Do these use factory mounting points or do I need custom brackets?

They mount at the factory corner locations — no drilling, no brackets, no custom work needed. It's a straight swap with your OEM lights.

Will these still function as signal lights?

Yes. The smoke tint darkens the appearance when off, but the amber signal still shines through when activated. You're not losing function for the look.

What tools do I need to install these?

Basic hand tools — you're removing a few fasteners and unplugging the old lights, then reversing the process. No special equipment required.
