OEM Part Number: confirm via VIN — aftermarket LH TYC 20-14104-05-2 / RH TYC 20-16291-05-2

Accuracy note: Covers the Kia Rio (2017-) as listed in the UK aftermarket catalogues. Headlights are sold by side (passenger / nearside = LH, driver's / offside = RH on a UK car) and by lamp type — halogen, xenon (D1S / D3S) and LED or full-LED units are not interchangeable, and DRL, cornering and levelling options change the part number again. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Check the lamp type and traffic side (UK right-hand-traffic units, not LHD) against your VIN, and expect xenon / LED and adaptive units to need levelling adjustment or coding after fitting.

Passenger side (LH / nearside) headlight — aftermarket	Van Wezel 8327963 (halogen H4, no levelling motor); Van Wezel 8316961 (halogen H4, electric levelling motor); Van Wezel 8316963 (halogen H4, electric levelling motor); Diederichs 6543081 (halogen H4, levelling motor); Alkar 2785999 (halogen H4 with PY21W and W5W, electric); TYC 20-14104-05-2 (halogen H7/H1 with W21/5W, electric levelling motor)
Driver's side (RH / offside) headlight — aftermarket	Van Wezel 8327964 (halogen H4, no levelling motor); Van Wezel 8316962 (halogen H4, electric levelling motor); Van Wezel 8316964 (halogen H4, electric levelling motor); Diederichs 6543080 (halogen H4, levelling motor); TYC 20-16291-05-2 (halogen H4, electric levelling motor); Johns 41 14 10 (halogen H7/H1, DRL with indicator, no motor)
Bulb types	dipped and main H4 (P43t) on most units, H7 or H1 on the twin-reflector units, indicator PY21W, sidelight W5W
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	All units listed are halogen, mostly H4, with only the Johns unit offering a daytime running light. Pick the version with or without a levelling motor to suit the car's equipment.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Kia Rio Headlights

If your Rio has factory-fitted halogen headlamp housings, converting them to fit LED bulbs is treated as a definite MOT failure under the current inspection manual — this isn't a grey area or a minor advisory, since a housing designed for halogen doesn't distribute an LED bulb's light output correctly, which can genuinely dazzle oncoming drivers. If you want a genuine LED upgrade, the correct route is a complete headlight unit designed for LED from the factory, not a bulb swap into an existing halogen housing.

Before you buy: matrix LED, adaptive, and cornering headlight systems often require electronic coding to the car after a unit swap, even for a genuine like-for-like replacement — a headlight that isn't recognised by the car's electronics can trigger warning lights or fail to auto-level correctly. Check whether your specific trim has one of these systems before assuming a straightforward bulb-in, bulb-out job.

Kia Rio Headlights: What It Does

The Kia Rio's headlight unit job is positioning the main and dipped beam bulbs (or LED/matrix modules on higher trims) to light the road without dazzling oncoming drivers. That housing frequently also contains the daytime running light and front indicator, which is exactly why part numbers and repairs here can get complicated.

Standard trims	Halogen as standard
GT-Line/higher trims	LED headlights become available further up the range — genuinely a different assembly and connector from the halogen units on lower trims, not a simple bulb swap
