Checked by FitsMyCar against the sources above · how we check
Most trims of this car have halogen headlamps. In the UK, a halogen headlamp unit on a car first used on or after 1 April 1986 must not be converted to LED or HID bulbs: the MOT inspection manual (§4.1.4) treats a converted unit as a fail, however bright or well aimed it is. “Retrofit LED H7” bulbs sold for these cars are for off-road use. Halogen upgrade bulbs (+150% and similar) are legal because the unit is unchanged. Sidelights, indicators and number-plate LEDs are a separate question — E-marked LED versions of those are road legal.
What dipped beam bulb does the Hyundai i20 GB take?
H4. Standard halogen reflector uses H4 (UK 472). Bi-halogen projector variants use HB3 for both beams. No xenon on UK GB.. Verified — the source is shown on the card above.
Is the main beam the same bulb as the dipped beam?
Yes — one H4 does both on this car. Same H4 twin-filament bulb as dip; HB3 on bi-halogen projector variants..
What if my i20 has xenon headlamps?
Cars with factory xenon use a sealed D-series capsule for dipped beam, not the halogen fitting above. Check the printing on the back of the headlamp unit or the handbook page for “D1S/D2S/D3S”.
Can I put LED bulbs in the i20's headlamps?
Not legally in a halogen unit — the MOT inspection manual treats a converted headlamp as a fail. Halogen upgrade bulbs are fine. Details in the legality section above.
What brake and tail light bulb does the Hyundai i20 GB use?
P21/5W. Bayonet twin-filament (380) on cars without LED rear lights; LED rear clusters non-replaceable. birnen-typ also lists W5W tail on LED-cluster cars.. A twin-filament bulb — one bulb does both tail and brake.
