      Review & Installation Video

      Hey guys, Stephanie with, and this is my overview of the RTR Grille with LED Accent Vent Lights that's available for all 2015 or newer S550 Mustangs. This overview is gonna cover a few topics with the RTR Grille, like the different options with this Grill as well as the install. The install for this one is a simple one. It's a one out of three wrenches but we'll talk more about that later on.The RTR Grille with LED Accent Vent Lighting is gonna be something that an S550 owner should check out if they're looking to do something a little bit different styling wise, or if they're just looking for some of that RTR statement styling. I mentioned some options earlier and I wanted to explain that before I got into any details with the grille. There a few different ways that you can purchase this grille. You can purchase just the upper with the lights, just the lower, or a combo of the upper with the lights and the lower so you match all the way around and complete the package. There's another option too which may be very good news to some of you. You also have the option of purchasing just the lights if you want to. If you've already purchased the RTR Grille without the LED lighting, you can just pick up the lighting and complete the look. This is the same upper grille with accent LED lighting that's included as original equipment on the RTR Mustangs. You can see it's the same three window design and it's gonna eliminate the stock pony that's normally in the grille. Both the upper and lower grilles are complete replacements of the factory grille, not overlays, and they're both actually gonna help increase some airflow to the ride if you compare them to the stock grilles. Getting into the LED accent lighting some more, obviously, there's gonna be lighting around the vent openings and the accent lights are gonna plug into the factory headlight harness. You won't have to cut or splice, but i'll get more into the install later. Plug in the accent lighting into the factory harness means that'll be automatically activated with the daytime running lights. If the car is on, the accent lights will be on. This grille is gonna work with the stock front fascia, so it'll work for the V6, the EcoBoost, and the GT as long as you have the stock frontend. One thing that I did wanna note though, is that the lower grille, just the lower, is not gonna work on cars that have the Adaptive Cruise Control. This is because the control is mounted in the lower grille and the RTR Grille would interfere with it. When it comes to price, it really all depends what you end up looking for. The combo kit of the upper with the lights and the lower grille together is gonna cost pretty close to the $750 mark. If you wanted just the upper grille, that's about $550 by itself and about $200 for just the lower grille. The lights by themselves are gonna cost close with the $300 mark, so it's safe to say that you definitely save a few bucks by purchasing the kit and then if you wanted to purchase just the light, you're gonna be paying a pretty penny for them.The install here isn't easy one. It's a one outta three wrenches in the difficulty meter and the time for the install will change a little bit depending on if you're installing both the upper and the lower grille, or just one or the other. Assuming that you're installing both, I'm going to say that this will take about two hours to complete. You will need to drill in a bit to drill up three mounting holes for the lights in the grille and that's really easy and simple, so nothing you have to worry about. If you want, you can start by getting the RTR grille ready to install. You drill three mounting locations for the accent lights, but RTR has the locations pre-marked for you already. The accent lights are held in by the supplied hardware and then you'll need to mount the control box to the backside of the grille. There's double-sided tape on the back so it just sticks in a place. You will need to remove the front fascia to complete the install. You just want to jack in some stands or lift to elevate the car some. Removing the front fascia isn't hard. There are a lot of clips and some screws that hold it into place. The fascia will then just pop off and you pull the sides near the headlight. Getting the top factory grille out isn't as hard as you might think it is. There's a soft gasket that comes out with the screwdriver, and then you can remove the plastic clips that are along the edge, the new grille will pop into place using the supplied hardware from RTR and then the center bumper soft gasket goes right back in after the new grille. To integrate the lights, you just need to unplug the headlight harness from the back of the headlight, plug the supplied harness into the headlight, and then piggy-back the factory harness on to that. You might need to tuck the harness up into the frame rail to keep it all up and safe, and that's all it's gonna take. Wrapping things up here with the RTR Grille, this is the OE Grille for the RTR Mustang and it comes complete with the LED Accent Lighting around the vents. The lighting is completely plug and play and the accent lights will illuminate when the car and the running lights are active. This is very easy to install.

      Ready To Rock! Add the same exact Upper grille with accent LED lighting and Lower grille that are included as original equipment on the S550 Ford Mustang RTR, designed and developed by Vaughn Gittin Jr., to your very own late model muscle car for an aggressive race inspired appearance.

      LED Accent Lighting. This RTR upper grille is available with the very popular integrated LED Accent Lighting around the vent openings for an impressive head turning appearance. The LED Accent Lights simply plug directly into your Mustang's existing factory headlight harness with no cutting or splicing required. The LEDs are automatically activated in conjunction with your Day Time Running Lights, so they are always on when your Mustang is running. The LED Accent Lights is only compatible with the RTR Upper Grille, it is not designed to be used with factory or other aftermarket grilles. For those that would like the RTR Upper grille without the accent lighting please see part# 389943.

      High Powered SMD Technology. The halo rings included with this RTR upper grille utilize SMD technology to produce a super bright white light while only consuming 1/10th of the power of standard incandescent bulbs. These LED accent lights are rated at 100,000 hours of continuous use.

      Improves Cooling. These RTR grilles not only add aggressive styling to your S550 Mustangs front end, but they also increase air flow to the radiator, when compared to the stock grille, for improved engine cooling and performance.

      Quality Construction. Designed using the original OEM CAD data from Ford to ensure a perfect fit, both the upper and lower RTR grilles are manufactured from an OEM quality high pressure injection molded high-strength thermal plastic olefin (TPO) material for its long lasting durability against the elements and the hazards of daily driving.

      Application. These RTR grilles are designed to fit 2015 to 2017 GT, EcoBoost and V6 Mustangs with the stock front fascia installed. The upper and lower grilles are available separately or in a convenient combo kit (select from choices above).

      Application Note. For those customers who already own the standard RTR grille (part# 389943) a LED Accent Lighting upgrade kit is now available - see the options listed above. The Accent Lighting requires the RTR Upper grille for proper installation.

      Technical Note. The RTR Lower grille is not compatible with Mustangs equipped with the Adaptive Cruise Control (ACC) .

        Very appealing

        Not only does the grille look good but, now there is airflow directly into my intake and noticed some positive temp differences as well. A buddy and I struggled little bit with clipping it in since 1 clip was broken so it took longer than expected.

        Love The RTR Grill But Replacing The Lights

        The RTR Grill and Light really sets off my Pony and turns heads - I fitted them over 18 Months ago and have had no issues until to day. I noticed one of the lights has failed and looking at other reviews on this product it seems to be an issue after time with these LED's I'm now about to order the second set of lights and hope RTR have improved the LED's as they are costly at $300 - Purchasers need to be aware of this.

        Works great.

        These LEDs work fine but they only come on when the car is powered. They won't flicker or anything when interacting with the key fob as the daytime running lights do.

        This grille really makes the s550's pop. I highly recommend this grille if you want to eliminate that ugly pony and give your car a very aggressive look. The install was timing consuming since you had to take off the bumper.

        My favorite mod

        This grille really makes the s550's pop, it looks so good in person, pictures do it no justice. The install wasn't hard but it was a little time consuming taking off the bumper, other than that it was a piece of cake. I highly recommend this grille if you want to eliminate that ugly pony and give your car a very aggressive look, don't buy the knockoff versions.

      i see that you can buy the upper and lower grille and the light for the upper grille, but is there any way you can buy lights for the lower grille also?
