Does this LED light mount the same way as my factory unit?

Yes—this unit uses factory mounting points, so no drilling or modification required. Connect to your existing wiring harness and you're done.

Will the black smoke lens pass inspection?

The tint is designed to maintain legal braking visibility while delivering the dark aesthetic. Check your local regulations to be certain, but this style is road-legal in most jurisdictions.

What's the lifespan of these LEDs compared to the factory bulb?

LED units outlast incandescent bulbs by thousands of hours and draw less current from your electrical system. Exact lifespan depends on driving habits and environment, but expect significant durability over stock.
