Do these lights have the reflector already integrated, or do I install them separately?

The reflector is a separate piece included in the set. Both the signal lights and reflector mount to the front bumper, so you're installing two components total.

Will the smoke tint affect visibility or brightness at night?

Smoke finish reduces light output slightly compared to clear lenses, but these are designed as a direct OEM replacement, so they meet factory visibility standards. If you're concerned about brightness in low-light driving, test them before committing to permanent install.

Do I need to remove the bumper cover to install these, or can I access them from underneath?

Mounting method isn't specified in our data — you'll want to test-fit or reference your service manual to determine if bumper removal is necessary on your setup.
