For G20 and G21 3 Series (2019-2022) with factory adaptive LED headlights - not laser, not halogen, not pre-facelift - this is the yellow DRL module set that swaps in cleanly, no coding, no CAN bus errors, no guesswork.
Works only on G20/G21 with adaptive LED headlights - if your car has base LED or laser units, this won’t fit or function
Part number 63119348721 - matches BMW’s own part ID for the yellow variant; cross-checks against EVO, BimmerTech and BimmerCode-compatible setups

No ‘OEM replacement’ framing - this is a functional colour-change module, not a repair part. It doesn’t fix flicker, error codes or headlight alignment. It makes your DRLs yellow. Because race car.
