Yes — this assembly uses the same mounting points as the original equipment. No holes need to be drilled or modified. Existing fasteners and hardware should work.

Do I need to remove the bumper to install this?

Access varies by vehicle configuration. You may be able to reach the assembly from inside the cargo area, or the bumper may need to come off for full clearance. Check your service manual or test-fit first.

Is the bulb included with this light?

Bulb is not included — you'll need to transfer your existing bulb or source a replacement matching your vehicle's specification.
