I have installed a few of these units, all in the name of energy conservation. I changed all colors. Walk/don't walk couldn't be changed due to size.

I will get the specifi information Tuesday when I get back into my office.

One thing I have noticed. These units give off great light, but sometime the green makes it hard to see ahead of your vehicle.

PS. I only have two intersections that I have to maintain, other than these, there are 3 other sets, maintained by the State of Colorado highway dept., and these have been either changed (2 sets) or installed new (1 set) to use the new led type lamps.

I have a friend in Alamosa, Co. that won the state of Colorado contract to change all units in the state. Took about 3 months, in 1999.
