Will the smoked lens affect signal visibility or legality?

Smoke-tinted signal lenses still transmit amber light effectively—the tint just darkens the appearance. Stock out of the box; check your local traffic codes if you're concerned, but these are street-legal in most regions.

Do these come with bulbs and wiring harnesses?

Just the light housings. Your existing bulbs and harnesses transfer over from the factory lights—no additional parts needed.

How do I know these will fit my specific year?

Fitment is confirmed by the product page you're on. If you're unsure, verify your year/make/model in the Convermax filter at the top—it'll show green if these are right for your truck.
