Demon-Eye LED Kit
Get your Demon-Eye kit running right, the first time.
Everything you need to install, wire, and set up your HaloEye kit — side by side, no dealership required. Plan on roughly 45–90 minutes per headlight.
01 — Getting Ready
Before You Start
Thanks for picking up the HaloEye Demon-Eye LED Kit. This guide walks you through a full install, side by side — just you, a set of basic tools, and a garage. No dealership, no shop bill.
Read this first: Demon-eye lighting is a cosmetic accent — but this kit is also a functional light unit, so treat the wiring step with the same care as any other light install. It's designed to sync with your DRL/parking circuit and automatically step aside when your main headlights (low/high beam) are on, so your real night-driving illumination is never affected. HaloEye kits are intended for show, meet, and off-road/track use — check your local regulations before running any non-stock lighting on public roads.
What's in the Box
| Item | Qty |
|---|---|
| Demon-eye projector lens units (remote-programmable iris display) | 2 |
| LED ring modules | 2 |
| Control module (power & sync box) | 1 |

| 4-button wireless remote (ON/OFF, Eye, Emoticon, Car Logo) | 1 |

Each lens unit is a self-contained programmable display — color, emoticon and logo patterns are selected from the remote, no physical disc-swapping required.
Tools You'll Need
- Phillips & flathead screwdrivers, trim/panel removal tool
- Heat gun or hair dryer (for resealing housings, if your headlight is glued shut)
- Electrical tape or heat-shrink tubing, wire strippers
- Multimeter (optional, but useful for confirming power before you commit wiring)
- Clean microfiber cloth
02 — The Install
Installation, Step by Step
Work one headlight at a time so you always have a finished reference side. Repeat the full sequence on the second unit.
Access the headlight
Remove the headlight assembly (or open your access panel, if your housing has one) following your vehicle's standard headlight-removal process. If the housing is sealed, gently warm the seam before separating the lens.
Locate the projector
Find the main reflector/projector inside the housing — this is where the demon-eye unit will sit.
Mount the lens unit
Fit the demon-eye projector lens over the reflector, centered and facing straight forward, and secure it with the included brackets. Fit the LED ring around the projector (or behind the lens, depending on your kit variant).
Wire to the control module
Connect the lens unit's harness to the control module using the labeled power, ground, and signal connectors. Mount the control module somewhere dry and secure, then connect it to your power source of choice: DRL or parking-light power for always-on daily use, or a dedicated switched 12V line if you'd rather the eyes only come on for meets and shoots.
Pick your mode
Power on and use the wireless remote to choose Eye color, Emoticon, or Car Logo modes. See the full mode guide below.
Seal, test, repeat
Reseal the housing, reinstall the assembly, and power on to confirm the eyes light correctly and your main headlights still work normally. Once confirmed working, repeat steps 1–6 on the other headlight.
03 — The Tech
How It Works
Pro tip: Do a full dry-run test — module connected, remote paired — before you reseal the housing. It's much easier to fix a loose connector on the bench than after everything is closed back up.
Each lens unit is a projector housing built around a small remote-programmable LED display rather than a static bulb, shaping light into a glowing three-dimensional eye that looks bold when lit and subtle when off, and some versions can include a mechanical blink or pupil-rotation effect.
The control module manages timing so the demon-eye effect steps back whenever the main headlights are on, keeping normal road illumination untouched; the same housing can also function as a plain white/yellow beam if the eye display is not being used.
04 — Customization
Choosing Your Mode
The kit ships with 33 total looks split across three families, all switched instantly from the remote — no disassembly and no physical disc-swapping needed.
On/Off
Powers the display on or off without touching your DRL/parking wiring.
Eye
Cycles through 11 realistic iris colors.
Emoticon
Cycles through 8 animated cartoon-face patterns.
Car Logo
Cycles through 14 projected logo patterns.
Eye Colors — 11 Looks
Plus 3 additional accent variations cycled from the same button. Red/black is the HaloEye default at unboxing.
Emoticon Mode — 8 Looks
Car Logo Mode — 14 Looks
Projects 14 rotating brand-logo-style patterns onto the lens. Cycle through them with the Car Logo button on the remote — press and hold to stop on the one you want.
05 — Setup & Support
Wiring Modes
Separate from the remote's display modes above, how you wire the control module decides when the eyes are allowed to turn on at all:
- DRL-linked
- Eyes glow whenever your daytime running lights are active — the most always-on setup.
- Parking-linked
- Eyes activate with the parking lights and switch off during full headlight use.
- Show-only
- Wired to a dedicated switched line so the eyes only come on when wanted — ideal for meets, shoots, and off-road use.
Troubleshooting & FAQ
| Issue | What to check |
|---|---|
| Eyes don't light up | Confirm the control module has a solid ground and is receiving power on the tapped wire; test the circuit with a multimeter before re-checking harness connectors. |
| Flickering | Usually a loose or partially seated connector; reseat every harness connection and add dielectric grease if the install sees rain or heavy wash exposure. |
| One side works, the other doesn't | Re-check the second unit's wiring against the first; it is usually a swapped or unseated connector rather than a faulty part. |
| Eyes stay on with high beams | Double check the unit is wired to DRL/parking and not an always-hot 12V line if you want the auto-dim-with-main-beam behavior. |
| Remote won't switch modes | Confirm the remote and control module are paired, within range, and that the module has solid power; Eye/Emoticon/Car Logo buttons only respond once the unit is powered on. |
| Condensation inside the housing | Make sure the housing is fully resealed with no gaps, and let it sit closed for a few hours before driving in wet conditions. |

Legal & use reminder: Demon-eye lighting is a cosmetic accessory intended for shows, meets, and off-road/private-property use. Laws on supplemental or non-stock lighting vary by state, country, and jurisdiction — check what is allowed before running it on public roads.
