Will these work with my factory turn signal bulbs?

Yes—these mount the same way your stock corners do, so your existing bulbs fit directly. Just transfer them over during installation.

Do I need to remove the fender or bumper to install these?

No. Access is from the top of the fender at the corner seam. You'll need a screwdriver and socket set, but fender removal isn't required.

Can I return these if they don't fit?

Standard return process applies—if fitment issues come up after you test-fit them, contact ModSupply support with photos and we'll sort it out.
