DARKGUARD 2 x Square Trailer Rear Lights LED – IP67, 12V/24V
Reviews
Product description
What it is and who it’s for
DARKGUARD’s square trailer rear lights come in a two‑lamp set designed to work with a broad range of vehicles, including trailers, trucks, caravans and motorhomes. If you’re looking for a compact, all‑in‑one lighting solution that covers brake, position, indicators, and rear‑number plate illumination, this 5‑in‑1 setup aims to simplify sourcing and wiring.
Why it might be worth considering

On the paper, these lights balance function with practicality. The 5‑in‑1 design consolidates several functions into one unit, which can reduce clutter on the tail end of a trailer or caravan. The lens is made from a high‑transparency PMMA material described as unbreakable in practice, while the housing is designed to withstand the road with a screw‑mount and shock resistance. The LED array is 40 diodes, pitched as energy saving and long‑lasting, which can matter if you’re ticking down running costs over time.
Build and key specs you can rely on
- 12V and 24V compatibility makes them versatile for different vehicle electrics.
- Dimensions: 105mm x 95mm x 28.5mm, bolt distance 70mm, wiring length 28 cm.
- IP67 waterproof rating means solid protection against water exposure in typical trailer conditions.
- Lens is PMMA, marketed as long‑distance visible and impact resistant.
- Operating range claimed from -40°C to +65°C, designed for all‑weather use.
- 5 functions in one unit: brake, position, turn signal, number plate light and reflector.
- Brass/ copper conductor noted as preserved pure copper cable for good conductivity.



How it behaves in real‑world use
If you’re wiring a trailer or caravan, the 28 cm lead length is a practical consideration—short enough for tidy runs on many builds but long enough to reach common wiring points. The IP67 seal gives peace of mind in muddy sites or winter trips, though you should still mount and seal connections properly to maximise longevity. In day‑to‑day use, you may notice the 5‑in‑1 format is convenient when replacing older, lower‑spec lamps, it can reduce the number of separate fittings you need.
What’s strong and what isn’t quite perfect

- Strengths: compact 2‑lamp kit, 5 functions in one, robust sealing, wide operating temperature, compatible with 12V/24V systems, clear PMMA lens for visibility.
- Limitations: the description does not specify lumen output or exact brightness per function, and real‑world performance can depend on wiring quality and vehicle compatibility. If your trailer wiring uses unusual CAN or bespoke connectors, you may need an adapter or professional installation.
Who it’s for
This set suits trailer clubs, caravan owners, farm vehicles and light commercial operators who value a consolidated rear light unit. It’s particularly appealing if you want a single, universal lighting solution across different vehicle types that you service or own.



When it makes sense to buy
Consider this kit if you need a straightforward 12V/24V solution with multiple functions consolidated into a single unit and you’re able to fit square, bolt‑on lamps with a 70 mm hole pattern. It’s also reasonable where IP67 protection and a broad operating temperature range align with your common use cases—think rural control cabinets, boat trailers, or camper builds exposed to the elements.
When it might not be the best option

If you require very high brightness for daytime visibility, or if your wiring setup demands very long lead runs, these lamps may not meet every spec out of the box. Also, if you need explicit lumen figures or guaranteed performance under severe vibration beyond standard road use, you may want to compare with products that publish more detailed photometric data.
What to check before buying
- Confirm the fixed bolt distance (70 mm) matches your mounting holes.
- Ensure your trailer’s electrical system supports 12V or 24V operation and that you have the appropriate wiring length for 28 cm leads.
- Check that the 5‑in‑1 configuration aligns with the light requirements for your location (UK/EU regulations for trailer lights).



How this compares with other approaches
If you want maximum brightness and the ability to tailor each function individually, you could look for separate lamps for brake/indicator/position. The DARKGUARD approach trades some granular customization for simplicity and a compact, all‑in‑one unit that’s arguably easier to install on smaller trailers or rigid towing setups.
Practical usage example
You’re replacing a damaged rear light on a mid‑sized trailer. With the two square units, you can run a single harness along the chassis, mount each lamp with the 70 mm bolt spacing, and rely on the sealed IP67 design to handle a muddy tow path and occasional rain without immediate concerns about water ingress.
FAQ
- Do these lights work with 12V and 24V vehicles? Yes, they’re specified for both voltages.
- What does IP67 mean for trailer lighting? It indicates strong protection against dust and immersion in water up to 1 metre for short periods.
- Is the wiring length sufficient for most trailers? The 28 cm lead is typical for many builds, but check your wiring route before purchase.
Final verdict
Is it worth it? Worth considering if you prioritise a compact, 5‑in‑1 rear lighting solution that covers essential functions and offers robust sealing for all‑weather use. It’s a sensible choice for mixed fleets or DIY trailer builds where standardised, easy‑to‑fit lights save time. If you prioritise detailed lumen data or peak brightness for high‑traffic areas, you may want to explore options that publish photometric specifications or offer modular light sets.
