The beeping was nonsense measure from the start, once you have more than one piece of equipment with it, or moving more often than once a day and when you can not immediately stop what you are doing and looking for it, it gets completely nonfunctional (just because you can not locate the beeping source by hearing only), it just remain super annoying and so caused loss of focus of all people around (so making the safety level actually worse on the site).
Shameful is, this limitation had to be known from the getgo (effects of similar sounds were studied way before WW2), yet still regulators pushed it through as a claimed "safety measure". It just allowed the "We did our part, we can not be responsible for people not paying attention" excuses...

Very interesting information!, I’ve always associated white noise with a sound that can cancel other sounds?, which makes total sense for a reverse alarm.

Neon lighting is still very popular around here. I haven't yet seen an LED neon replacement in an outdoor application. As for HPS, it's still seen sometimes in rural areas and parts of Hillsboro, but most of it has been replaced with LED. Many parking lots still use MH and sometimes HPS, though.

 It's not just British names that we Americans can't pronounce !! I've lived all over the US and heard all sorts of names of cities , towns , people , etc. here that get massacred by unknowing people !!

 The new "seagull" reverse alarms are referred as "white noise" alarms . They're supposed to be more easily identified than the old "BEEP , BEEP , BEEP" which some people tend to just drown out and ignore . I found a video of the talking version on YouTube...I'd be looking for a hammer !!!!

 @ MedVed : I actually agree with you about both the rear fog lights and the DRLs . I've found them a bit blinding on some cars depending on where the factory installed them . Some cars have them low in the bumper while some have them in with the taillight cluster. The low ones aren't near as bad . As for the DRLs , it couldn't cost much extra to install a light sensor with some form of warning light in the dash or just make automatic lamps standard equipment ! My 2003 Mercury has automatic lights which also turn on whenever you activate the wipers . Lights on when the wipers are on is actually a law in some states here .

I blurted out 'Slob han'

My SDW-T driver arrived! SDW-Ts give a really nice kind of light, and it's also highly unusual to see it coming out of a sodium lamp.
It does make me wish i had a bunch of the very lowest power ones, so i could use them indoors. The 100w one is very bright - though not very efficient at 48lm/w.

I’m pretty sure there is a US version of Siobhan?, which is pronounced as you probably say it?  , but the Irish version doesn’t say the Shiv part.

Hey Rich, I mis-pronounced your eldest daughter

Today, while shopping for lights, the shopkeeper was amazed how well versed I was I lighting. Even the officials of brands like philips and osram couldn't give as much information about the lamps as I could. I was even invited to a meeting about lighting !
Lesson of the day- you will find the right person with patience.
