Free twin head street light CAD block in DWG

A twin head street light carries two luminaires on a single column — either two arms reaching out to opposite sides, or two heads on a feature post — so one pole does the work of two. This page offers a free twin head street light CAD block in DWG and DXF, drawn at true millimetre height so the column and its pair of arms read correctly in a boulevard elevation, a central-reserve section or a plaza streetscape. It is free for commercial use with no signup or watermark.
Twin head lights solve a specific problem: lighting two areas, or a wide space, from a single column, which keeps the number of poles down and gives a boulevard a formal, symmetrical look. On the drawing the symmetry is the point, so the block keeps both arms and heads balanced about the column. Whether the post sits in a central reserve lighting both carriageways or on a boulevard with twin lanterns, the block puts the geometry on the page ready for masterplans, road sections and public-realm boards.
What a twin head configuration looks like
There are two common twin head arrangements, and the block reads for both. The first is a functional double-arm column in a central reserve, with one arm reaching over each carriageway so a single pole lights both directions of a dual carriageway. The second is a decorative twin-lantern feature post, with two heads on symmetrical arms used along boulevards, in plazas and on bridges for a formal, balanced look.
Either way the defining feature is the pair of heads balanced about the central column, and that symmetry is what the block captures. It is drawn as clean geometry on tidy layers so the column and the two arms stay separate, prints sharply at public-realm scales, and updates everywhere from one edit as a true block reference.
Height, reach and symmetry to design around
Use these ranges and confirm against the scheme. A central-reserve twin head highway light commonly sits in the 8–12 m mounting-height band so each head clears its carriageway, with each arm reaching out in the 1–3 m range to sit over the running lanes. A decorative boulevard twin-lantern post is usually lower, often 4–6 m, to relate to pedestrians, with shorter symmetrical arms.
The key is that the two heads balance about the column. Because the block is full size, dimension the column height and each arm's reach straight off the elevation, and confirm the two heads sit over the areas they are meant to light — the two carriageways, or the two sides of a boulevard.
Where one twin head pole replaces two
The advantage of a twin head light is that one column lights two areas, which is why it suits central reserves, medians and boulevards. In a road section, a single central-reserve twin head pole lights both carriageways, halving the number of columns compared with single-arm lights on each verge. On a boulevard, twin-lantern posts down the centre or along both edges give a formal, rhythmic streetscape.
Insert the block at the centreline or boulevard line, then ARRAY it along the run at the design spacing. Because both heads are carried on one block, the array stays simple — you are placing one symmetrical unit rather than coordinating two separate columns. Keep the lights on their own layer so the road and lighting can be shown independently.
Inserting and aligning the twin head pole
The DWG is drawn in millimetres. Insert at scale 1 in a millimetre drawing, 0.001 in a metre drawing, or set INSUNITS to millimetres so an imperial template rescales it. Run INSERT or drag from a palette and pick the insertion point at the base of the column, on the central reserve or boulevard line, so the pole stands symmetrically.
Because the heads are balanced about the column, alignment is mostly a matter of placing the base on the centreline and rotating so the arms run across the road or along the boulevard as intended. ARRAY along the line at the design spacing. As a block reference, a change to the head type or column height flows through the whole symmetrical run from one edit.
Where twin head street lights are used
Twin head lights belong on the larger pieces of public realm: dual carriageways and distributor roads with a central reserve, civic boulevards and avenues, bridges and causeways, large car parks and campus spines, and formal plazas. They appear in road cross-sections, masterplans, landscape drawings and the public-realm sections that present the scheme.
Drawn at the correct height and reach, a twin head pole communicates a wide, formal space in a single symmetrical element, which reads clearly in both elevation and section. Free and licence-clear, the block suits competition and student masterplanning as readily as a coordinated highways and landscape package.
One foundation, two heads: what the drawing must resolve
The economy of a twin head light is that a single column and foundation serve two luminaires, but that also means the one pole has to be sized and founded for the combined load and wind area of two heads on out-reached arms. The drawing is where that is acknowledged: a twin head column typically needs a more substantial base than a single-head pole of the same height, and the layout should leave room for it in the central reserve or median.
Symmetry is the other thing the drawing resolves. For the two heads to light their respective carriageways or boulevard sides evenly, the arms have to be balanced and the column truly central, so placing the full-size block on the centreline and confirming the equal reach of each arm is a real check, not a formality. Where the reserve is narrow, the drawing also has to show the arms and heads clearing the running lanes on both sides. Capturing all of this on a scaled, symmetrical block is what lets one pole confidently replace two.

Questions
Frequently asked
What is a twin head street light?+
A column carrying two luminaires — either two arms reaching to opposite carriageways from a central reserve, or two heads on a symmetrical feature post used along boulevards and plazas. One pole does the work of two.
When would I choose a twin head pole?+
When one column needs to light two areas — both carriageways of a dual road from the central reserve, or both sides of a boulevard — which reduces the number of poles and gives a formal, symmetrical streetscape.
What heights are typical?+
Central-reserve highway twin heads commonly sit around 8–12 m with each arm reaching 1–3 m, while decorative boulevard twin-lantern posts are lower, often 4–6 m. The block is full size, so dimension the exact figures off the elevation.
Will the DWG open in free CAD software?+
Yes. It targets AutoCAD 2004 and later and opens in AutoCAD, AutoCAD LT, BricsCAD, DraftSight and free DWG viewers including Autodesk's online viewer.
