A couple weeks ago I showed you how to install headlights, taillights and a roof mounted light bar on your Yeti SCORE Retro Trophy Truck body. It was a pretty simple process – but what if you have a standard Yeti SCORE Trophy Truck body? Well, thankfully the procedure is the same with just a few minor tweaks.

You’ll need a few tools to complete this job, listed here:

Tools
1. Body reamer or something similar to enlarge the holes in the plastic headlight/taillight parts.
2. Shoo Goo or something similar to secure the LEDs in place.
3. Hobby Knife.
4. Silver Sharpie. Optional, but great for that extra detail.
5. Tape. Black for securing wires to the cage, clear for securing wires to the inside of the body.
6. Y-connector for combining the front and rear light strings into one.
7. 6″ (or longer) servo lead extension.

I’ve also included all the Axial parts needed at the bottom of the article.

Let’s get started!

Step 1

Adding Lights to the Axial Yeti SCORE Trophy Truck
The first step will be to remove and modify the front and rear light buckets to accept a pair of LEDs a piece. The front bucket has only 1 hole – the left red arrow shows where you can ream out the hole to add a 2nd LED. Ream only a little at a time, test fitting the LED until it pushes in nice and snug. The rear bucket (on the right) has two holes, but you’ll need to make the lower one a little bigger to accept the larger LED. Again, open the hole a little at a time until the LED sits nice and snug.

I added a little detail to the front light buckets using a silver Sharpie. It’s not necessary by any means, but I do like the way it highlights the all-black buckets.

Step 2

Adding Lights to the Axial Yeti SCORE Trophy Truck  Re-install the front light buckets to the body and press the LEDs in place. Use a dab of Shoo Goo to hold the LEDs in place, letting it dry thoroughly. Route the wires as needed using clear tape to hold them down. Try to keep them in the raised sections of the body so the tires won’t hit them when traveling through rough, rocky terrain. I’ve also installed one of the 3-Port High-Output LED Controllers on the front hood. Route the left and right headlight strings over and plug them into the side-by-side plugs.

Step 3

Using the same procedure as we used for the front, install the buckets and LEDs to the rear of the TT.

Step 4

Adding Lights to the Axial Yeti SCORE Trophy Truck
Run the LED power wires along the rear cage as shown, using the black tape to hold them in place. If you want to do a super trick, feed the wires through some black shrink tubing prior to attaching them.

Step 5

Adding Lights to the Axial Yeti SCORE Trophy Truck
The 2nd 3-Port High-Output LED Controller is mounted to the underside of the roof. Route the left and right taillight strings along the cage and plug them into the side-by-side plugs in the controller. I would suggest mounting the controller so that side-by-side plugs face the rear; if you decide to install a roof-mounted lightbar, it can plug into the single high-output plug facing the front.

Step 6

Adding Lights to the Axial Yeti SCORE Trophy Truck
Take both leads from the 3-Port High-Output Controllers and run them to either side of the TT body, using the clear tape to keep them in place. You may notice that the leads use 2 wires (and a mini-JST plug) while the Y-connector uses a 3-wire plug. That’s OK - just make sure that when you connect them, the black wire mates up to the black wire (or in this case, the brown wire).

Step 7

Adding Lights to the Axial Yeti SCORE Trophy Truck
Flip your TT over and remove the little hatch on the bottom of the chassis. This reveals the receiver we’ll need to plug the light string into. Pop the receiver off the tape and pull it out slightly, like the picture. You’ll also, at this time, want to remove the top black spacer in the clear silicone plug (the spacer is shown just to the left of the receiver box). Now, carefully feed your 6″ extension from the topside of the truck down to the receiver box. It’s a little tricky and you might have to push some other wires out of the way, but it is possible – and I suggest doing it from the top down.

Once you have it through, plug the 6″ extension into port #3, making sure the black wire (or brown wire) is facing the same way as the black wires already installed. Now, press the extension wire into the clear silicone plug, taking up the space of the black spacer you removed earlier.

Step 8

Adding Lights to the Axial Yeti SCORE Trophy Truck
Flip the truck over and you should have about this much of the 6″ extension left sticking out. Adjust how much of the extension is left (if necessary), flip the TT back over and press the receiver back into the box. Coil up any excess extension wire, push it into the receiver box and re-install the receiver box door.

Step 9

Adding Lights to the Axial Yeti SCORE Trophy Truck
Set the driver interior back into place, mate the Y-connector on the body to the 6″ extension and re-install the body.

