|Your heavy-duty truck comes equipped with factory cab lights. However, those lights are often the first to experience the debilitating effects of the weather and sun exposure. They are dry rotted, cracked and discolored. Rather than replacing them with a set of conventional, OEM lights, consider something different. These truck cab lights provide you with the best way to replace existing lights and avoid the ugly fate of those lights at the same time. Created of heavy-duty polycarbonate, they have the strength and durability to withstand the effects of weather and sunlight. That means they will resist fading, cracking and discoloration throughout years of constant use.
