How does the button on the pedestrian crossing lights work? Does it actually send some sort of signal to the traffic lights, or is it just a psychological thing? It seems rather random timing-wise.

I'm trying to find those pictures that light up to make them look more hi-def, and I can't seem to find anything because I don't know what they're called or what to search for. They look like hdtvs kind of, except with a picture. Some of them have flowing water, well it looks like it's flowing because of the lights, and that's about as good as I can describe them. I've seen them in stores and I've been interested in getting one, but I wanted to look at some online first. Thanks for your help.

We are designing a semi-modern, semi-classic kitchen remodel in our 1922 Craftsman / Mission Revival bungalow. I am very much opposed to using cans in the ceiling for light, although I realize I may be in the wrong; my wife insists that they are necessary, even though there is a bright multi-light unit from Rejuvenation Hardware over the dining nook and various period-accurate pendants for spot lights on the counters and some under-cabinet over-counter lighting.

I have two light fixtures in the entryway of my house, near the dining room. There are three light switches in the immediate vicinity that will turn both fixtures on or off.

Fluorescent light problem:

I have a fluorescent light fixture in my bathroom using two, different-sized, doughnut-shaped bulbs. Lately it's been taking a long time to turn on (15-30 minutes) after I throw the switch in the morning. If the fixture has been running for a while, this warm-up time seems to go down. Does this sound like a ballast problem (and thus my landlord's problem), or a light-bulb problem (mine)? I'm leaning to ballast because the lights look fine once they start, but I haven't been able to find the same symptoms on the half dozen fluorescent lighting websites I've looked at so far.
