Headlight Retrofit Parts Supplier: What a Complete Kit Includes

Short answer: a headlight retrofit job needs more than a projector lens. A complete kit is the bi-LED lens plus a vehicle-specific adapter frame, a lens shroud, the right CANBUS decoder or driver, wiring and plugs, a sealed dust cover, and the workshop tools to open and reseal the headlamp. Sourcing all of it from one headlight retrofit parts supplier cuts fitment problems, shipping costs and supplier management. ShinVea, a Guangzhou car light retrofit manufacturer founded in 2015, supplies every one of these categories for distributors and retrofit shops.

Vehicle-specific adapter frames hold the projector lens in the original headlamp housing.

Why distributors buy retrofit parts from one supplier

Most returns in the retrofit trade are not caused by a faulty lens. They come from a bracket that does not match the headlamp, a missing decoder that triggers a dashboard warning, or a dust cover that lets moisture in. When the lens, frame and accessories come from different factories, nobody owns the fitment.

A one-stop supplier solves three problems for a distributor:

• Fitment is checked as a set. The lens size (1.5, 2.5 or 3.0 inch) decides which adapter frame, shroud and dust cover you need.
• One consolidated shipment. Small, light accessories ride in the same carton as the lenses instead of paying their own courier fee.
• One contact for after-sales. If a customer reports flicker or condensation, one team can check the whole kit.

Bi-LED projector lenses: the core of the kit

ShinVea makes bi-LED projector lenses in 3.0, 2.5 and 1.5 inch sizes, plus 2.0 and 3.0 inch fog projector lenses. The 3.0 inch round and square lenses come as plug-and-play (non-destructive) versions with an H7, H4 or 9006 interface, in dual-reflector and single, dual or triple direct-beam layouts. They run at 12 V as standard, with 24 V available on request, and the cut-off can be made for left-hand or right-hand traffic. The lens size you choose decides the rest of the kit, so start here.

Adapter frames: matching the lens to the car

An adapter frame (bracket) is what makes a universal lens fit a specific headlamp. ShinVea's adapter frame catalog is sorted by car model and includes brackets for vehicles such as the Changan UNI-K, Haval H6 2021, Jetour Traveller and Jetour X70 Plus, and Honda Elysion/Odyssey 2022. There are also adapter plates for common OEM projector formats such as Hella 3R and Hella 5. Always order the frame by make, model, year and headlamp type (halogen or factory LED), because one model can use different housings across years.

Fast installation kits for high-volume models

For popular vehicles, a fast installation kit saves workshop time because the parts are already matched. Current kits on the ShinVea site cover models such as the Ford Focus (2012 and 2015–2017), Toyota Land Cruiser Prado (2014–2016 and 2019–2022), Toyota Corolla, Golf 7, Skoda Octavia (2014–2016), Nissan X-Trail (2014–2016) and Hyundai Elantra (2012–2015). For a distributor, these kits are the easiest way to offer a retrofit to shops that do not want to design their own bracket.

CANBUS decoders and control modules

Many cars monitor the headlight circuit. ShinVea's CANBUS category includes decoders for D1S/D1R and D3S/D3R (some with fan cooling), an H4 decoder for bi-laser lens installs that solves the high-current problem on high beam, an H15 decoder, decoders for replacing original bi-LED projector lenses or LED chips, and hi/lo stepper control modules (old Hella type and a universal Bosch type). Ask for the decoder together with the lens so the installer is not stuck on the day of the job.

Shrouds, cables, dust covers and tools

• Lens shrouds for 1.5, 2.5 and 3.0 inch lenses, in chrome or black, with white, red or RGB angel-eye and DRL options.
• Cables and plugs: wiring harnesses, extension cables and sockets for headlight and fog lamp retrofits.
• Dust covers in 55, 70, 80, 85, 90 and 95 mm, plus a waterproof rubber cover with 7 wiring holes.
• Retrofit tools and machines: headlight opening tools, cleaning and sealing tools, ovens and test equipment for workshops.

How to plan a first order as a distributor

1. List your top vehicles. Start with the 10–20 models your local shops retrofit most.
2. Pick lens sizes per vehicle. 3.0 inch for full-size housings, 2.5 inch for compact housings, 1.5 inch for slim lamps and motorcycles.
3. Add a frame or a fast kit for each vehicle. Send the make, model and year; ShinVea confirms the matching bracket.
4. Add decoders where needed. European cars and D-series HID cars are the usual suspects.
5. Add consumables. Dust covers, sealant and cables are cheap to include and expensive to air-freight later.
6. Request samples first. ShinVea offers free samples to distributors; the buyer pays shipping.

Every lens carries a 12-month warranty, and prices are quoted on request after you send the model list.
