The Part That Fails Quietly Until It Doesn't
Degradation here is usually gradual — a slightly dimmer beam, a faint flicker on start-up — right up until the moment it isn't gradual anymore and you're left with one working light on a dark road. Catching the early signs saves a roadside scramble later.
OEM Part Number: confirm via VIN — aftermarket LH Valeo 450804 / RH Valeo 450805
| Passenger side (LH / nearside) headlight — aftermarket | Valeo 450804 (halogen design with LED functions, with DRL, smoke-grey indicator); Van Wezel 5711985 (matrix LED, with DRL, electric levelling, not for facelift); Van Wezel 5711983 (matrix LED, with DRL, electric levelling, black frame, not for facelift); Van Wezel 5711981 (matrix LED, with DRL, electric levelling, chrome frame, not for facelift); Diederichs 2218285 (matrix LED, electric levelling, black, no LED control unit) |
|---|---|
| Driver's side (RH / offside) headlight — aftermarket | Valeo 450805 (pair to 450804, halogen design with LED functions, with DRL); Diederichs 2218980 (LED, with DRL, electric levelling); Van Wezel 5711982 (matrix LED, with DRL, electric levelling, not for facelift); Van Wezel 5711984 (matrix LED, with DRL, black frame, not for facelift); TYC 20-19137-06-2 (LED, with DRL, electric levelling, black, no DRL control unit); Diederichs 2218284 (matrix LED, electric levelling, black, no LED control unit) |
| Bulb types | indicator PWY24W on the halogen-design and LED base units; otherwise LED units |
| Genuine (OE) numbers quoted | None quoted in catalogue listings — order genuine units against your VIN |
| Fitment notes | Basic units use a halogen-style housing with LED functions and PWY24W indicator, while higher trims use LED or matrix LED; the Van Wezel matrix units are marked as not for the facelift, and no true xenon unit is listed. |
IQ.Light matrix LED headlights, where fitted, are a significantly more expensive and technically complex part than the standard LED units, with individually controllable LED segments for adaptive high-beam. Confirm which headlight type your car has (check your original build sheet or ask a VW dealer using your VIN) before pricing up a replacement.

Volkswagen Golf Headlights: What They Do
Later generations of this model use full-matrix LED headlights that individually control dozens of LED segments to shape the beam around oncoming traffic automatically. It's a genuinely clever system, but one with more that can go wrong than a simple halogen bulb.
Volkswagen Golf Headlights: Generations, Derivatives & Headlight Type
| Mk7 (2012–2019), standard trims | Halogen as standard, with Bi-Xenon offered as an upgrade depending on trim and options |
|---|---|
| Mk8/Mk8.5 (2019–present), standard/S trims | "Entry" LED — reflector-style LED illumination, though turn signals remain incandescent bulbs rather than LED |
| Mk8/Mk8.5, SE/Autobahn trims and above | Full "IQ.Light" LED — projector-style with genuine full LED illumination including LED turn signals, sharper beam pattern, static cornering lights, and Matrix beam support where enabled; genuinely not interchangeable with the Entry LED units without also swapping the wiring harness |
| GTI | Red LED daytime running light accent strip, distinguishing it at a glance from other trims |
| Golf R | Blue LED daytime running light accent strip instead of GTI's red — otherwise shares the IQ.Light hardware |
| Market note | European-spec "IQ.Light" units support full Matrix beam functionality (selectively dimming parts of the main beam to avoid dazzling other drivers); North American-market Golf R/GTI headlights are hardware-limited and don't enable this by default, a genuine market-specific restriction rather than a fault |
