This is a replacement lens for the cab roof marker or clearance lights commonly found on Mack trucks.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
The lens covers the bulb to protect it from weather and road debris while maintaining the required light signal. Over time, the original lens can crack, fade, or become cloudy, so replacing it restores proper visibility and DOT compliance. It is a direct-fit, snap-on or screw-on plastic lens designed to match the original equipment shape and size.
