resistors required, just plug in the included harness and replace your factory incandescent bulb with the one in the kit. It's that easy!

Application. This Reverse Light LED / 4th Brake Light Module Conversion Kit is specifically designed for use on the 2015 to 2018 Ford Mustangs, including the V6, EcoBoost, GT and Shelby GT350 models. Compatible with US models only - not compatible with EU/AU Mustangs.

Will this also work with the Raxiom tali light sequencer I have installed? Do they plug into the same locations or different? And finally will it work on a Mustang made for Canada? Thanks Dale

  • This third brake light will work the Raxiom sequential kits. It will simply plug into the stock location of the old one. This will also fit a Canadian model Mustang.

  • The Raxiom Reverse Light LED / 4th Brake Light Conversion Kit will light up when the brake is applied with the lights on or off. This will also light with the headlights or parking lights on and act as a running light.

The red running light doesn't increase in brightness/intensity when I brake. Reverse works fine. I have checked the circuit resistance, and ensured I installed everything correctly. Could I have a defective bulb?

    Great add

    To everyone who loves mustangs and wants a little bit of originality changing the reverse light that does nothing to this is definitely a nice add. It gives a nice style to the back of the car and also provides an extra shine to the person behind you so they can stop. Other than just being a light, the install was pretty good. Although i do notice it does have a little lag compared to the main brake lights hardly noticeable, but i notice it when unlocking my car. Still gives it a nice touch and doesn't disappoint.

    Great add-on!

    This light kit works and looks great! The one and only thing that requires patience to complete is getting the red wired connector pushed in far enough in the existing backup module to make the final connection. Using a pair of needle nose pliers... as the last step... grab the wire at the base of the metal connector and press firmly to seat into the module. That's it! Have had great compliments and a couple of buddies took pictures while on a cruise so I could see it in action! LOL!

    Almost Perfect

    I would have loved to give this a 5 star review but I just cant. I gave it three because of some quality control and instruction issues. With that said, if you want this, buy it. Once installed it works great! So why the negative? First, installation should have only taken about 15 to 20 minutes at most. It took me a bit over an hour for one reason. Mostly this is plug and play. Remove some stuff to access the lights, unplug some stuff, plug in new stuff. Simple enough. Then you need to fish a wire from the trunk interior through a grommet to the reverse light. Also simple. On the end of the red wire is a metal piece that is inserted into the reverse light connector. Here is why my installation took so long. The metal piece was not soldered onto the wire. It wasn't even crimped to the wire. When I picked it up, the metal part came off in my hand. So, installation stops so I can drag out my soldering stuff to the car. Problem solved but I shouldn't have had to do it. Yes, I could have just returned it for another but fixing it was easier. Issue #2 is a small lack of instruction in the included guide. The metal piece on the end of the wire has to be installed in the factory reverse light plug. The metal piece is a hollow square tube with a cutout on one side. If you look in the hole in the plug, you can see there is a tab that you must line up with the cutout so it will snap into place. The instruction sheet says to just insert the metal piece into the hole until it clicks in place. But if you don't align it properly, it will never click in properly. I used the little screw driver that was included to seat it in place. Bottom line, it works great! check the metal connector on the red wire before you start. And make sure you check the factory connector so you can align the tab with the cutout in the metal connector on the red wire.

    Raxiom Reverse Light LED ? 4th Brake Light

    Awesome 4th brake light, sure turns heads. Easy to install, did it laying on garage floor. Had small problem inserting the red wire terminal. After assembling the light bulb and installing the assembly into the socket we used the supplied screw driver to further insert the red wire terminal. AL75

    Great safety bonus but could be brighter

    Making the inline connection on the left side took about two minutes. The right side a little longer as I had to remove the Shaker subwoofer from the bracket. With this out of the way, there is enough room to reach the taillight connector without having to remove the entire bracket. Look and function great. Only wish the reverse bulb was brighter. I don't see too much difference between this and stock bulb lumen level. Feel the fourth brake light is a big safety bonus and have noticed a couple double takes from other Stang owners.

    Installation

    Simple unplug and replug on tail lights. If you have the Shaker 1000, the sub will have to be moved to get to the passenger side plug, 2 bolts and 4 screws. I would first run the red wire that goes into the back of the reverse light plug. That is a little tricky, if you don't get it pushed in until it clicks, it could fall out. Install time is about an hour. It works great and nice and bright with the LED's

    Nice look

    While I think the 4th brake light kit looks good and is useful, I gave it only 4 stars simply because I think there is a bit of room for improvement. 1st, the wire that must be routed via the grommet opening on the bottom of the trunk. I think it could be implemented better. It just seems that it leave too much of an opportunity for the wire to get caught on something and get yanked. 2nd, the replacement LED lamp is much longer than the stock lamp so it gets kind of close to the interior of the lens. In itself this is not a big issue except that the tip of the lamp does not center on the lens and instead is angled slightly upward. I double checked to be certain that I have the lamp base installed correctly, and still it skews off the horizontal. Took about a half hour to install. The subwoofer (if equipped) must be removed from its mount to install the clip on the RH side but that is no big deal.

    GT350 4th Brake Light

    The kit is easy to install with the plug and play on the harness inside the trunk. The wire to the bulb socket you have to remover the air diffuser underneath to gain access on the GT350. You will need panel pliers, 13mm socket and access under the car be it lift or jack and stands. The instructions are good and videos on web. I used zip ties to secure the wires inside the trunk. Don't loose the little screw driver as it is a big help on installing the wire in the socket. It takes one person about an hour, The backup light is much brighter. An easy install for a cool product.

    Raxiom Reverse Light LED / 4th Brake Light Conversion

    Pretty simple as it indicates, plug and play. The only hard part is that Ford may not have given you enough wire to play with when you remove the "bulb" to get the wiring harness when installing the red wire. Watch the video on an install first, easier than the directions. If you have a lift, or jack stands use it, much easier to move around under the bumper area to see when hooking everything up. LED is definitely the way to go!
