Will this bolt directly to my vehicle without drilling or modifications?

Yes — these mount at factory rocker and attachment points with no drilling needed. Your existing hardware will work.

Do I need to buy the bulb separately, or does it come installed?

The assembly ships without a bulb. You'll need to source the correct bulb type for your vehicle's specifications and install it yourself.

What's your return window if this doesn't fit?

Test-fit before fully securing — confirm that the left-side unit aligns with your mounting points. Once installed, fitment issues fall outside standard returns. Measure twice, order once.
