One-Stop Headlight Retrofit Sourcing Checklist for Dealers
Nov 06, 2026
Short answer: dealers who buy lenses, bulbs, frames, decoders and tools from separate factories spend more time on fitment disputes than on sales. A one-stop headlight retrofit factory sourcing checklist forces every line on the purchase order to match the same vehicle job: bi-LED projector lens size, LED bulb base when needed, vehicle-specific adapter frame, CANBUS decoder, dust cover, shroud and workshop tools. ShinVea, a Guangzhou car light retrofit manufacturer founded in 2015, lists those categories on shinveagroup.com so one carton can leave as a ready job box?or as a headlight retrofit fast installation kit when the vehicle already has a matched listing.

Vehicle-specific adapter frames belong on the same PO as the lens.
Why a sourcing checklist beats a parts catalogue
A catalogue answers ?what do you sell?? A checklist answers ?what must travel together so the installer finishes the car today?? Distributors who skip it usually see four repeat problems:
The lens arrives without the bracket that fits that year?s headlamp.
The decoder base does not match the car?s original socket.
The dust cover is the wrong diameter, so moisture returns in a week.
The shop opens sealed headlamps without an oven or glue plan, then blames the lens.
None of those failures are fixed by a higher wattage claim. They are fixed by locking the bill of materials before the factory packs the carton.
The five building blocks dealers should bundle
Start from the group product map and treat the following as one job, not five unrelated purchases.
1. Bi-LED projector lens (size first)
Most daily jobs use 3.0, 2.5 or 1.5 inch modules on the bi-LED projector lenses category. Decide plug-and-play versus cut-in before you talk about power. Fog upgrades use the fog projector lens line and need their own brackets. Write the lens size and install path on the PO so packing cannot mix a cut-in module with a plug-in frame.
2. LED headlight bulb (only when the programme needs it)
Some dealers run a dual path: projector kits for full upgrades and LED bulbs for customers who stay in the original reflector. The group site lists LED headlight bulbs; deeper platform and base guides sit on the sister site shinvealed.com LED headlight bulbs. Do not put bulbs in the same kit carton as a projector job unless the shop asked for both?keep SKUs separate so warranty claims stay clear.
3. Adapter frame by car model
Universal lenses only sell when shops can mount them. Browse adapter frames by car model. Order by make, model, year and original headlamp type, not by lens wattage. The category also includes plates for common OEM projector formats such as Hella and Koito style housings. Fog brackets sit in a sister category when bumper openings need their own plate.
4. CANBUS decoder matched to the original base
After the lens sits in the housing, the car still has to stay quiet on the dashboard. Stock CANBUS decoders by the vehicle?s original bulb base?H7, H4, H11, 9005 and D1S/D3S where xenon cars remain. One wrong base creates flicker tickets that look like ?lens quality? problems.
5. Sealing, finish, tools and fast kits
Finish the job box with lens shrouds when the customer wants a finished look, dust covers in the 55?95 mm range, wiring harness lines when high-power builds need dedicated feed, and retrofit tools plus headlight oven equipment for shops that open sealed lamps. When the vehicle already has a matched ShinVea listing, use a fast installation kit so lens, frame and related parts pack as one job.

How dealers usually stage the first factory order
You do not need every category on day one.
Stage A ? Core job boxes. Pick your top ten vehicles. For each, lock lens size + adapter frame + matching CANBUS + dust cover. Prefer a listed fast installation kit when the model already exists; otherwise build the same lines as loose parts on one PO.
Stage B ? Workshop enablement. Add tools and oven capacity only for partners who open sealed headlamps. Dealers who only sell to plug-and-play shops can skip that capital until volume justifies it.
Stage C ? Dual path. Add LED bulb bases for reflector upgrades and fog lens + fog bracket pairs if bumper upgrades sell in your market.
Stage D ? Reorder rhythm. Reorder frames and decoders with the next lens shipment so brackets never sit in a separate courier bag. Split freight is what erases margin on a two-lens job.
Commercial notes that belong on the same checklist
Founded 2015 in Guangzhou; brand on the carton is ShinVea.
Warranty: 12 months on ShinVea products (confirm the covered lines on your quotation).
Samples: free samples for distributors; the buyer pays shipping.
OEM / ODM: custom logo and packaging where the category allows.
Agents: ShinVea runs a one-distributor-per-city approach in many markets?ask the sales desk for territory rules.
Prices are quoted after inquiry and are not published on the website.
For deeper lens cut-off and size rules when you export to MEA, LatAm or Indonesia, confirm cut-off on the lens sister site, then pull frames, decoders and tools back onto the group PO so one factory still owns the carton.
What ?one-stop? should mean in writing
Ask the factory to confirm, in the quotation reply:
Every line ships under one packing list and one warranty channel.
Frames are coded to make/model/year, not only to lens diameter.
Decoder SKUs are listed by original bulb base.
Dust cover size is stated in millimetres.
Fast installation kit contents are itemised when you choose a kit SKU.
Tools are optional add-ons, not forced into every carton.
If any of those six points is missing, you are still buying a parts catalogue?not a dealer-ready sourcing process.
Contact the factory desk. Chat with ShinVea on WhatsApp or email [email protected] with your vehicle list, lens sizes, decoder bases and whether you want loose parts or fast installation kits.
FAQ
What should a one-stop headlight retrofit factory order include?
At minimum: the bi-LED lens size you need, the vehicle-specific adapter frame, a CANBUS decoder for the original bulb base, and a dust cover that seals the housing. Add shrouds, harnesses, tools or a listed fast installation kit when the shop?s job card requires them.
When should I order a fast installation kit instead of loose parts?
Order a kit when the vehicle already has a matched ShinVea listing and your installers want one packing list per car. Use loose parts when you serve many models and prefer to mix frames and decoders across a shared shelf.
Do I always need LED bulbs in the same order as projector lenses?
No. Keep bulb upgrades as a separate programme unless a customer asked for both. Projector kits and reflector bulb upgrades have different install paths and warranty conversations.
How do I avoid wrong adapter frames?
Write make, model, year and original headlamp type on every line. Do not order frames by lens wattage alone. Confirm Hella/Koito-style plates only when the housing still uses that OEM projector format.
Are samples available before a first wholesale order?
Yes. Free samples are available for distributors; the buyer pays shipping. Test fitment and decoder behaviour on the cars you sell most before you lock artwork.
Can one factory supply lenses, frames, decoders and tools together?
Yes. That is the point of the checklist: ShinVea lists those categories so dealers can place one enquiry covering the full job box instead of coordinating three suppliers after a failed install.
