Do I need any brackets or fasteners beyond what's included?

The assembly uses factory mounting points, so you'll use your vehicle's original hardware. Have your fastener kit handy when you pull the old lights — reuse what you've got.

Will the smoked lens affect brightness or beam pattern?

Smoked lenses reduce output slightly compared to clear, but the H10 bulb is sized for fog light function and will still cut through rain and low visibility. Output is compliant and safe for road use.

Can I install this myself, or do I need a shop?

Fog light swap is straightforward — pop out the old assembly, disconnect the bulb, and bolt the new one in using factory points. You'll need basic hand tools and maybe 20 minutes per side. No special tools required.
