Magnetic USB Car Trunk Dome Light – 30 LED Auto Sensor
Magnetic USB Car Trunk Light – Automatic 30-LED Dome Lamp
Never fumble in a dark trunk again. This smart magnetic dome light snaps instantly onto any metal surface and switches on automatically when light levels drop — giving you bright, even illumination right where you need it. Whether you're loading luggage, rummaging through a roof cargo box, or lighting up a camping tent, this compact 30-LED bar delivers powerful white light without the hassle of wiring or battery swaps.
Key Features
- Auto Magnetic Induction: Highly sensitive sensors detect low-light conditions and switch the light on automatically — no buttons, no fumbling.
- 30 High-Brightness LEDs: Uniform, soft white illumination covering the full interior of your trunk, roof box, or cargo area for clear visibility.
- USB Rechargeable Battery: Built-in 500 mAh battery provides up to 50 days of use on a single charge — simply plug in via USB to recharge, no disposable batteries needed.
- Strong Magnetic Base: The powerful magnet on the underside attaches firmly and securely to any metal surface — trunk floors, lids, roof racks, and more. An adhesive iron patch is included for non-metal surfaces.
- Compact & Versatile: At just 16 cm long, this slim light bar fits easily in tight spaces and works equally well as a reading light, search light, luggage light, or auxiliary camp light.

Frequently Asked Questions
Q: How does the magnetic car trunk light turn on automatically?
A: The light is equipped with a built-in magnetic induction sensor. It detects changes in ambient light levels and activates automatically in dark or low-light conditions — such as when you open your trunk at night — so you always have hands-free illumination without pressing any buttons.
Q: How long does the battery last and how do I recharge it?
A: The built-in 500 mAh rechargeable battery provides up to 50 days of use on a full charge under typical usage patterns. Recharging is easy — simply connect the included USB cable to any USB power source (power bank, wall adapter, laptop, etc.). Please note: do not use the light while it is charging.
Q: Will this light stick to plastic or fabric surfaces in my trunk?
A: The primary attachment method is magnetic, so it works best on metal surfaces. For non-metal surfaces such as plastic trunk liners or fabric-lined cargo areas, the included adhesive iron patch can be stuck to the surface first, allowing the magnetic base to attach securely to it.
Q: Can this dome light be used outside of a car?
A: Absolutely. While it's designed primarily for car trunks, the 30-LED magnetic light bar is also perfect for roof cargo boxes, truck beds, camper vans, camping tents, closets, and anywhere else you need portable, hands-free lighting.
