      Video Review & Installation

      Hey, guys. Adam here with Today we're taking a quick look at and installing the Axial LED Rear Side Marker Light in red, available for the '99 to '04 Mustang. You should be checking this out if you're looking to swap out the factory rear reflector in favor for something that actually has light functionality like this option from Axial. This is gonna completely replace that side marker light on your rear bumper on both sides and replace it with something that looks pretty OEM when the lights are off, but actually has an LED light strip that's extremely bright when your headlights and tail lights are on. This will wire in right to the factory harness on the backside of your tail light to work in conjunction with your tail light so that it lights up in a really bright, very vibrant LED red.Now, the LEDs there are rated to last a long time, it's an SMD LED technology. It has a red reflective finish on the lens itself, you actually have the option to get it in smoked as well if you're looking for a stealthier look. The red option I have here looks, again, very OEM when the lights are off. But if you want something that also looks aftermarket when the lights are off, smoked is the way to go. This guy regardless has the LED that's so bright, it's gonna definitely grab the attention of people looking at the side profile of your Mustang. Of course, it adds to the appearance, that goes without saying, but it also adds to safety and functionality. You're obviously a lot more noticeable at night with something that actually has a light as opposed to your factory one that just reflects it.Now, the price tag for this comes in right around 50 bucks, making them a really impactful and very affordable mod. And the install is gonna get two out of three wrenches on our difficulty meter. Now, I'll give it two out of three just because it requires some splicing but there are quick splice connectors included in the kit to make sure that you don't have to do any cutting, no wire stripping, none of that nonsense. It's really just gonna clamp right onto the factory wiring harness on the back of the tail light. With that said, you do have to pop off just the corners of the bumper and I'm gonna show you guys that process just a few preliminary steps before you can actually get to the back of the light. Either way, it'll take you about an hour from start to finish. I'm gonna show you every step of the process here. What do you say we get started?Tools used in this install include an impact gun, extension, ratchet, 10-millimeter and 11-millimeter deep sockets. Phillips head socket is what I used but you can also use a really short Phillips head screwdriver, needlenose pliers, small flathead screwdriver, and a panel removal tool. First up, here we gotta pop our trunk. I'm gonna grab a panel removal tool, I'm gonna remove the trunk latch trim here. There are four Christmas tree clips, I'm gonna use this panel tool, pry up underneath of it just like that and pry out. They are pretty long. There's about four of these on this piece alone. So, grab that off and then make your way down.Now, I'm gonna take this trim panel and set it inside the trunk. Now, for the back trim carpet liner, there's one of these on each side, little flathead screwdriver will help loosen this guy up right behind our tail light. I'm gonna pop that guy off, same thing on the other side. Now we can pop that whole trim liner off and just set it inside the trunk. All right, so now we're looking at our passenger side. You're just gonna repeat this on the driver side as well. You're gonna peel back this side liner, you're gonna expose this nut here holding on the bumper to the fender, and another one on the other side of that gas tank nozzle.Now, you got to get both of those off on both sides to disconnect it. So, I'm gonna grab my extension and my 11-millimeter deep socket and get these guys off. All right. Now, underneath the bumper here, there's one push pin clip holding it to the inner well liner. I'm just gonna get my panel removal tool, pry this guy off. Repeat that on the other side. In the wheel well behind your tire, there are two Phillips head screws. Now, this can be pretty difficult because the tire's in the way. So, you wanna grab a Phillips head that's small enough, I actually have this Phillips head socket that's actually the perfect size to get in here and get just enough leverage to get these guys off. With that, you can peel the bumper back.Now, on the backside of that marker light, there are two 10-millimeter nuts holding it on. They're extremely difficult to see. If you look at these two studs that hold the bumper to the fender, it's directly underneath of that little piece of plastic. Grab your 10-socket and your ratchet and start working those guys off. Now you can pull the reflector out. We have a factory reflector in my right hand and our new Axial LED marker light in my left hand. Now, visually with the lights off, this isn't gonna look too much different. The only real visual difference is that the aftermarket one here is a little bit of a lighter red and you can faintly see LEDs on the inside. When your tail lights are on, that's where the big visual difference comes into play. Your factory one is just a reflector, there's no light built-in, it is literally just red reflector material on the inside.This guy is gonna run in conjunction with your tail lights, so it's actually gonna have a function, it's gonna light up. Visually when the lights are off, not much of a difference when the lights are on, it makes all the difference in the world. This is something that packs a small package but has a huge impact on appearance, and honestly, nighttime safety. Having an actual light in place of