Mobile Traffic Lights
V11 portable traffic lights for alternating traffic on narrowed sections.
Mobile traffic lights for roadworks
When a lane is closed for works, the two directions have to take turns through what is left open. A worker with a STOP/GO paddle can manage that for an hour, but for days or weeks you need traffic lights. Under the Romanian standard SR 1848-1:2024, the V11 mobile traffic light is placed on a narrowed section of road, one at each end, to let the two directions through alternately.
The V11 sets
- V11-20 – a set of 2 mobile traffic lights, without countdown;
- V11-21 – a set of 2 mobile traffic lights with a countdown on the middle light, so waiting drivers can see when the change is coming.
Each light has 3 Ø200 mm LED lamps, red, yellow and green, and its own control unit. It stands on a wheeled trolley, so it moves easily from one job to the next. A set weighs 70 kg. The sets are supplied without car batteries, which are bought separately.
Spare parts
On a site, a traffic light can get knocked over or a single lamp can fail. There is no need to buy another set; you replace just the part:
- V11-D200-R, V11-D200-Y and V11-D200-G – the red, yellow and green Ø200 mm LED lamps, sold separately, for the V11-20 set;
- V11-SUPORT – the complete signal head, the 75 cm housing with all 3 lamps, for the set without countdown;
- V11-CONTROL – the control unit, with a display and buttons for setting it up; each traffic light has one.
How to choose
For ordinary works, the V11-20 set is enough. On a long section, where red lasts longer, the V11-21 countdown set helps drivers: they can see how long is left until green. For repairs, start from what has broken: a lamp that no longer lights, a cracked housing or the control.
Complete the works signage with traffic cones and warning lights. We deliver within 24-48 hours.
? Frequently asked questions
What is the difference between the V11-20 and the V11-21?
The V11-21 has a countdown on the middle light of each traffic light, so drivers can see when the change is coming. Otherwise the sets are the same: 2 mobile traffic lights, each with 3 Ø200 mm LED lamps, a control unit and a wheeled trolley.
Are batteries included?
Where are mobile traffic lights placed?
Under SR 1848-1:2024, on a narrowed section of road, one traffic light at each end, to let the two directions through alternately, for example when a lane is closed for works.
Can I replace just one faulty lamp?
Yes. The Ø200 mm LED lamps are sold separately: red V11-D200-R, yellow V11-D200-Y and green V11-D200-G, for the V11-20 set. For a complete signal head on the version without countdown, there is the V11-SUPORT housing with lamps.
What does the V11-CONTROL control unit do?
It switches the lamps and runs the red-yellow-green cycle, and it is set up from the display and buttons on its front panel. Each traffic light has its own unit, so a set has two, and the V11-CONTROL is the spare part.
