This car has 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 Vauxhall Astra J take?
H7. 55W (477). 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. Often listed as H1 elsewhere — Astra J is twin H7 (H1 was Astra H).
Did the Astra J change bulbs at the facelift?
Front fog: H11. Facelift MY13+; pre-facelift MY10–12 uses H10. If fitted
Can I put LED bulbs in the Astra'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 Vauxhall Astra J use?
P21/5W. Most-listed; W21/5W wedge on some cluster designs. A twin-filament bulb — one bulb does both tail and brake.
