DARKGUARD Magnetic Led Trailer Lights with Cable 7.5m & 7 Pin Trailer Plug
Product description
What it is and what it solves
DARKGUARD’s Magnetic Led Trailer Lights are a plug‑and‑play rear lighting solution designed for 12V and 24V vehicles, including trailers, caravans and worksites. The kit arrives pre‑wired with a 7.5m extension lead and a 7‑pin trailer plug, so you can mount the lights using the built‑in magnets and simply connect to the vehicle socket. This reduces setup time and avoids complicated wiring on site.
How it’s built and what to expect

Each light contains 14 LEDs, delivering a total of 28 LEDs per pair. The housing combines ABS + PBT with a PMMA lens, built to withstand a wide temperature range from -40°C to +65°C and offer durability in outdoor conditions. The unit is rated IP67 for water and dust resistance, making it suitable for trailer and boat use as well as general towing duties.
What stands out in everyday use


The magnets on the rear surface secure the light to the vehicle’s rear, helping with quick mounting and removal. The kit covers multiple functions in one unit: rear position tail lamp, direction indicator, brake/stop light, license plate illumination, and reflector. This consolidation means fewer separate lights to manage and less crew time on installation.

Limitations and cautions to keep in mind
On paper, it’s versatile for 12V/24V systems, but the exact compatibility depends on your trailer’s wiring and socket. Even with pre‑wired lead, you’ll want to check that your vehicle’s 7‑pin plug matches the supplied connector and that the magnets are suitable for the mounting surface. If you prioritise a light with independent side indicators or auxiliary features, you may find this unit’s all‑in‑one approach sufficient but not expansive.
Who it’s for

This product is well suited for caravaners, boat trailers, agricultural trailers and general trailer owners who want a robust, all‑in‑one rear lighting solution with straightforward installation. It’s also appropriate for users who value a pre‑wired, plug‑and‑play setup that minimises additional wiring on a job site.


Who it isn’t ideal for
If you require bespoke, high‑brightness signalling or advanced lighting configurations beyond the standard rear/indicator/brake/license plate functions, this unit may feel limited. It also may not be the best option if your mounting surface cannot support magnetic attachment or if you need separate left/right light modules instead of a shared pair.

When it makes sense to buy
If you want a practical, weather‑proof rear light solution that covers multiple functions in one compact unit and can be fitted quickly to a wide range of trailers, this setup offers a sensible balance of durability and simplicity. The IP67 rating and wide operating temperature range add peace of mind for outdoor use, while the 7‑pin plug eliminates extra wiring steps.
What to review before purchase



Confirm that your trailer’s 7‑pin socket and vehicle electrical system align with the supplied lead and plug. Check that the trailer mounting surface can accommodate the magnetic fix and that no ferrous interference blocks magnet adhesion. Consider how the integrated license plate light meets local vehicle lighting regulations.
Practical usage example
Imagine you’re hitching a boat trailer after a weekend on the coast. With the pre‑wired 7.5m lead, you simply attach the magnetic lights to the rear, plug into the 7‑pin socket, and verify that the tail, brake and indicator signals register correctly on the tow vehicle. The IP67 protection means you won’t worry about spray or rain during docking, and the compact size fits neatly on most trailer rear profiles.
