Checked by FitsMyCar against the sources above · how we check
Can you fit LED bulbs to the Fabia Mk3?
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 Skoda Fabia Mk3 take?
H4. Base S/SE reflector lamp = H4 (dip+main). SE L / Monte Carlo projector lamp = H7 dip. No xenon on UK cars. Facelift keeps same two options.. 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 as dip on S/SE; projector units use a separate H7 main beam (4 x H7 per car)..
Did the Fabia Mk3 change bulbs at the facelift?
Dip beam (low): H4. Base S/SE reflector lamp = H4 (dip+main). SE L / Monte Carlo projector lamp = H7 dip. No xenon on UK cars. Facelift keeps same two options.
What if my Fabia 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 Fabia'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 Skoda Fabia Mk3 use?
P21/4W. Upper cluster P21/4W brake+tail; lower P21/4W fog+tail; plus 2 x W3W tail fillers per side. Not P21/5W. High-level brake LED non-replaceable.. Separate bulbs on this car.
