Before selling a vehicle, make a record of accessories you added: what each item is, where it is fitted, how it is operated and whether it is included in the sale. Keep the relevant instructions and installation records together. The next owner should not have to guess which lights came with the vehicle and which were fitted later.
This is a documentation guide, not advice on removing wiring or modifying safety systems. Use qualified help when an accessory needs electrical or mechanical work.
Walk around the vehicle with a short checklist
List added lighting, storage items, chargers, decorative pieces and other accessories. Photograph each one in place and record its product name or model where available. Separate the vehicle's original equipment from additions you can actually identify.
Do not assume a branded logo means an accessory was supplied or approved by the vehicle manufacturer. Keep the original order information if it identifies the seller and product clearly.
For example, Car Interior LED Lights and a Wireless BMW Door Step Light are separate catalog products with different information to record. Their names alone do not establish compatibility with every model from a named manufacturer.
Record how each accessory is used
Keep the supplied instructions, control details and any installation paperwork. Note where a removable remote or other component is stored. Do not write your own wiring instructions from memory or advise the buyer to improvise a power connection.
If an accessory uses an app or account, consult its official instructions for transferring or removing personal access. Do not hand over personal passwords as a substitute for the proper reset or transfer process.
Remove personal data through the relevant manufacturer's process and confirm the result before handover.
Decide what is included before writing the listing
Make a clear included-or-removed decision for each accessory. If something is not part of the sale, state that plainly and arrange safe removal through an appropriate professional when needed.
For an item such as the Wireless Mercedes Door Light, document the exact item rather than using a broad phrase such as “upgraded lighting.” A specific description reduces misunderstanding about what the buyer will receive.
Do not claim an accessory increases vehicle value or performance without a sound basis. Present what is actually fitted and its documented condition.
Address faults rather than hiding them
If an added item is loose, damaged or behaves unexpectedly, have it assessed before handover. Do not cover warning indicators or remove parts of a safety system to make the car appear tidier.
Follow applicable sale and disclosure requirements in your location. When unsure, seek qualified local advice rather than assuming that a private sale removes all responsibilities.
Keep any repair or removal invoice with the accessory record so the work is clear.
Give the next owner one useful handover pack
Combine product instructions, installation records and the included-items list with the vehicle's other documents. Demonstrate accessories only when it is safe to do so, with the vehicle parked and according to their instructions.
A good accessory record is short, specific and honest. It tells the next owner what is there, how to find the proper instructions and what work has been done—without expecting them to reverse-engineer your changes after they drive away.
