People’s lives depend on your safe installation of Federal Signal products. It is important to read,
understand, and follow all instructions shipped with this product. Listed below are some other
important safety instructions and precautions you should follow:
• To properly install a light assembly, you must have a good understanding of automotive electrical
procedures and systems, along with proficiency in the installation and use of safety warning
equipment.
• A light system is a high current device. In order for it to function properly, make a separate ground
connection. If practical, connect it to the negative battery terminal. At a minimum, attach to a solid
metal body or chassis part that provides an eective ground path as long as the light system is to
be used.
• To be an eective warning device, this product produces bright light that can be hazardous to your
eyesight when viewed at close range. Do not stare directly into this lighting product at close range
or permanent damage to your eyesight may occur.
• Frequently inspect the light system to ensure that it is operating properly and that it is securely
attached to the vehicle.
• Refer to the instruction sheets included with related products for additional precautions and
information.
• File these instructions in a safe place and refer to them when maintaining or reinstalling the
product.
Failure to follow all safety precautions and instructions may result in property damage, serious injury,
or death.
Product Overview
The Legend/LPX light bar family uses three ROC Big Board panel assemblies. End and Intermediate
panels are two per bar, all lengths; center panels are one for 53-inch bars, two for 61-inch bars, and
three for 70-inch bars. These panels, supplied with LED Options installed, are available from the
factory on a custom order basis.

Installation
DISCONNECT POWER: Disconnect ALL power to the light bar before any maintenance is
performed. Failure to do so may result in property damage, serious injury, or death to you or
others.
COOL BEFORE HANDLING: After prolonged operation, the unit gets hot and can cause burns.
Do not touch the unit while or shortly after it has been operating. Always allow the unit to cool
before handling.
Removing and Inspecting the Dome
PROPERLY TIGHTEN NUTS: To prevent damage to the light bar, do not overtighten nuts.
To remove the dome:
1. Remove the barrel nuts, and then carefully remove the dome to avoid damaging the lip seal.
2. Verify that an O-ring is under the head of each barrel nut and not stuck to the dome. Use a wooden
or plastic pick to remove the O-ring from the dome to prevent tearing the O-ring.
3. Inspect lip seal (on base) and O-rings to ensure that they are not torn, brittle, or damaged. Replace if
necessary. See “Ordering Replacement Parts” on page 4.
4. Back the barrel nut counterclockwise until you hear an audible click of the threads engaging, and
then tighten normally to prevent cross-threading on reassembly.
