Do I need to remove the bumper to install these?

No — these bolt directly at the factory mounting points. You can swap them without dropping the bumper, though some prefer to do it while removed for easier access.

Will the smoke lens still light up properly?

Yes. The tint darkens the appearance when off, but the bulb brightness shines through when the signal is active. You'll see a darker amber glow instead of bright amber.

Are the bulbs included?

Bulbs are not included — you'll transfer your existing bulbs from the stock housings or source replacements separately.
