10W Universal LED Puddle Lights for Ground Illumination & Vehicle Entry Safety

Compact 18mm LED puddle lights that deliver 100–300 lumens, operate on 12V DC, and fit universal or OEM mirror/door mounts to improve ground-level visibility for GMC, Ford, Mustang, Lexus, Mini Cooper, Dodge and other models, also called courtesy entry lights or ground illumination lights, designed to project a downward-facing beam beneath the vehicle door or side mirror. 

The featured product from our Auxiliary Lighting Collection — 10W Universal LED Puddle Lights (18mm Pair) — is a compact automotive accessory light built for installation in door panels, side mirrors, or lower door card surfaces.

Each module is a 12V DC-rated LED puck (18 mm form factor) using high-efficiency LED chips with a wide downward flood beam (≈120°–180°) for ground illumination. Typical lumen range across the range is ~100–300 lm per module, depending on color temperature and LED configuration; white options are specified at 5000–6000K for clear visibility, yellow variants at lower Kelvin for glare reduction.

Technical Specifications :

  • Voltage: 12V DC (vehicle accessory circuit)
  • Wattage: ~1–10W per module (product configured at 10W nominal)
  • Polarity: many universal modules are polarity-sensitive — non-polarity versions available for true plug-and-play.
  • Activation (trigger sources): door pin switch, dome light circuit, or keyless-entry unlock signal; aftermarket installs may require a relay to prevent parasitic drain.
  • Mounting: mirror housing recess, door card screw/adhesive, or underside of door panel; vehicle-specific kits provide OEM-style snap fit.
  • Options & variants: plain flood puck, RGB/logo projector variants, and sealed IP-rated housings for exterior exposure (check IP spec per SKU).
  • Safety: supply fused harness recommended; recommended inline fuse 1–5A, depending on install and total circuit draw.

    The collection integrates visual customisation options (logo projection, RGB settings) and safety features (yellow/amber for enhanced visibility near water). Products are designed to interoperate with 3-wire or 2-wire trigger logic, factory harnesses, and aftermarket relay kits, enabling plug-and-play OEM replacements or splice-in custom installs.

Why Choose Underground Lighting Universal Puddle Lights?

  • 3 Practical Safety Gains at Night

    Puddle lights illuminate the ground 0.5–2.0 m from the door, reducing slip/trip incidents and improving curb-step awareness when exiting in low light.

  • 2 Installation Modes (Plug-and-Play or Hardwire)

    Vehicle-specific kits offer plug-and-play OEM connectors, while universal pucks support splice-in or relay-controlled hardwires, preserving factory dome logic and preventing battery drain.

  • 120°–180° Flood Beam for Reliable Ground Coverage

    Wide beam angle minimises shadowed zones under the door and reveals obstacles (curbs, puddles, debris) immediately where users step.

  • Low Electrical Draw — Vehicle Battery Friendly

    Typical LED puddle lights draw <1A at 12V (≈1–10W), significantly less than legacy halogen puddles, lowering parasitic load during repeated door cycles.

  • 3 Color/Function Choices for Use-Case Precision

    White (5000–6000K): maximum contrast for loading/maintenance
    Yellow: improved penetration near reflective water or fog
    Blue / RGB / Logo: aesthetic or thematic uses (off-road/show), not recommended for public road signalling in many jurisdictions.

  • More than 10× Lifetime vs Incandescent

    Solid-state LEDs typically exceed 25,000 hours, reducing replacement frequency and maintenance for fleet and private owners.
