LED Trailers — Mobile Outdoor Displays You Can Drive To Site and Switch On In Under an Hour

An LED trailer is a road-towed unit with a large-format LED screen mounted on a purpose-built chassis. Tow it to site, deploy the screen (most units use a hydraulic or manual mast lift), connect the generator or solar feed, and you have a full-brightness, full-colour video display in operation — typically within 30 to 60 minutes from arrival.

Dynamo’s trailer fleet covers everything from compact single-sided P5 units for tight urban locations through to large dual-sided P6/P8 screens on tri-axle chassis for major outdoor events. Every model in stock has been built for UK road use and weather: IP65-or-better sealing, daylight-readable brightness above 5,000 cd/m², and either integrated diesel generator or solar-plus-battery for off-grid deployment.

What People Actually Use LED Trailers For

The use cases we book against most often:

Outdoor events — festivals, sports fixtures, agricultural shows, concert site information. The trailer arrives the morning of the event, sits as event signage, live feed screen or sponsor branding through the day, and leaves with the strike crew.
Election and political campaigning — mobile messaging that can be re-positioned daily, typically with quick-change graphics or live-broadcast feeds during major rally days.
Highways and traffic management — Variable Message Sign (VMS) trailer units for lane closures, diversion routes and incident messaging. The solar-powered VMS variants in our range meet UK National Highways and TfL approvals for unattended deployment.
Public information and emergency response — councils and Civil Defence partners use mobile units for flood warnings, community announcements and safety messaging during major incidents.
Brand activations and product launches — the trailer travels to a city centre, sits for the activation window, then moves to the next city. Cheaper and faster than building temporary structures.
Construction and infrastructure — site safety messaging, public liaison content, contractor branding at major works.

Solar-Powered and Off-Grid Models

Three units in our current range run entirely off solar plus battery storage with no generator. They’re the default choice when:

The deployment site has no mains supply and a generator would be unacceptable for noise, fuel or emissions reasons (rural sites, environmental sensitive zones, residential streets, overnight unattended deployment).
The deployment window is daytime-heavy — solar yields enough overnight battery charge to drive the screen through the next operating day at typical signage brightness.
The end user requires low-carbon or net-zero credentials for the campaign or event.

The solar VMS variants in particular get specified into UK highways contracts because they require no fuel logistics for unattended multi-week deployments.

For fixed (non-mobile) outdoor display options, see our LED video wall range. For events where the trailer isn’t the right form-factor (indoor stages, modular tour kit), our LED screen hire service covers rental of conventional cabinet-based screens.

Frequently Asked Questions

What screen sizes are available?
Our trailer range covers screens from approximately 5 m² (single-sided compact units, suited to tight urban deployments) up to approximately 25 m² (dual-sided or tri-sided large units, suited to festival main-stage or major sports fixtures). Each individual product page lists exact screen dimensions and available pixel pitches.

Do I need a specialist licence to tow one?
It depends on the trailer’s gross train weight (GTW). Smaller LED trailers — typically those under 3,500 kg combined — can be towed with a standard UK category B car licence. Heavier units require category BE, and the largest dual-axle units may need a category C1 or specialist HGV operator. We confirm exact licensing requirements per model on enquiry.

Can content be updated remotely?
Yes. All current trailer models support USB, laptop and (on most models) 4G or Wi-Fi remote content management. For longer deployments we can supply a cloud-managed content interface so the on-site operator just connects power; the content is pushed remotely.

What’s the lead time?
Hire stock is usually available with 7–14 days notice depending on date and unit size. Major events (festival season, election campaigns) book out months ahead — speak to us as early as possible. Purchase lead times depend on the spec and run typically 8–14 weeks.

Contact our team with your deployment dates, location and approximate audience size and we’ll spec the right trailer and content workflow for the job.
