What lights do I need?

Check the specific vehicle requirements or contact Truck-Lite Technical Support. Note that states cannot require anything different than what is in FMVSS-108; however, states can add regulations. Contact Truck-Lite for special situations.

How hard should I tighten down (torque) plastic lights or devices?

Over-torqueing will generally cause cracking or distortion. Use the torque specifications provided by the manufacturer. A marker light will generally be in the neighborhood of 8 to 20 inch lbs., but a good rule of thumb is to use the minimum torque necessary to secure the device.

I'm painting my vehicle, what if I get some paint on the lens?

You should be careful to avoid getting paint on the lights; most paints (excluding water based) are incompatible with polycarbonate lights. They may also cause wires or cable insulation to crack.

What's the difference between an acrylic and polycarbonate lens?

Given its weather resistance and clarity, acrylic has long been the most widely used material for lenses. However, polycarbonate is much less likely to shatter, chip or crack upon impact and can withstand higher exposure to heat. Polycarbonate lenses are given a special coating to improve abrasion, UV and chemical resistance; still, to prolong the life of your lenses, it is recommended that you only clean them with a mild detergent and soft cotton cloth.
