The Mk5 is the Golf built 2003–2008. The registration's age identifier is the quickest check: 03 to 58 plate. The V5C gives the first-registration date, and this generation's fitments apply from the first 2003 cars onwards up to the 2008 run-out.
Main beam (high)H7VerifiedH7 on both halogen and xenon headlamps (bi-function on xenon)
Front fogH11VerifiedH11 on cars built to 01/2007; facelift-era cars from 01/2007 use HB4. Check bulb before buying. Split per birnen-typ, base H11 also on agmvision and xenons-online Mk5 page.

Rear indicatorH6WVerifiedUnusual fitting: small H6W bayonet behind an amber lens section, not PY21W. Hella/TYC Golf V rear-light unit specs list lamp types P21W + H6W, and agmvision names H6W for the rear turn signal.
Brake / tailP21WVerifiedSeparate single-filament P21W for brake and a second P21W for tail - NOT a combined P21/5W. Confirmed by agmvision (brake P21W, rear position P21W) and Golf V rear lamp unit specs.

Rear fogP21WVerifiedP21W, in the bootlid inner lamp. Corrects micksgarage's R10W, which no other source supports; birnen-typ and agmvision both give P21W.
