i guess they want these to be real visable,these rural intersections might be dangerous at night because sometimes they're in really wooded areas and the side road turning onto the main road might not see traffic coming at night.
Well the good thing is if one light stops working, you go the rest........2 stops working you got 2 left, 3 stops working you got 1 working...finally all 4 breaks....LAWSUIT!
When I don't wear my glasses ( which is usually always exept in school) the individual diodes are hard to identify. They look almost blended together. When I'm wearing my glasses, those flickering and dead diodes really bug me.
Yeah. The lensed LEDs hide the bad diodes better, but at the same time affect brightness by the work crew not being able to detect a faulty device until it goes completly out. Also, those lensed LEDs have a very limited beam spread. On a windy day, the signal heads will rock back-and-fourth and the light will fade in and out, almost like a flashign light, but the fade in and fade out are slower and not a constant beat.
we do use Incandescent-Look Modules in all our New Signals...the fade would be much less pronounced on Fixed-Mast setups than Spanwire setups which allow the signals a higher degree of motion in windy conditions.
why do we still call them "Pixles"? they're not pixels they're LED Diodes.
