You can use these LEDs as rock lights, under hood lights (engine bay lights), interior lights, reverse lights and so much more. The Cyclone LEDs under hood lights can be purchased as a stand-alone light, or as a complete kit with single or dual light options.
KC HiLiTES make complete rock light kits for JKs but not for the 4Runner. If you want to use these lights as rock lights on your 4Runner, you can either order the JK kit and buy new mounting hardware, or piece it together on your own.
You also have plenty of options for colors. KC HiLiTES offers the Cyclones in clear, clear-diffused, green, blue, red, or amber.

The 5W LED accessory light kit includes wiring, waterproof switch and one or two Cyclone LED lights, depending on the application. KC HiLiTES makes it easy to add extra utility lighting on your vehicle wherever you want.
The Cyclone offers a versatile flood light pattern and each 2.2” diameter light features 12 LEDs at 5W boasting 1100 lumens, and 516 Raw lumens. In a compact package, these LEDs offer an extremely low amperage draw and high output. KC HiLiTES also offer a 23-year warranty.
The Cyclone LEDs are made from diecast aluminum IP68 (Ingress Protection – a high of 6 is rated for solid material like dust and the 8 is rated for liquids) rated dust and waterproof housing. An IP68 rating is the highest water and dust resistant Ingress Protection rating you will find. To give you an idea, the iPhone 7 has an IP67 rating.
These LEDs can be easily attached anywhere with a Dzus clip or other readily available fasteners that can be purchased directly fromKC HiLiTES. You can also create your own or use the provided hardware in your kit.
The Cyclone LED kit ships ready to wire into any 6 to 16V power source.
Installation – Tool Check
You don’t need much for this install. Basic shop tools will get the job done. Before the install, you may want to grab some extra zip ties and double-sided tape.

Step 1: Disconnect Ground Terminal
Step 2: Run Red/Black Wiring
Start by running your wires through the engine bay weather stripping. There is a small gap that is perfect to run these wires through. You will eventually zip tie the wires to the hood on the driver side.
Step 3: Mounting the Cyclones
Figure out the best location for your 4Runner. Every set up is going to be different. On the 5th Gen 4Runner, I wanted to mount the cyclone LEDs on the lower section of the hood support ribs about 3.5″ down from the center hole.
Step 4: Mark Drill Location
Step 5: 1/8″ Bit – Drill with protective back
Take a 1/8″ drill bit and drill a hole through the hood support rib. Attach the cyclone LEDs using the supplied hardware. To prevent drilling straight through your hood use a strong piece of plastic or wood behind the hood support ribs when drilling. I used a plastic pry tool, this worked pretty well. The plastic pry tools are thin enough to fit between the hood support ribs and strong enough to stop the drill bit and prevent it from going through the hood.
Step 6: Drop washer and screw into Cyclone
Step 7: Screw down Cyclone
Step 8a: Run the wire into the Hood
Route the two red and black wires along the firewall towards the driver side windshield. On the 5th Gen 4Runner, there is an opening in between the black weather stripping and the firewall where you can fit the two pairs of wires.
Route your wires through this opening and start feeding the wires into the hood. Run the short wire up through the hood and let it hang on the driver side and then run the long cable over to the passenger side through the openings in the hood support ribs.
Step 8b: Run the long wire through hood support ribs
Step 9: Mounting the Switch – 1/8″ Drill Bit
Depending on your current wiring set up you will need to locate an area near the battery along the firewall. You will need to drill a 1/8″ hole in the firewall, then screw down the bracket.
Step 10: Mount the Bracket
Install the switch bracket using the supplied screw.
Step 11: Installing the Switch
Start by sliding the toggle switch up through the bracket. Then slide on the ON/OFF cover, then screw down the locking nut.
The directions recommend installing the switch with the wires pointing towards the battery. For my set up with the Xenon Depot HID wiring harness, the wires facing the cabin worked better for me.
Step 12: Rubber Pliers & Rubber Toggle Cover
I didn’t want to take any chance bending or stripping the tiny lock nut that comes with this kit. I used a pair of rubber pliers (soft touch pliers) to tighten the lock nut down. Then, screw down the rubber toggle switch cover. Your switch is ready to go.
Step 13: Double Sided Tape & Mounting the Fuse
You can mount the inline fuse wherever you see fit. I mounted the fuse on the actual fuse box next to the battery. This gave me a perfect amount of positive and negative wiring to connect to the battery.
Step 14: Loose Zip Ties & Plug in Wires
Loosley zip-tie your wires together and connect the Cyclones to the black/red wiring.
Step 15a: Check Wire Fitment & Loom Wires
Once everything is wired up and finished you can use the supplied wiring loom to cover any exposed wires.
Step 15b: Check Wire Fitment on Hood
Open and close your hood a few times to make sure all wires stay in place. I had to adjust the wires a few times to make sure the wires stayed in the exact same place. You dont want the wires too tight but you also dont want the wires hanging down to far to catch on something.
Step 16: Connect Negative & Positive Terminals
Once your Cyclone LED lights are mounted and wired you can then return to the battery where you will attach the black ground wire to the factory ground or on the battery. Then install the red power wire to the power positive side the battery.
Step 17: Flip the Switch!
KC HiLites Cyclone Under Hood LEDs – Final
These lights are seriously impressive. The perfect amount of light. The Cyclones are not too bright and obnoxious. They throw a very smooth floodlight pattern that covers the entire engine bay and some. These shots were taken about an hour after the sun went down.
From pitch black to a completely lit up engine bay in about 30 minutes.
Could not be happier with the results.
