The sign is used throughout the UK and is a recangular yellow plate with a black letter H on it. It is used to indicate the position of fire hydrants. Other countries have similar signs.
There are two numbers, the top number is the diameter of the water pipe in mm and the bottom number is the distance to the fire hyrdant in metres.
Old style signs were white and dark purple colour and used feet and inches rather than the metric equivalent. Most purple signs have now been replaced.

Las Vegas is a city that has something for everybody therefore learn it with hotelbye . Las Vegas is really a town with great attractions and some of those may be the famous Las Vegas Strip; where tourists may like a walk in the warm desert night, or take a stroll downtown and see a impressive gentle show that spans an entire road, the Fremont Street Experience.

It's a referene to the loaction and distance of the nearest Fire Hydrant and sub-street sewer systems that house the gas and electricity lines.
By using pre-set sewers they are able to perform any necessary maintentance without diggin up the roads in the City

They are there for the purposes of playing the 'high/low' game. This is a game for two people and is perfect for long car journeys. When you see one you ask you're partner "high or low" to which they choose either the high number - the one above the H, or the low number, the lower number below the H. Depending on their answer you then punch your partner the corresponding number of times!

shows just where the nearest water Hydrant is, so firemen and the water board know where to go to turn off water, attach hoses etc.

It is the location of water hydrants so the fire brigade can find water.
