LED seat row indicators SRA, SRB and SRC for theatres, cinemas and auditoriums.
Illuminated row markers with custom numbers, letters or symbols help visitors find the correct row in a darkened auditorium. Compare SRA, SRB and SRC by size and mounting position, then send your seating plan for a project-specific quotation.
Clearly legible in the aisle – without distracting from the stage or screen.
Seat row indicators are a compact element within an auditorium, yet they sit directly in the audience’s line of sight when entering. Housing format, light colour, brightness, mounting position and the surrounding step lighting should therefore be coordinated as one system.
A single or double-digit row number requires less surface area than a directional arrow, pictogram or longer custom text.
Depending on the model, the indicator can be mounted directly onto a step profile or installed separately on floors, seat end standards or walls.
Light colour, brightness and operating voltage (12 V or 24 V DC) are matched to the surrounding aisle and step-lighting installation.
Compare SRA, SRB and SRC seat row indicators
You do not need to choose a model before contacting us. Check the available mounting surface and the numbers, letters or symbols you need – we will recommend a configuration that suits your venue and step lighting.
SRA
When a compact, symmetrical row number or letter is required on a square mounting area or step profile.
SRB
When vertical mounting height is restricted – for example on narrow surfaces or integrated into the SLR step profile.
SRC
When larger digits, directional arrows, pictograms, logos or longer custom inscriptions require more space.
How the three formats compare at scale.
SRC offers the largest inscription area. SRA is square, while SRB is lower and slimmer. The front faces are shown here at the same relative scale.
Format still open? A photo of the mounting area and the desired row marking are enough for an initial recommendation.

SRC · 120 × 60 mm
Large-format indicator with extra space for numbers, directional arrows, pictograms, logos or longer custom text.
Mounted on an LED step profile or installed separately.
SRA can be integrated directly onto SL1, SL2 or SLD step profiles; SRB fits onto SLR. All three models (SRA, SRB and SRC) can also be mounted independently on suitable floor, seat-standard or wall surfaces.
Optionally integrated on SL1, SL2 and SLD LED step profiles.

Inscription, light effect and connection tailored to your venue.
So that seat row indicators and step lighting operate as one coherent visitor-guidance system, we coordinate the inscription, light colour, brightness, supply voltage, cabling and mounting method together.
One coordinated visual language for steps and seating.
When seat row indicators are ordered together with LED step profiles or recessed luminaires, we coordinate mounting positions, 24 V power supplies, dimming and cable routes as a single project package.
Common questions about illuminated seat row indicators.
Which seat row indicator should I choose?
SRA is suited to compact square mounting areas (60 × 60 mm). SRB is designed for lower rectangular mounting heights (67 × 36.8 mm) and integration with the SLR step profile. SRC (120 × 60 mm) provides a larger surface area for bigger digits, pictograms, directional arrows or logos.
Can the indicators be customised?
Yes. Row numbers, letters, pictograms and – depending on the model – directional arrows or project-specific logos are manufactured to match your seating plan.
Are SRA, SRB and SRC available for 12 V and 24 V DC?
Yes. All three models can be configured for 12 V DC or 24 V DC to match your existing or new step-lighting power supply.
Can the indicators be mounted on LED step profiles?
Yes. SRA can optionally be mounted on SL1, SL2 and SLD step profiles. SRB can be integrated on the SLR profile. SRC is designed for separate surface mounting rather than mounting on a step profile.
Can the indicators also be mounted separately?
Yes. SRA, SRB and SRC can all be installed independently of a step profile on suitable floor, seating or wall surfaces. Fixing and cable routing are coordinated for each project.
Which light colours are available?
Several white tones and project-specific colours are available. The exact light colour and brightness are matched to the model, room ambience and surrounding step lighting.
Where can I find technical drawings and data sheets?
Dimension drawings for SRA, SRB and SRC are shown directly on this page alongside links to the English PDF data sheets. The drawings show the standard housing geometry; project-specific fixing, inscriptions and cable exits are coordinated before production.
What information is useful for a quotation?
Helpful details include a seating plan, approximate quantity, desired row numbering or symbols, photos and dimensions of the mounting surface, as well as operating voltage and preferred light colour if already known.
