        these ones are shorter then the axial ones. I think it looks better. same housing length just led bar inside is shorter. with a black car the stock reflector is atrocious. I thought about not hooking them up at first but I ended up doing it anyway. matches the side markers I suppose.

        Nice deep tint, bright LEDs

        I bought these open box and they looked fine, no visible damages. I powered them up to confirm they worked and how bright they'll be... A-OK and very bright. Should be a good addition to the 4th brake light and the LED rear side markers. During day time, the tinted markers will look better on my aggressve diffuser. I read the instructions and the other reviews, so no worries going into the install.

        5 2017 GT - Maurice Installation Time: Less than 1 Hour


        Easy install. I used the same idea from another survey by drilling a hole for the wires to go through. Great product. They look great!! I did drop my muffler on passenger side to ease install.

        Diffuser Lights

        The car should’ve came with these stock! Not too bright, not to dark, but definitely adds a nice touch to my pony. Install was super easy I did it on a lift and used shrink wraps instead of the pinch connectors it comes with.

        5 2016 GT - SouthboundMike Installation Time: Afternoon

        Nice product with some install mods

        I always thought the factory red reflectors had to go. I opted to replace them with the smoked LEDs from MP Concepts and they look great! They match my smoked LED side markers perfectly. That said, I threw out the installation instructions. At first, I gave the recommended snap locks and "electrical" tape included in the kit the benefit of the doubt. It took all of 30 seconds to decide to throw them out and do the installation correctly. The first modification I made was to drill a 3/8" hole in the recess for the light for the wiring to pass through...drill 2 1/4 inches from the center of the square clip hole. This allowed the wiring to pass through the bumper cover much cleaner without trying to squeeze it through the clip hole as suggested by the manufacturer. The next thing I decided to do was to strip some insulation away from the factory harness wires and splice the marker light wiring finishing it off with some solder. Finally, I used high quality 3M electrical tape to finish it all off. With the modified installation method, it's a great product.

        5 2015 GT - KenH Installation Time: Less than 1 Hour

        Unique Style

        These were easy to install and only took about 30 minutes to wire up. I didn't like the scotch locks they came with, so I used a high quality, solder/heat shrinked butt connector. Then wrapped with a good 3M electrical tape. They look great on the black plastic trim on my Premium GT. Look great when lit up too. I think I'm the only one in my CandC group to have them?
