Do these come with bulbs?

Bulbs are not confirmed as included. Test the housing fitment first, then source bulbs that match your bumper's wiring setup — most RX-7 shops stock direct replacements.

Will these work with my bumper sensor holes?

These are signal lights, not fog or sensor housings. If your bumper has sensor cutouts below or near the signal location, these lights won't fill those gaps — you'll need separate fog light or filler trim pieces.

What's the mounting method?

Factory mounting points are standard for this fitment, but exact bracket or clip details aren't specified. Plan to test-fit before final install and confirm fastener type with your bumper assembly instructions.
