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

Are you:

Colorado?

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.

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.

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

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:

1) Indeed! 2) Mostly

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.

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.
