COLFULINE 2Pcs 12V Magnetic Trailer Tail Lights with 10m Cable and 7-Pin Plug
Product description
What this is and what it solves
COLFULINE offers a pair of magnetic, 12V trailer tail lights designed for quick, tool-free installation. With durable ABS housings, PMMA lenses and built-in high-strength magnets, they attach to metal surfaces without drilling or permanent wiring. This makes them handy for temporary towing, emergency situations or sharing lighting between trailers, agricultural machines or other plant vehicles. The kit includes a 10-metre wiring loom (7.5m main cable plus 2.5m cross-connection) to keep the install tidy and reduce cable clutter.
What stands out on paper

On the bench, it’s clear these lights prioritise portability and ease of use. The magnetic mounting plus rubber-coated contact area minimises scratches while granting strong adhesion. The long wiring run means you can reach a power source without relocating the trailer, which is useful for temporary setups. They’re IP65 weather-rated, which gives a practical level of protection against dust and water jets—enough for typical outdoor towing tasks and farmyard conditions.
Limitations and practical considerations


If you’re expecting a permanent lighting solution with no re-mounting, these magnetic lights may feel more like a temporary or supplementary option. The system relies on a metal surface for adhesion, so non-metallic trailers or vehicles would need alternative mounting. Moreover, while IP65 helps against weather, actual road or off-road exposure can reveal wear over time if the magnets aren’t seated securely.

Who this is for
This kit suits owners who value flexibility and fast setup: you might tow occasionally, lend equipment between trailers, or want an economical backup lighting option. It’s particularly relevant for agricultural use or light commercial tasks where permanent wiring isn’t practical or desirable.
Who it isn’t ideal for

If you need a fixed, long-term lighting arrangement or a lighting system with integrated wiring in a single trailer, fixed lamps or professionally wired kits could offer more durability over years of use. If you regularly expose the setup to rough handling or frequent repositioning, you may notice the magnets wear or surface scratches if not careful.


When it makes sense to buy
Consider this kit when you prioritise quick deployment, transferability between trailers or equipment, and a straightforward, cable-managed installation. The 10 m wiring loom reduces the need for extra extensions and helps keep the installation neat, which is convenient for temporary or shared-use setups.

What to check before buying
- Confirm the trailer or vehicle has a suitable metal surface for magnet mounting.
- Ensure your power source is compatible with 12V operation and the 7-pin plug configuration.
- Inspect the weather exposure at your usual operation sites, IP65 is solid for most outdoor uses, but harsh off-road environments may demand occasional maintenance.
- Consider how often you’ll relocate the lights, frequent repositioning could accelerate wear on mounting surfaces.
Practical use example



Imagine you’re moving a small agricultural trailer between fields. You snap on the two magnetic tail lights in seconds, route the 10 m cable along the chassis, plug into the 7-pin harness, and you’re ready to tow. If you later need the same lights on a different trailer, a couple of vibrations and a quick reattachment is all that’s required—no drills or rewiring.

Is it worth it?
You’ll like it if you value portability and a low-effort setup for occasional towing or equipment sharing. It may not be the best fit if you need a permanent, fixed, high-mileage lighting solution or if the magnet mounting isn’t compatible with your trailer’s metal surfaces. For many casual or light-use scenarios, the flexibility and simplicity are compelling advantages.
