This is a replacement lens for a Betts heavy-duty truck or trailer light.
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.
It is designed to fit specific Betts series lamp housings, acting as a durable, weather-resistant cover that protects the bulb or LED insert while allowing the correct color of light to pass through. Lenses like this one typically need to be replaced when they become cracked, faded, or broken from road debris or impact, which can lead to moisture intrusion, bulb failure, and a violation of lighting safety regulations. Swapping the old lens for a new one restores the light's full brightness and keeps the electrical components sealed and secure.
