Sourcing vehicle lights and horns from China

Duty at 2%

Read from the UK Trade Tariff on 25 September 2026, bicycle lighting, other vehicle lighting and signalling equipment, sound signalling equipment including car burglar alarms, windscreen wipers, defrosters and demisters, and their parts carried 2% duty on goods from China, with no anti-dumping measure. Listed items have 0% suspensions to the end of 2028: door-mirror heating foil (8512 40 00 10), a piezo parking-sensor buzzer for vehicle manufacture (8512 30 90 20), a listed piezo horn assembly and vehicle information screen, and, under authorised use, a listed fog lamp and burglar alarm sounder; ordinary lamps and horns stay at 2%.

Bulbs and LED light sources on their own are classified with lamps and light sources, not here; confirm the commodity code for each part. For halogen bulbs, see our tungsten halogen lamps sourcing guide.

Approval marks

Schedule 4 of the Road Vehicles Lighting Regulations 1989 requires a dipped-beam headlamp on a motor vehicle first used on or after 1 April 1986 to carry an approval mark or a British Standard mark, and the other schedules set marking rules for other lamps. For road-use lamps, ask for the approval certificate behind each mark and check it on the sample.

Lamps sold for off-road, show or trailer use need their own honest labelling, and UK product safety law still applies.

LED retrofits and the MOT

The MOT inspection manual lists a light source and lamp that are not compatible as a major defect, which covers halogen headlamps converted to HID or LED bulbs. Complete replacement headlamp units built for HID or LED are not caught. Describe retrofit bulbs accurately, and prefer complete approved units.

Vehicle electronics also need to avoid radio interference; ask for EMC test reports.

Worked duty example

For a made-up shipment of 5,000 pairs of LED trailer rear lamps under 8512 20 00 90, add the £3,000 of freight and insurance to the £40,000 free-on-board price and customs sees £43,000. At 2%, duty on these vehicle lamps is £860; import VAT of £8,772 is 20% of the value with duty added. Together that is £9,632, but a VAT-registered importer usually gets the VAT back. A few narrowly described fog lamps, vehicle displays, horns and alarms have their own 0% suspensions, some under authorised use, so check the footnotes if your product is close to one. The duty and VAT guide walks through the calculation.

Inspection checklist

Approval marks: UN Regulations 148 and 149 cover light-signalling and road-illumination devices and UN Regulation 28 covers audible warning devices. Check the E-mark and approval number on each lamp lens and horn against the approval certificate and its communication form, for the exact model supplied.

Beam and sealing: measure the beam pattern of sampled headlamps on a photometric screen or goniophotometer against the approved values, and test sealing to the IP code in IEC 60529 claimed for the lamp, then check for water and condensation inside after the test.

Electrical and EMC: power sampled LED lamps across the vehicle's operating voltage range and check for flicker and failure, ask for the UN Regulation 10 electromagnetic compatibility approval or test report, and check connectors, cable length and pin-outs against the vehicle drawing.

What goes wrong

Vehicle lamps fail on sealing, beam and marking. Housings that are not sealed let water in and condensation builds behind the lens, LED drivers fail early from heat or voltage spikes, and lenses yellow or craze under ultraviolet light. Headlamps with a poor cut-off dazzle oncoming drivers, approval marks appear on lamps that were never approved, and LED units cause radio interference or bulb-failure warnings on modern vehicles.

Check each approval mark against its certificate, run a water spray or immersion test on samples, measure the beam pattern of headlamps on a screen or beam setter, power cycle LED lamps at high and low voltage, fit samples to the target vehicles to check for warnings and interference, and ask for EMC test reports before the order.

Fit and inspection

Give the supplier vehicle models, connector types and mounting points, and fit samples to the vehicle. At inspection, check beam pattern, sealing, connectors and marks.
