Genuine OEM Style LED Headlight Ballast – BMW 2, 3, 4 Series, X5, X6 (PN: 63117434273)

If your BMW’s adaptive LED headlights are acting up or one side has gone dark, don’t buy a whole new assembly.

Grab this OEM-quality LED ballast instead.

It’s a direct replacement for a ton of models including the 2, 3, 4 Series as well as the X5 and X6.

The part number is 63117434273, and it crosses with a bunch of others like 7429127 and 7457875, so double-check yours and you’re golden.

It’s got the DOT stamp, runs on 12V DC, and mounts up just like the factory part.

Comes with a 2-year warranty too, so you know it’s solid.

Clear lenses, black housing—keeps everything looking stock and working perfectly.
