Types of LED Devil Eyes
A LED devil eye is a specialized automotive lighting accessory designed to give vehicles an aggressive, menacing appearance. Typically installed in the headlight assembly, devil eye headlights create a distinctive visual signature that sets your vehicle apart from others on the road. These lighting elements utilize high-intensity LEDs for exceptional brightness and longevity.
Expert Tip: LED devil eyes are primarily for aesthetic purposes and should complement your existing headlight system rather than replace your primary lighting. Always ensure your modifications comply with local traffic regulations.
Colors & RGB Options
While the classic red color creates the most authentic "devil eye" appearance, modern LED systems offer numerous color options:
- Red - Traditional, aggressive look
- Blue - Cool, tech-forward appearance
- Green - Unique, attention-grabbing option
- White - Clean, modern aesthetic
- RGB Demon Eyes - Programmable color-changing options with remote control functionality
Size & Dimensions
Devil eyes come in various diameter options to fit different headlight housings:
- 70mm - Compact cars and smaller headlight assemblies
- 80mm - Mid-size vehicles, most common size
- 90mm - Larger vehicles and custom applications
- Custom sizes - Available for specialized applications
Installation Types
Two primary installation methods exist:
Projector Headlights: Demon eyes projector installations fit inside the projector housing, creating a focused, precise light pattern with superior visual impact.
Reflector Headlights: More affordable and easier to install, but with less focused light output and potentially less dramatic visual effect.
Installation Type Comparison
Compatibility Considerations
When selecting LED devil eyes, verify compatibility with your vehicle's:
- Headlight assembly type and model
- Vehicle make, model, and year
- Electrical system specifications
Model-specific devil eyes offer easier installation and more reliable fitment.
Integrated vs. Standalone
Integrated Devil Eyes: Built into the headlight assembly design, offering a seamless, factory-quality appearance.
Standalone Devil Eyes: Separate components for aftermarket installation in headlights without built-in devil eye features.

Installation Process
-
Preparation and Access
Disconnect the vehicle's battery to prevent electrical accidents. Remove the necessary components to access the headlight assembly, which may include the front grille, bumper cover, and related trim pieces. Carefully label and organize all hardware for reassembly.
-
Headlight Removal
Disconnect the electrical connectors from the headlight assembly. Remove the mounting bolts/screws securing the headlight to the vehicle. Carefully extract the headlight assembly without damaging surrounding components or paint.
-
Headlight Disassembly
Most headlights are sealed with adhesive or silicone. Heat the perimeter of the headlight with a heat gun on low setting to soften the sealant. Carefully separate the lens from the housing, typically by prying gently at designated points. Work slowly to avoid cracking the lens.
-
Old Devil Eye Removal (if applicable)
If replacing existing devil eyes, carefully disconnect and remove them, noting the wiring connections and mounting locations. Use a heat gun to soften any adhesive for clean removal.
-
New Devil Eye Installation
Test-fit the new LED devil eyes in the desired position. For projector headlights, install inside the projector housing. For reflector headlights, position for optimal visibility and effect. Secure with appropriate adhesive or mounting hardware.
-
Wiring Connection
Connect the LED devil eyes to the vehicle's electrical system according to the kit instructions. This typically involves tapping into the parking light circuit or connecting to an auxiliary power source. Use high-quality wire connectors and insulate all connections with electrical tape or heat-shrink tubing.
-
Headlight Reassembly
Once wiring is complete and secured, reassemble the headlight housing. Apply a thin bead of silicone sealant around the perimeter and carefully rejoin the lens to the housing. Ensure proper alignment and even pressure during reassembly.
-
Installation Testing
Before fully reinstalling the headlight assembly, temporarily reconnect the battery and test the LED devil eyes to confirm proper operation. Check for correct alignment, color, and brightness.
-
Final Assembly
Once testing confirms proper function, reinstall the headlight assembly in the vehicle. Reconnect all electrical connectors and secure with the original mounting hardware. Reinstall the front bumper, grille, and trim pieces in reverse order of removal.
-
Final Adjustments
With everything reassembled, make any necessary adjustments to the devil eye positioning for optimal visual effect. Check all lighting functions to ensure proper operation.
Installation Tip: For vehicles with complex headlight assemblies or limited access, consider having a professional handle the disassembly and reassembly process. You can still perform the actual devil eye installation yourself, saving on labor costs while minimizing the risk of damaging expensive components.
Questions and Answers
LED devil eyes and angel eyes serve similar aesthetic purposes but differ in their positioning and visual effect:
- Devil Eyes: Typically installed at the bottom of the headlight assembly or inside the projector housing. They're designed to create a menacing, aggressive appearance with a predominantly red or amber glow.
- Angel Eyes: Installed as halo rings surrounding the headlight or projector lens. They create a more elegant, premium appearance and are commonly found in luxury vehicles. Angel eyes typically use white or blue-white illumination.
While devil eyes aim to give vehicles an aggressive, sport-inspired look, angel eyes tend to convey a more sophisticated, premium aesthetic.
Quality LED devil eyes have an impressive operational lifespan compared to traditional lighting technologies:
- Average Lifespan: 30,000 to 50,000 hours of operation
- Real-World Expectancy: 5-10 years of normal use
Several factors can affect the actual lifespan of LED devil eyes:
- Usage Patterns: More frequent use shortens overall calendar lifespan
- Heat Management: Proper heat dissipation extends LED life
- Voltage Regulation: Stable power supply prevents premature failure
- Environmental Exposure: Protection from extreme temperatures and moisture extends longevity
- Quality of Components: Premium LEDs and circuit boards last significantly longer than budget alternatives
Implementing these maintenance practices will significantly extend the life of your LED devil eyes:
- Regular Cleaning: Keep lenses clean with microfiber cloths and specialized automotive lens cleaners. Remove dust, dirt, and road grime that can reduce light output and trap heat.
- Electrical System Care: Ensure your vehicle's electrical system provides stable voltage. Consider a voltage regulator if experiencing fluctuations that could damage LEDs.
- Proper Cooling: Ensure ventilation openings remain clear and functioning. Some high-performance devil eyes include cooling mechanisms that should be maintained.
- Chemical Protection: Avoid exposing LED devil eyes to harsh chemicals, gasoline, oil, or aggressive cleaning solvents that can degrade lens materials and housing.
- Moisture Prevention: Regularly inspect for and address any moisture buildup inside housings. If detected, open the assembly to dry completely before resealing with appropriate silicone sealant.
- Corrosion Prevention: Inspect and clean electrical connections periodically to prevent corrosion, especially in coastal or high-humidity environments.
- Professional Inspection: Have a professional check the installation annually, particularly if experiencing any performance issues like dimming or flickering.
Following these maintenance practices can potentially double the effective lifespan of your LED devil eyes while maintaining optimal brightness and color consistency.
The legality of LED devil eyes varies significantly by jurisdiction:
- Many regions prohibit red or blue forward-facing lights (common devil eye colors)
- Some areas restrict aftermarket lighting modifications entirely
- Regulations may differ for "show use" versus "street use"
Always research local traffic laws before installation. In many cases, amber, white, or yellow devil eyes are more likely to be street-legal than red or blue versions. Some enthusiasts install color-changing models that can be switched to legal colors for street driving.
