Replacing aircraft lights with LEDs: function, voltage and approval documents
Compare aircraft LED lighting by function, exact P/N, voltage, mounting and documentation. Prepare a complete replacement enquiry before ordering in Israel.
Ask about this requirementThe quick answer
Identify the existing light and its job before comparing LED replacements. Landing, taxi, position and anti-collision lights are not a single interchangeable category. Keep the full P/N and voltage information, then have the aircraft-specific installation basis and any required kit reviewed. A lamp that fits the opening or looks brighter does not by itself establish an eligible replacement. Ask for the complete package, including any separate connector, mounting or power-supply changes.
Illustrative example — not a real customer case
A worked purchasing example: Price the reviewed lighting package
An illustrative owner requests an LED upgrade using only a photograph of an old round light. Two supplier candidates have different voltage variants and different kit contents.
What to include
- Identify the old assembly, actual role and recorded aircraft supply requirements.
- List each proposed exact P/N with included hardware, any separate power unit and installer-required documents.
- Compare the complete reviewed packages and delivery dates rather than the price of the visible lamps alone.
What this resolves
The customer can assess comparable offers without treating an unreviewed lamp as an approved installation.
Begin with the light's actual function
Describe where the light is installed and what it does, using the aircraft records and the existing assembly P/N. Include the aircraft make/model and any known modification reference. A position light, an anti-collision light and a landing or taxi light have different intended functions; colour alone is not sufficient identification. Manufacturer catalogues may show several related assemblies under a common family name. Keep left/right, colour and variant references separate where relevant. An accessible overall photograph and a readable label often resolve more than an informal description such as 'the small wing light'.
Compare the complete electrical and mechanical package
Record the stated supply voltage, connector or accessible wire identification, mounting arrangement and any separate power unit that forms part of the existing system. Some replacement families have distinct voltage-specific P/Ns; another product may have a stated wider operating range. Read the exact model data instead of generalising from one example. Ask the installer which components remain and which are replaced. A lower published current draw does not automatically mean every existing circuit, controller or installation detail is suitable. Request a clear included/excluded list for hardware, adapters, lenses and kits.
Review documentation before accepting the offer
Ask the responsible maintenance or installation organisation which current manufacturer instructions and aircraft-specific approval basis apply. Product approval wording and installation eligibility are separate questions. A published cross-reference can help identify a candidate, but it should not silently replace the requested P/N. When alternatives are offered, compare their exact references, required accessories, documentation and lead times in separate lines. For urgent replacement in Israel, add the required date and contact details; availability and scope are confirmed in the offer rather than assumed from a catalogue image.
What to compare
| Requirement | Compare | Common omission |
|---|---|---|
| Function and position | Landing/taxi, position or anti-collision role | Choosing from colour or appearance |
| Exact P/N and voltage | Variant-specific manufacturer data | Dropping a voltage or colour suffix |
| Installed package | Mounting, connector and separate power unit | Quoting only the visible lamp |
| Applicable documents | Aircraft-specific installation review | Assuming a product approval covers every installation |

Common mistakes to avoid
- Treating every LED lamp as a direct replacement
- Comparing brightness while omitting voltage and function
- Approving a candidate cross-reference before aircraft-specific review

Common questions
Does a published direct replacement claim settle the entire installation?
It helps identify the manufacturer's intended candidate. The exact product, aircraft configuration, instructions and applicable installation basis still need review by the responsible organisation.
Should the quote include a separate power supply?
Describe the existing system and ask which items are retained, replaced or supplied separately. Do not assume that an old power unit and a new LED assembly work together.
Can you quote from the old lamp photograph?
A photograph is a useful start. Add the aircraft details, existing P/N and voltage if available; we will clarify any missing configuration before confirming the package.
