The 8V is the A3 built 2012–2020. The registration's age identifier is the quickest check: 12 to 70 plate. The V5C gives the first-registration date, and this generation's fitments apply from the first 2012 cars onwards up to the 2020 run-out.
Main beam (high)H7VerifiedSame H7 bulb doubles as main beam on the halogen reflector unit.
Front fogH8VerifiedH8 on birnen-typ and mk-led.hr A3 8V page; audi-sport 8V owner also cites H8. boslla's H11 claim likely US-spec (US A3 uses H11) or LED kits fitting both bases. Facelift 8V (2016+) S-line/LED cars have LED fogs, non-replaceable.
Sidelight / DRLW5WVerifiedHalogen headlamp sidelight W5W (501). DRL in halogen lamp is H15 (shared with main beam); xenon/LED headlamps have non-replaceable LED DRL.
Front indicatorPWY24WVerifiedOften listed as PY21W. 8V uses PWY24W amber wedge in all headlamp types (halogen, xenon, LED). elsewhere; that is wrong for this car.
Rear indicatorPY21WVerifiedPY21W (581) in outer cluster on halogen rear lamps. birnen-typ also lists RY10W for a variant. LED rear clusters (S-line/later facelift) non-replaceable.
Brake / tailW21WVerifiedOften listed as P21/5W. Brake is single elsewhere — filament W21W (582) in outer cluster; tail is separate W16W in inner (tailgate) unit per Hella 2TZ 012 834 spec. Not a P21/5W twin-filament.
ReverseH6WVerifiedOften listed as P21W. Reverse is H6W (BAX9s) in inner tailgate unit: birnen elsewhere — typ + Hella 2TZ 012 834 / MM 714081090 specs. ledperf (P21W) and ultimatestyling (W21W) are generic/wrong.
Rear fogW21WVerifiedOften listed as P21W. W21W (582) in inner tailgate unit (Hella 2TZ 012 834 lists W16W/W21W/H6W = tail/fog/reverse). birnen elsewhere — typ notes an H21W variant on some units.
Number plateLED (non-replaceable)VerifiedOften listed as W5W. 8V number plate lamps are sealed LED units as standard (birnen elsewhere — typ: LED; ledperf sells replacement LED modules by year, not bulbs).
