Will these lights fit my current housing, or do I need a whole new assembly?

These are complete front signal light assemblies. They replace your existing units entirely — no housing swap needed. They bolt directly to factory mounting points.

Do I need to do anything to the lenses before installing?

They arrive brand new and ready to mount. No sanding, priming, or prep work required. Just clean the mounting surface on your vehicle and bolt them on.

Are both bulbs included, or just one?

Both amber bulbs come installed in the assemblies. You're fully outfitted out of the box.
