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 i30 GD take?
H7. Handbook: 55W H7L or 35W D1S (HID option); agmvision H7 halogen / D1S xenon (D3S on later i30).. Verified — the source is shown on the card above.
Is the main beam the same bulb as the dipped beam?
Yes — one H7 does both on this car. Handbook: 55W H7L high beam on both halogen and HID cars; agmvision H7 (xenon cars too)..
Did the i30 GD change bulbs at the facelift?
Brake / tail: P21/5W. Often listed as LED (non elsewhere — replaceable). Handbook Type A cluster: stop/tail 21/5W P21/5W; agmvision P21/5W. Facelift Type B cluster has LED stop/tail. High-level brake LED.
What if my i30 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 i30'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 i30 GD use?
P21/5W. Often listed as LED (non elsewhere — replaceable). Handbook Type A cluster: stop/tail 21/5W P21/5W; agmvision P21/5W. Facelift Type B cluster has LED stop/tail. High-level brake LED.. A twin-filament bulb — one bulb does both tail and brake.
