Justech 2pcs LED Side Marker Lights (Triple Colour) 12–30V, IP65, 74mm for Truck Trailer, Lorry, RV & Caravan
Product description
The essentials
If you drive or maintain a truck, trailer, lorry, or caravan, side marker lights are one of those small things that matter more than they look. They help vehicles stand out in low light and bad weather, and they can improve visibility from different angles.
This Justech 2pcs LED Side Marker Lights kit is built around a triple-colour approach (yellow/white/red) and a fairly straightforward installation concept. You’re basically choosing a compact, weather-rated set for side positioning and clearance-style marking—rather than a fancy lighting system.
Worth noting, the product description talks about “Road Traffic” approval with E-marks. That’s useful when you’re trying to keep things legal, but it’s still sensible to check your vehicle’s specific requirements before fitting.
What stands out in day-to-day use
The most convincing part on paper is the combination of brightness-focused LED design and triple-colour visibility. The lights are described as using 3030 LED chips, and the lens/housing is made to keep the unit sealed. In practical terms, this kind of side marker is the sort of upgrade you buy to replace ageing markers, restore a clearer outline of the vehicle, and keep consistency across front and rear positions.
The body material is also presented as silicone. For a side marker, that can matter because it’s typically better suited to flex and resistance in real-world vibration than hard plastic components. Again, you’re not getting a miracle lamp, but the materials and the sealing concept aim to tackle common weak points.
A useful micro-scenario: imagine you’ve got a trailer running on country roads at dusk, and one side marker looks dull or cracks over time. Replacing it with a sealed LED unit like this is a straightforward way to bring the vehicle back to a more defined, visible silhouette.
Key features

- Built with 3030 LED chips, described as high brightness.
- Silicone construction for resistance, flexibility and corrosion resistance.

Limitations and what to double-check
No product like this is perfect for every setup, and a couple of details are worth confirming before you commit.
First, the listing refers to a 74mm length “for mini side”. If your mounting space is tight or you’re replacing an existing unit with a different footprint, measure the available area and check the mounting approach you currently use. Side markers tend to be unforgiving when the size doesn’t match.
Second, the “triple colour” claim is helpful, but it doesn’t explain whether colour selection is automatic, dependent on wiring, or tied to position. You’ll want to review how your current wiring is arranged and how you expect the light to behave on your specific vehicle.
Finally, the listing mentions installation simplicity and polarity (Red positive, Black negative). Still, trailer and caravan wiring can vary—so it’s smart to verify polarity and fitment rather than assuming every harness matches.
Who it suits (and who should skip it)
It’s a solid pick if you need compact, weather-resistant LED side marker lamps for a trailer/lorry/caravan style application, and you prefer a sealed unit designed for rain, snow, and fog conditions (IP65 is the key headline here).
It may not be the best match if you’re after a specific mounting design that requires a different size or beam arrangement than a mini 74mm marker lamp. And if colour behaviour is critical to your current lighting configuration, you’ll want to confirm how the yellow/white/red output is intended to work with your wiring.
Is it worth it?
You should buy it if you’re looking for replacement-style LED side markers that lean into triple colour visibility, a sealed IP65 build, and an E-marked approach for road-traffic compliance (as stated in the listing). It makes sense for people who do routine maintenance on trailers, RVs, caravans, and lorries, and want something practical rather than complicated.
You may want to skip it if your mounting space doesn’t suit a 74mm mini marker, or if you need guaranteed behaviour from the yellow/white/red channels without any uncertainty about wiring and how the colours present on your vehicle.
