Rigid light that fits the host
When a standard linear module misses the fixing points, diffuser or electrical connection, VST develops custom light bars for the host. As a custom light bars manufacturer, we include both end details and the protected feed in the sample, so you can check the complete bar in place.
Send a host photo, approximate bar length or existing module; incomplete details are fine for the first discussion.
A rigid bar is useful when the host leaves little room for wiring or adjustment. As a custom light bars supplier, VST builds the module to the fixing and power interfaces you provide; the cabinet, shelf or machine remains the supporting structure.
Purchasing risk: The bar cannot be fastened without drilling or redesign.
Confirm: Fixing centers and usable face
VST solution direction: The actual fixing envelope is included in the drawing.
Purchasing risk: The lead may be pinched or left exposed after assembly.
Confirm: Exit side and mating cable route
VST solution direction: The entry is moved to an accessible protected path.
Purchasing risk: The task remains poorly lit despite an operating LED bar.
Confirm: Target plane and mounting angle
VST solution direction: The bar position and diffuser are checked in the host mock-up.
Purchasing risk: Longer or enclosed runs may heat nearby material.
Confirm: Host airflow and operating condition
VST solution direction: Thermal checks use the actual mounting and duty cycle.
At our custom light bars factory, an existing aluminum profile is adapted when its length, lens and ear geometry can meet the host. New profile or end tooling is considered when the available platform cannot seat safely or conceal the connection.
An existing extrusion can be cut and populated for the host. A new section is possible when a different diffuser seat, heat path or external outline is essential.
Buyer input: Occupied space and visible edge
Board layout, diffuser finish and shielding can follow the distance to the task surface. Higher output also changes heat and power demand.
Buyer input: Target task plane and appearance
Ear positions, slots, clips and fasteners can be coordinated with the host without assuming the host structure is supplied.
Buyer input: Fixing faces and assembly access
Protected exit side, lead length and mating connection can be defined for the host wiring route. A sealed or quick-disconnect joint requires the matching system.
Buyer input: Supply and mating connector
If an existing extrusion accepts the required diffuser and mounting, adjust its length. A new section is reserved for a different heat path, optical seat or fixing shape.
| Decision factor | Adapted Existing Profile | New Bar Section | Buyer guidance |
|---|---|---|---|
| Frame geometry | Available aluminum section with adjusted cut | Dedicated section for the host outline | Use the host envelope and fixing face to choose. |
| Diffuser fit | Existing seat and compatible rigid cover | Seat formed around a new optical requirement | See the full assembled face at the normal view. |
| Mounting ears | Localized ear or clip changes | Integrated fixing feature in the new profile | Compare assembly access before finalizing holes. |
| Tooling exposure | Usually lower if stock parts suit the host | May require an extrusion or molded end tool | Request a tooling line in the proposal when needed. |
| Repeat control | Versioned cut, board and lead list | New section plus versioned mating parts | Both routes need one released bar definition. |
As a custom light bars manufacturer, VST draws the full bar envelope with its mounting ears, end caps and cable exit. The assembled sample shows whether those parts fit the host and place light on the intended task.
VST work: Place the proposed bar and ears against the host section.
Stage output: A bar outline and fixing reference.
VST work: Position the board, diffuser and protected cable entry in the profile.
Stage output: An assembly layout with accessible ends.
VST work: Fit the closed bar into the host and inspect task coverage.
Stage output: A representative installed sample.
VST work: Record profile, board, cover, fasteners and connection version.
Stage output: A controlled drawing and component list.
As a custom light bars supplier, VST checks the assembled bar against the host interface, then measures the electrical and thermal behavior of the powered sample. Optical checks are chosen for the light task and diffuser.
Purpose: Verify the proposed supply and connection path.
Method: Connect the complete bar to a suitable source and meter with both conductors accounted for.
Acceptance criteria: Operation matches the agreed electrical interface.
Evidence: A source and connection check sheet can be supplied for the complete bar sample.
Purpose: Characterize light and color if required.
Method: Mount a suitable unlit bar inside the open sphere and route its cable through a feed-through before closing the door.
Acceptance criteria: Compare actual measurements with the released optical target.
Evidence: An optical measurement sheet is available after a completed test on the chosen bar.
Purpose: Check the extrusion and connection end under load.
Method: Operate the mounted bar and observe defined surface points with a thermal camera or probes.
Acceptance criteria: Recorded temperatures stay within the agreed component and host limits.
Evidence: Recorded extrusion and end temperatures can accompany the host-mounted bar sample.
Purpose: Prevent mounting or plug mismatch.
Method: Use a fixture and caliper on the ears, length, exit and mating interface.
Acceptance criteria: The assembled bar fits the accepted host reference.
Evidence: The fixture results can be recorded against the accepted host interface.

An existing bar profile with light changes normally begins at 500 units for a single model. A dedicated housing section or substantial light-engine redesign generally starts at 1,000 units. Length and connector variants are listed separately in the quote.
VST can make a complete bar sample to check mounting, light and connection. Processing charges apply; a dedicated extrusion or molded end can add tooling cost. A future order may recover eligible sample charges through refund or credit when the terms are documented.
The sample window is typically 15–25 working days for a light adaptation and 30–50 for deep development. Corresponding production windows are 20–30 and 25–35 working days. The period starts after the interface is defined and applicable payment conditions are met.
A new aluminum section, end cap or installation fixture can require NRE or tooling. An eligible mold or tool charge may offset a later production payment where the qualifying order, amount and method are agreed in writing.
A stable run lets VST prepare the profile, board and connectors ahead of later batches. The released bar specification keeps those parts consistent, while material reservation follows an agreed forecast. Finished bars are produced for the order.
Packing protects straightness, diffuser faces, fixing ears and cable exits. VST can specify cartons and protective inserts by bar length, with the requested product labels, instruction sheets, carton marks, manuals, barcodes and brand artwork. Freight terms follow the final order.
Custom light bars can switch on at the bench and still miss their task once fixed inside a cabinet or machine. Ear positions, wiring access and the diffuser view need to be checked in the host. The quote should state which fasteners and electrical parts travel with the bar. For later replacements, each length and connector variant needs an identifiable build reference.
Often, yes, when the profile has enough space for the board, diffuser and heat path. A new section is considered only if the host envelope or attachment cannot be met.
The quote identifies the module and any agreed fasteners, lead or mating connector.
| Interface | Define for the order |
|---|---|
| Fixing | Ear or clip supplied with the bar |
| Power | Lead, connector and external supply boundary |
| Diffuser | Finish and replacement access |
Yes if its electrical rating, polarity and mechanical mating are suitable. A sample with the real mating half is the fastest way to rule out a fit error.
Only when the fixing surfaces, ear spacing, heat path, connector and service access are compatible. VST can retain a common light engine while changing the bracket or lead for each host.
Each length, board population, connector and end detail receives an identified version in the production list. The host can then be matched to the correct replacement bar.
