eSynic Trailer Light Set Professional 2pcs 12V with 7.5 m cable (E-Mark)
Product description
What it is and why people buy it
This eSynic Trailer Light Set Professional is a pair of 12V rear trailer lights designed to cover the jobs you typically need at the back of a trailer: tail/rear illumination, brake indication and indicator function. It’s built around an “easy fit” approach, with a screw-in attachment method and a 7-pin style connection you can plug into your trailer’s electrics.
On paper, the appeal is pretty clear: if you’re tired of bodged wiring or limited cable length during replacement, this kit is set up to make the install feel more straightforward. You also get extras focused on visibility, including an integrated licence plate light and a rear reflector.
Key takeaways
You’re essentially choosing a complete rear light set that’s aimed at getting your trailer lighting back into a usable, road-ready state with less hassle than some basic replacements. The kit also leans into compliance and durability for real-world use, not just a quick swap.

Worth noting, though: while it’s marketed as “E-Mark” certified and compliant with ECE R1 regulations, you’ll still want to make sure the rest of your trailer’s setup (wiring, plug type, mounting position) matches what you have. A good lighting kit won’t fix an incompatible connector or mismatched mounting space.
What you’ll notice day to day
The practical side is the way the lights are meant to go on and the way you’re meant to connect them.
The lights are described as having a screw-in design secured with screws. That matters because a loose rear light is one of those annoyances you notice immediately when driving over bumps. There’s also an extended 7.5 m cable, which should help if your trailer wiring run isn’t right next to the mounting points.


For everyday driving and checks, the functions mentioned are “indicator lights, brake lights and tail/rear lights”, plus the integrated licence plate light and rear reflector for additional visibility. If you regularly do short trips in changing weather, that visibility angle is where sets like this earn their keep.

And yes, they’re designed for wet conditions: the kit is rated IP65 waterproof, so it’s built to cope with rain and road spray rather than requiring kid-gloves treatment.
Where it stands out
A few parts of this set feel especially targeted at buyers who want less grief during installation and more confidence in bad weather.
- E-Mark certified design and compliance with ECE R1 regulations (as stated).
- Screw-in mounting for a more secure attachment.
- European-style 7-pin connector intended to plug into a trailer’s 7-pin plug.
- IP65 waterproof rating, made for wet conditions.
- Durable construction materials listed as PMMA and ABS.
The integrated licence plate light and rear reflector are also a sensible inclusion, because visibility is rarely just about the main tail lights.

Limitations: some technical items aren’t provided in the information you shared (dimensions, weight, cable type/connector specifics beyond the “European-style” 7-pin plug idea). That doesn’t make it worse for most installs, but it does mean you should double-check physical fit and cabling routing before ordering.


Who it suits (and who should be careful)
It’s a good fit if you’re replacing worn or missing rear trailer lights and you want a kit that’s built around a plug-in style connection and a reasonably long cable run (7.5 m). It also makes sense if you regularly tow in damp weather and you care about waterproofing, not just brightness.

It may not suit you if your trailer’s wiring doesn’t match the mentioned 7-pin style plug, or if the mounting positions don’t line up with a screw-in installation. Also, if you’re looking for highly specific “fit-for-a-particular-model” compatibility, you’ll need to confirm that level of compatibility from your trailer setup first—this listing describes the kit broadly for trailers/camper vans/trucks/tractors, but doesn’t spell out vehicle-model matching.
Practical tips before you buy
A bit of pre-checking can save time:
- Confirm your trailer has the 7-pin plug you need for the European-style connector.
- Measure (or at least visualise) the cable run so the 7.5 m length actually routes cleanly without tension.
- Check where the screws will go and whether you have space for the mounting approach.
- If you’re aiming for compliance as part of your decision, keep the stated ECE R1 and E-Mark info in mind—but still verify it aligns with your local requirements.
One simple real-life example: if your existing left/right rear light units have been removed and you’re left with cables dangling at one end, a longer cable can help you position the new lights properly rather than forcing the mounts closer than you’d like.

Should you buy it?
This eSynic 2-piece 12V trailer light set is worth considering if you want an installation that’s geared towards plugging into a 7-pin trailer setup and mounting securely with screws, with a waterproof build (IP65) and an extended 7.5 m cable included. The integrated licence plate light and rear reflector are also a sensible safety-focused bonus.


You may want to skip it if your trailer electrics or mounting points don’t match what this kit expects—particularly the 7-pin connector and the screw-in placement. It’s not perfect for every situation, but for many straightforward replacements it’s the kind of “complete kit” that reduces the usual faff.
