Product description
What it is and why people buy it
This Yuanjoy 2‑piece LED trailer rear light set is designed for use on trailers and similar vehicles where you want a bright, multi-function rear lighting setup in one go. On paper it covers the usual rear lighting jobs: driving/running, braking, dynamic indicators, reverse, a rear fog function and even a licence plate light. For anyone doing a trailer, van, caravan or truck update, that “all in one unit” approach can be handy because you’re not hunting multiple separate components.
It’s built around LED light elements (72 LED per unit are mentioned) and a thickened PC (polycarbonate) housing. That combo is aimed at keeping the light visible and consistent in real-world conditions, including wet weather, where a sealed approach matters.
The essentials (key features that affect day-to-day use)
The selling point here isn’t just that it’s LED. It’s the combination of multi-function outputs and weather resistance.
The unit is rated for 12V/24V DC operation (10–30V DC is listed), and it’s described as IP67 waterproof. In practical terms, that’s the kind of protection you’d look for if your trailer tends to get splashed by road spray or sits outside between trips.
The housing is described as sealed PC, “scientific and transparent” in the original wording. You can take from that that the lens/housing is intended to keep water out and keep the beam clear rather than relying on loose covers. It also claims quick illumination with no lag, which is exactly what you notice when you brake or indicate.
Tech specs that matter when you’re choosing
Here are the concrete details provided that are most likely to influence whether this set fits your plan:
- Power/voltage range: 10–30V DC (12V/24V system)
- Number of LEDs: 72 LED beads per light
- Housing material: PC (polycarbonate) plastic
- Waterproof rating: IP67
- Operating temperature (as stated): from less than 40° to 65°
- Dimensions (per light): 30 cm long, 13.5 cm wide, 4 cm high
- Supplied cable length: 40 cm
- Light design type: 2835 LED model design
There’s also a list of certifications/compatibility references (ECE R3, R6, R7, R23, R38 and EMC R10). That can help if you’re trying to stick to a particular compliance expectation, but do double-check what exactly applies to your vehicle/trailer setup—documentation expectations can vary.
What you’ll notice in use (and the one limitation to keep in mind)
The multi-function layout is what you’ll see first. With one rear lamp covering driving/running, brake, indicators and reverse, it simplifies the wiring situation compared with mixed, single-function lights—assuming your mounting and connectors can be made to suit.
As for brightness, the claim is that it provides clear and bright road visibility, with rapid switching “without delay”. That’s a benefit for safety-critical moments like braking and indicating.
However, a limitation to flag: the cable length is 40 cm, so depending on where your wiring point is and how your trailer body routes cables, you may find you need additional wiring/extension work. If you prefer minimal hassle, it’s worth checking this before buying.
Where it shines, and who should consider it
It tends to make sense if you:
- want an LED rear lamp set for trailer/van/caravan/truck-style use where weather resistance is a priority
- are specifically looking for a multi-function rear light arrangement (running/brake/indicators/reverse/rear fog and licence plate light)
- prefer a sealed PC housing concept for outside use rather than something that’s likely to let water in
It also looks aimed at people who want a practical upgrade path. The listing frames this as suitable for rear light updates on trailers and similar vehicles.
When it may not suit your needs
It might not be a great match if:
- you’re replacing only one function and want a simple single-purpose unit (this is a multi-function set, so you’re paying for features you may not use)
- your mounting space is tight. The dimensions are given, but those measurements need to line up with your existing cut-outs or mounting brackets.
- you require very specific compliance documentation details for your exact vehicle/trailer—there are certification references listed, but you should still verify what’s relevant in your case.
FAQs about buying and fitting
Should I worry about it being 12V/24V?
The set is described as 12V/24V compatible, with a listed DC operating range of 10–30V. That suggests it’s intended for common trailer electrical systems, but you’ll still want to confirm your vehicle output is DC and falls within that range.
How waterproof is IP67 in everyday terms?
IP67 indicates strong protection against dust and immersion to a depth within the standard’s parameters. For buyers, the practical takeaway is that it’s built to cope with wet roads and rain, rather than being a “splash resistant only” type of light.
Does it include the licence plate light functionality?
Yes, the description states it includes a rear licence plate light. You’ll want to check how that portion is meant to sit relative to your plate area so it lines up properly.
What about wiring—will the 40 cm cable be enough?
That depends on your trailer layout. The listing says the light comes with a 40 cm cable. If your mounting location is far from the wiring point, you may need extra cable work.
Final verdict
If you’re planning a rear lighting upgrade for a trailer or similar vehicle and you want a sealed, multi-function LED setup in a compact housing, the Yuanjoy 2‑pcs set is worth considering—especially for wet-weather use thanks to the IP67 rating and PC housing approach.
Just don’t buy on autopilot: check the 30 cm length, 13.5 cm width and 4 cm height against your mounting space, and make sure the 40 cm cable length doesn’t force you into major rewiring. If you only need one rear function, this may end up being more complexity (and more cost) than you actually need.
