Do these need any wiring work, or do they plug into the stock harness?

Wiring configuration not specified — you'll want to test-fit and verify connector type before installation. Bring your service manual or contact the Montero community forums for harness routing specifics for your year.

Will the smoked lens reduce light output enough to be a problem at night?

Smoked lenses are designed to balance aesthetics with function — they'll reduce glare and brightness slightly but H11 bulbs are bright enough for safe low-beam work. If you're in heavy fog or night construction zones regularly, run a test drive before committing long-term.

What if one light arrives damaged or stops working?

Check the return window and condition upon arrival — document with photos if there's shipping damage. Contact support with your order number and photos for replacement or return options.
