Will these reflectors work on an M3?

No — these are designed specifically for the standard 3 Series and won't fit M3 bumper configurations. Check your bumper fitment before ordering.

Do these come with bulbs or wiring?

These are passive reflector units only — they're a direct visual swap with no bulbs, wiring, or electrical components involved.

Can I install these myself?

Mounting method not specified — test-fit before committing to adhesive or fasteners. Most reflector swaps use factory clips or bolts at the bumper attachment points.
