Intelight ESB interior (yellow section) LED array lit 70% of the LEDs, 30% programmed to be off. The power supply circuit board on the left. The circuit board on the right serves three purposes: One, holds the WI-FI modem to communicate with a laptop or PDA/Smartphone to program the signal. Two, it holds the photocell to dim/brighten the signal based on outside conditions. Three, it has built in diagnostics that record LED activity and monitor it for failures. That information can then be sent to the laptop for reporting information. Definitely the most high tech signal head made. Keywords: Traffic_Lights

What do you do when an individual LED burns out, replace the entire LED board or are you able to replace only the bad one? We have 3M and McCain PVs that use LED plug ins that are retrofit for the incandescent, and just replace the entire unit.

the 3M and McCain PV LED retrofits are not very reliable. They were quick designs to put on the market to keep those old optically programmable heads in service. The LED plug ins (especially the ones made by GE) have very high fail rates. Plus you need to disable the photocell in these. These in the Intelight have very low fail rates. Its the first American traffic signal 100% designed for LEDs only. If an individual LED does fail, it won't affect the rest of the array