a reflector is gonna make a big difference for being able to be noticed, especially when your lights are on.Now, when it comes to the install, because this is a light, it is gonna have some splicing required. We're gonna run that wiring up to the back of our tail lights and we're just gonna splice them right in, pretty simple with the quick splice connectors, we'll get to that in a bit though. It's gonna mount into the same factory location, we're gonna use the same 10-millimeter plastic nuts to hold it in place, run our wiring back to the tail light and keep it moving.First thing I'm gonna do is grab our wiring, I have it all laid out here. You're gonna run the wiring into the two holes where the studs were, that's gonna run straight through. So, you wanna start that on the left, pull that wiring through, take the black wire on the right, pull that one through. Now, with the wiring on the inside, pull it straight through until the wiring is all the way in and mount your light just like that. Now, on the backside, you're going to take that 10-millimeter factory nut and you're gonna thread the wire through the center of that all the way back until the nut is on the stud on the backside. And again, this is not something you can really see, you have to peel the bumper back, it's underneath a bunch of tabs. From there, you're just gonna thread it on and that's gonna help hold on the light. Do the same thing to the other wire, pull the wire through, feed it all the way in. Once those nuts are on the studs, grab your 10-millimeter and tighten them down from the back.So, next, we need to wait for the wiring to get into the trunk. Now, in order to do that, we're gonna go to this very large grommet here, and we're gonna pull that guy off. Okay, so now what we can do, we're gonna poke a hole right in the middle using this really small flathead or whatever you have on hand, you can even use a knife. Poke a hole just big enough to get two of the wires straight through and then it'll lead right into the trunk. So, I'm just gonna, again, use this small flathead just like that. Just use that to pull the wire through. Do that for both of them. So, now what we can do is feed all the wires through, put them into the trunk and put our grommet back on, mount your bumper back in place. Back underneath the bumper, let's grab that plastic pushpin clip and put it back in place, making sure it's lining up with that hole. You may need to press on the bumper in order to get it to line up there. For the two Phillips head screws, again, you might have to push the bumper back in place and then just mount them back into the factory positions.So, now we can look at our tail light harness. We're in the back of the trunk, we have our wiring pulled all the way through. We're gonna disconnect that there and pull it off of the back of the trunk just like that. Now, the tail light harness from the factory has about four colors. We have brown, black, orange, and then a pink and black, kind of, striped one. What we need to separate here is the black and the brown. Those are the ones that we need. Now, on the back of the light that we just installed, we have a black and a green. Black is gonna go to black, green is gonna go to brown, that's your power. You wanna grab the quick splice connectors included in the kit. This is gonna help me make life a whole lot easier. Now, we have a good amount of wires visible here but if you don't, you need to peel back this electrical tape. You wanna isolate enough wire that you have enough to clamp on to. You don't wanna go too close to the connector, but not too far away. This is enough, we're gonna go right in the middle.Grab that quick splice connector, what you're basically going to do isolate the black, insert that black wire into the quick splice connector until it's all the way through. Grab the black wire from the light we just installed and you're gonna insert that in the other end. One of the ends is open, one of the ends is closed. Just gonna go straight in just like that. Now, this metal clip, you're gonna clamp down with some pliers and that's gonna connect the two to make your ground connection. All right. Once you close that, give this wire a tug, shouldn't come free at all. You can take the top and close it up. We're gonna do the exact same thing to the brown wire and the green one from the light we just installed.Perfect, test out your light, repeat on the other side and we can start putting everything back together. All right, easy enough, we can start connecting the wiring harness back into its original position, slide it on that. Now we can bolt the two nuts back onto the studs that hold the bumper to the fender. Now, at this point, you can zip tie back all the excess wiring if you'd like but it's gonna be under the trunk liner anyway. Grab those factory 11-millimeter nuts and thread them back onto those studs holding the bumper to the fender. Grab your impact gunner ratchet extension and 11 deep socket and tighten them down. Now we can pop this back in place. Now you can repeat that exact process on the other side.Once you have that taken care of, you wanna pull the trunk liner back in place and seat it correctly. Grab that thumbscrew, the one that we used our flathead for earlier. You can typically get it all the way down by hand, the flathead can help though. Once you have that taken care of, repeat that on the other side as well. Now we can put the trunk latch trim back in place. Those were held on by Christmas tree clips, which we can now just push back in. All right. From there, you're done. Good to go. That's gonna wrap up my review and install for the Axial LED Rear Side Marker Light in red, available for the '99 to '04 Mustang. Either way, get yours right here at
