Here is a vendor website for tower lighting systems.
Basically, (in the US) if your tower is over 200’ (AGL) or near any airport local flight path (need to check with the FAA) a communications tower must have either:
1 red light system for night time visibility and be painted alternating aviation orange and white for daytime visibility
-or-
2 red light system for night time visibility and have a high intensity white strobe system for daytime visibility
-or-
3 Have a dual mode (dual intensity) white strobe system for day/night visibility
There are several rules regarding what lighting system can be installed and where, and the numbers & types of lights depending on tower height and vicinity to an airport or community.
Also, all tower lighting systems must be approved through the FCC & FAA (in the US) prior to installation.
If you are unsure on whether or not you need a system or what type of system is right for your situation, a qualified tower contractor can guide you in the right direction. To find a qualified tower contractor in your area (again in the US) you can contact the National Association of Tower Erectors (NATE) at
Hope this helps...
