Makes sense if you think about it - they are a lot more visible, and if you consider the fact that the new 95' Towers have not even gone out for bid yet, and the amount of issues and delays with the current order of 75' Towers, the 2001 and 2002 95' Towers are going to be around for a LONG time!!! I know Ladder 170 also has LED lights now, but I think they were part of the experiment testing different LED systems back in 2002 or so. I've also seen quite a few rigs with the red halogen lights above the headlights switched out with LEDs.