Our SCORE Trophy Truck body is now ready for some night time driving. Plug the battery in, flip the switch on and check out your fantastic work! Here’s an example of how it should look when you’re finished:

Did you know that the Axial Yeti SCORE Trophy Truck comes pre-configured for LED lighting? Yup, that’s right, all you have to do is attain and install the LEDs, route the wiring to the receiver and enjoy some brightly lit evening drives.

In this article, I’ll take you through the step-by-step process of installing a full set of LEDs in the front and rear buckets as well as adding an Axial Universal Rigid Light Bar Set. In addition to all the lighting components (listed at the end of the article), you’ll also need a few other tools to make the installation easy.

Tools
1. Body reamer or something similar to enlarge the holes in the plastic headlight/taillight parts and for making holes in the body.
2. Shoo Goo or something similar to secure the LEDs in place.
3. Hobby Knife.
4. Silver Sharpie. Optional, but great for that extra detail.
5. Tape. Black for securing wires to the cage, clear for securing wires to the inside of the body.
6. Y-connector for combining the front and rear light strings into one.
7. 6″ (or longer) servo lead extension.

Step 1

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Before installing the LEDs in the light buckets, there is a little bit of prep work that needs to be done first. The buckets have provisions for 2 LEDs; 1 standard headlight and one smaller turn signal. Since I wanted to have both sockets use the super bright LEDs (for a headlight and driving/fog light), I had to use the reamer to open the hole up in the smaller socket to fit the larger LED. Widen the hole in small increments, test fitting the LED a couple times until the fit is nice and snug.

For some added detail, I highlighted the area with a silver Sharpie. I think it turned out pretty cool looking and having it mounted behind the Lexan body helps protect it.

Step 2

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Once you have the front buckets mounted, press fit the LEDs into the them. We have two solutions to securing the LEDs; you can use the supplied cap and screw (left LED) or Shoo Goo (right LED). Either method works great but since I didn’t have enough of the small 2-56 screws to complete the project, I opted for Shoo Goo.

Step 3

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Using the same procedure, install the buckets and LEDs on the rear of the Retro TT body. You’ll need to ream out the smaller hole in this bucket as well. Since I was using the red tail light stickers on the rear of the Retro body, I opted to use white LEDs. You could also use red ones here instead for more red lighting – I listed the red LED part numbers at the end as well.

Step 4

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Route the rear LED power leads along the rear cage and secure with the black tape. This helps keep the wires away from the spinning tires. If you have some available, you can feed the wires through some shrink tubing for added protection.

Step 5

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Build and mount Axial’s roof-mounted LED bar. A slit can be cut into the roof to pass the wires through. We won’t get into detail about building it – it’s pretty simple. Just take a little extra care to make sure it’s mounted square on the roof.

Step 6

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Flip the Retro TT body over and feed both the front and rear LED power leads into an AX31097 3-Port High Output LED Controller (use double-sided tape to secure the controllers on the body). The roof mounted LED light bar will connect to the high-output port on the rear 3-Port High Output LED Controller. Masterfully tape all the wires down using the clear tape.

Step 7

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Feed the 3-Port High Output LED Controller leads to the side of the body and tape them down using the clear tape. Take your Y-connector and connect them as shown. The LED controller wires use a 2-wire, mini JST plug – our Y-connector has standard 3-wire plug. Just make sure the black wires match up and you’ll be good to go. You can add a little extra tape here to secure any additional wires.

Step 8

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Next, we’ll be installing the 6″ extension, so start by removing the little door on the bottom of your TT to expose the receiver compartment. You may need to ‘pop’ the receiver off of the tape used to secure it to make this a little easier. You’ll also need to remove the little black spacer used in the clear silicone grommet. We’ll be filling that space with the new 6″ wire.

I found it way easier to feed the 6″ extension down to the box from the top of the truck and into the box. Insert the 6″ extension plug into your receiver with the negative wire (black or brown) towards the outside of the receiver. Press the wire into the clear silicone grommet, making sure it’s down below the top of the grommet.

Step 9

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Turn the truck over and inspect how much of the 6″ extension you have available. This picture shows an adequate amount you’ll need. Flip the TT back over, press the receiver back into place and coil up any additional wire into the receiver box. Replace the receiver box cover.

Step 10

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Install the plastic interior in place, connect the lighting power wires (black to brown in this case) and fit the Retro body to your TT. We’ve left enough slack in the wire to remove the body without having to unplug the wires each time, but if you feel it’s too long you can always shorten the lead by pulling a little more into the receiver box.

And just like that, we’ve got some very bright lights on our Retro bodied TT! Here’s an example of how it should look when you’re finished:
