• Was the change from "I'm" to "it's" intentional or not? – rschwieb Jan 16 at 20:19
• @rschwieb it was definitely deliberate. Yes. – Outman Jan 17 at 7:26

Are you

a flag ?

I'm famously rectangular

flags are famous (country or other localities flags) and rectangluar (except a few, e.g. Nepal)

Sometimes it's dark

e.g. pirate flag

Sometimes it's not

e.g. white flag

If you use me while I'm wet, you might get killed!

WETFLAG is an acronym for steps to take for first aid for children in medical emergency, see e.g. here : Weight Electricity Tube Fluid Lorazepam Adrenaline Glucose

• Wow, that last spoiler is an interesting take... – rschwieb Jan 16 at 20:45
• Gets an awesome-if-true vote for the last spoiler. I don't think it's the answer, but it deserves an upvote anyway. – Ben Barden Jan 16 at 20:58

• @Flying_whale I know, but as a swiss person, I just wanted to point out how special we are :P . I mean we even convinced the United Nations that our Flag should be square in front of the UN building in Geneva. P.S is your name a reference to Gojiras song "Flying Whale"? – MindSwipe Jan 21 at 12:22

Are you a

Toaster?

I'm famously rectangular

Most toasters are basically rectangular, as is most toast

Sometimes it's dark Sometimes it's not

Bread can be toasted a lot or a little

If you use me while I'm wet You might get killed!

A toaster in the bathtub can be a shocking experience

• At that rate, why a "toaster" especially? One would think that simply power outlet units are more consistently rectangular than toasters... – rschwieb Jan 16 at 20:22
• @Outman When you respond to the answer and state the answer itself, it kinda defeats the purpose of the spoiler formatting. – JeffC Jan 16 at 21:48
• @rschwieb It's a trope by now. I don't know if Groundhog Day was the first, but it's one of the most famous. – curiousdannii Jan 17 at 6:54

Lightswitch?

It's also known as a pocket square

Sometimes it's dark

Different colors or designs, or perhaps blood

Sometimes it's not

Lighter colors, OR could be a wordplay— "sometimes it's snot"

If you use me while I'm wet You might get killed!

Wet meaning already used by someone else. Especially in older times, such poor hygiene would spread disease and death.

Are you:

Spongebob Squarepants?

He is a famous rectangle. All squares are rectangles.

Sometimes it's dark

Spongebob can have a dark sense of humor sometimes.

Sometimes it's not

The show can also be really lighthearted at times.

It's a kids show

But if you use me while I'm wet,

You might get killed!

If you pour water on your TV, you might get electrocuted

• That fits the pants! – Coconut Jan 19 at 4:43

Are you:

I'm famously rectangular.

Colorado the state is about as close to rectangular as a piece of the Earth's surface can get, and appears rectangular in several map projections.

Sometimes it's dark / Sometimes it's not.

COLOR ado? Or maybe, referring to appearance of the river in various places or at various times?

If you use me while I'm wet / You might get killed.

In many parts of the Colorado River nowadays, if there's more than a trickle then it's likely because of flash flooding.

Are you a

light switch

I'm famously rectangular

most are

Sometimes it's dark

when its off

Sometimes it's not

when its on

If you use me while I'm wet You might get killed!

Well, some people think that

Are you a

Display screen

I'm famously rectangular

Screens are nearly always rectangular, to the extent that the phrase "square eyes" is used to derogatorily refer to someone who spends too much time looking at one.

Sometimes it's dark

Screens are black when off.

Sometimes it's not

They're bright with light when they're in use.

If you use me while I'm wet
You might get killed

Like any electrical equipment, screens are typically dangerous when exposed to water.

I don't know that I really like this answer but are you a

I'm famously rectangular

Roads are long rectangles (until they bend)

Sometimes it's dark
Sometimes it's not

Outside when you are driving

If you use me while I'm wet
You might get killed!

I was thinking of the slippery when wet signs you see on roads, at least in the US

Are you:

a mobile phone?

Rectangular in shape, mostly black or dark colors, and can kill if used when wet!

• I can't see any way that a [answer here] could kill if wet. Maybe if you shorted the battery and that causes a fire. – hat Jan 19 at 7:58

You're

Wall Socket

Famously Rectangular

Wall Socket are Rectagular

Sometimes it's dark Sometimes it's not

Some Wall Socket have light on them. Also it can be reference that you can plug a light into it.

I'm penetrable and deep

You can plug into wall socket.

I'm a joy for the kids

Kids like put their fingers into wall sockets.

But if you use me while I'm wet, You might get killed!

• From all the answers I've seen, this one comes the closest to matching all hints. But "a joy for the kids" is still a bit of a stretch, I think OP intended a different solution. – Fabian Röling Jan 20 at 19:51

I'm thinking you're:

I'm famously rectangular

Indeed. Almost every card driver knows it.

While not all are in a rectangular shape but some are:

Sometimes it's dark

Sometimes it's not

Depending on how your cruise control paint color. And the brightness inside your car.

If you use me while I'm wet

You might get killed!

If you use it on rain, well you risk of accident as stated here. Everyone know you risk your life when having an accident.

Are you

an electrical circuit with a light bulb and a switch?

I'm famously rectangular


Circuits drawn on paper or digital images (used for example in learning books) almost always have a rectangular shape.

Sometimes it's dark
Sometimes it's not


When the switch is off, a light bulb does not receive energy and is also off, so "it's dark" (this explains why there is "it's dark", not "I'm dark")

If you use me while I'm wet
You might get killed!


Of course, this is about a risk of electric shock.

Are you a

Zebra crossing

I'm famously rectangular

The Beatles walked across one in Abbey Road and the lines are rectangular

Sometimes it's dark

The black lines

Sometimes it's not

The white lines

If you use me while I'm wet You might get killed!

They can become slippery while wet and if you fall you might get hit by a car

Summed up in this image:

I think you are

A phone

I am famously rectangular

Non rectangular phones are rare

Sometimes it's dark

The screen when the phone is turned off

Sometime it's not

The screen when the phone is turned on

If you use me while I'm wet, you might get killed

A phone contains electricity, so it can be dangerous

• I'd like to see anyone dying from 5V or 3.3V DC! In fact, such low voltage can't even be felt. – hat Jan 19 at 7:56

Here I go~

You are a

Dance floor!

I am famously rectangular

Dance floors are pretty rectangular, especially those with checkered light patterns you see in disco clubs.

Sometimes it's dark Sometime it's not

Places with a dance floor usually have lights flickering on and off.

If you use me while I'm wet, you might get killed

Slipping on a wet dance floor while dancing might get yourself killed.

You are a

trampoline

I'm famously rectangular

There are many rectangular trampolines.

Sometimes it's dark

It is black material.

Sometimes it's not

It could be another color though.

I'm penetrable and deep

They get deep when you jump down on them.

I'm a joy for the kids

Trampolines are fun.

But if you use me while I'm wet, You might get killed!

It is dangerous to jump on a wet trampoline.

Sandbox

1. Rectangular

2. Fun for the kids

3. If wet turns to quick sand

• Welcome to Puzzling.SE! In the future, please hide you answer using the ">!" spoiler notation. – Brandon_J Jan 18 at 16:48

I really don't think this is the answer you're looking for, but I'm going to post it anyway.

You may be a

Roller Coaster

I'm famously rectangular

Roller Coaster cars are typically rectangular. This could also apply to multiple cars hooked together.

Sometimes it's dark

Some roller coasters have tunnels.

Sometimes it's not

Some roller coasters are out in broad daylight.

I'm penetrable and deep

The tracks can be "penetrated" through the holes between the rails. The tracks drop from a high point down into a deep valley.

I'm a joy for the kids

Lots of youth love roller coasters!

But if you use me while I'm wet, You might get killed!

Heavy rain might cause some dangerous conditions for roller coasters. Also, when raining, there's potential for lighting strikes.

And per the tip in your comment, "There is climbing involved!"

Roller coasters climb up to the tops of some of the peaks.

Well a few people have guessed something similar to this, but not this exact object.

Are you

A tubelight ?

I'm famously rectangular


Tubelights are rectangular

Sometimes it's dark
Sometimes it's not


Tubleights are notorious for flickering when initially started (thus sometimes its dark sometimes its not) [though could just be a reference to the fact they are a light with a switch]

If you use me while I'm wet
You might get killed!


Using any electrical appliance when wet is just a bad idea

Not sure you are allowed to give two answers, but here are two:

You might be a

1) TV 2) Swimming pool

I'm famously rectangular

1) Indeed! 2) Mostly

Sometimes it's dark Sometimes it's not

1) Off/on 2) night/day

If you use me while I'm wet You might get killed!

1) As any other electric devices (e.g. toasters), if they get wet and you plug them in, you might die of electrocution. 2) If I'm full up, you might drown!

Too many similar answers. Here comes a weird one. Are you

A pool for spent nuclear fuel near let's say a nuclear reactor

I'm famously rectangular

Most pools are rectangular.

Sometimes it's dark

Nearby nuclear reactor not running, all lights out. Note it doesn't say I'm dark but it's dark.

Sometimes it's not

Reactor running, all lights on at least for security

If you use me while I'm wet

The pool only needs to be full of water when in use

You might get killed!

As so nicely stated in the last paragraph in this what if you'd die quite fast trying to swim in a pool for spent nuclear fuel while in use.

• A joy for the kids ? haha – Joe Derksen Jan 18 at 18:25
• This was the closest to the answer I wanted. And I believe it's my fault for being too broad that you thought of a nuclear pool instead of a normal pool. – Outman Jan 21 at 7:29
• @Outman normal pools are booooring :P – findusl Jan 21 at 7:38
• @Joe Derksen the question was edited later. Maybe the kids enjoy it while on an excursion? BTW my school was called Derksen ;) – findusl Jan 21 at 7:40

Here is my guess

Floor tile
Rectangular, all colors design, and slippery when wet

OR

Stairs
Since climbing involved

I actually have two guesses. First:

Parachute

I'm famously rectangular

Many parachutes are rectangular, particularly the steerable ones.

Sometimes it's dark

Sometimes it's not

Parachutes come in many colors

If you use me while I'm wet

You might get killed!

A wet parachute may not open properly and may be too heavy, causing you to fall to your death.

And second:

Blanket

I'm famously rectangular

Blankets are almost always rectangular

Sometimes it's dark

Sometimes it's not

Likewise, blankets come in many colors, but you've also got the point that they are generally used at night when it's dark, but also can be used in the daytime.

If you use me while I'm wet

You might get killed!

A wet blanket can cause you to die of hypothermia.

Okay, I think now is the right time to answer my own question.

I am a

Swimming pool.

I'm famously rectangular

Most swimming pools appear rectangular.

Sometimes it's dark / Sometimes it's not

This is mostly referring to day and night but also to swimming pools having lights.

I'm penetrable and deep

You can penetrate a swimming pool by jumping into the water (diving) and they tend to be deep.

I'm a joy for the kids

Children are fond of swimming in the pool in a hot summer day.

But if you use me while I'm wet, you might get killed!

You can die of drowning in a water filled pool if you can't swim.

• This was my first guess but I gave up when I see the other answers. Have never thought that this turned out to be the correct answer Sad :( – Omega Krypton Jan 20 at 23:34
• @OmegaKrypton: I also thought about a swimming pool, but thought the answer would have to be different. – hat Jan 21 at 10:00
• I also suspected the "dangerous when wet" was camouflaging this, but they're as likely to be circular or curvy, so it seemed like a weak candidate. "Penetrable and deep" also does not really put the nail the coffin for the "solution" either. Nice try, but keep refining your puzzle-writing skill :) . ( I have to confess, my level is not even this high :P) – rschwieb Jan 21 at 14:40
• @rschwieb thanks! It was fun while it lasted - I am no puzzle guy but I just wanted to contribute something to the community :) – Outman Jan 21 at 14:55
• This was my original guess as well, but I felt that "Sometimes it's dark / Sometimes it's not" is too much of a stretch for a swimming pool. I suspect that probably threw a lot of people off, considering that there were 26 answers and no one got it. – TACHEON Jan 21 at 15:41
