Back to original question, what comes out of the receiver? Simple answer, it's whatever you put in
Your BEC circuit on the ESC supplies power to the system. Whatever you have the ESC set at is what you will see at the receiver output.
Receivers can tolerate a wide range of input voltage, while the critical part is your servo, typically the ESC is set to 6V or 7.4V but read your manual.
You can buy plenty of 5V LED, they will give you an operating range on voltage. !2V might work, they will be very dim and probably useless, again depends on manufacturer. LEDs are typically in operating range at spec voltage +/- 10% i.e. 5V is 4.5-5.5V and once outside those tolerances it depends on what the manufacturer used in production and hard to predict. Most likely, only the color will change a little.
You can buy bunches of these, they work from 5-12V and is what you will need.

Wow, thanks for the lesson! Seriously, this is just one of those things I never learned much about but it's a lot of fun to mess with.It's a 12v strip with all 3 LEDs per segment in series with a 240-ohm resistor in between the 2nd and 3rd led per segment. This means each led is probably rated at 4v and the resistor is just there to limit current.
Edit: I decided to take a screen shot and draw on it showing how I percieve the circuit traces running and how the strip is rated at 12V.

To give a small electronics 105 lesson.
LED's are "current" devices, same as diodes since they have diode in the name. Diodes a forward voltage, think of it like a wall, once the voltage applied to the diode gets to that "wall limit" or above near 100% of that current will passthrough the diode. Standard 3mm and 5mm LED's run anywhere between 1.8v per LED and 3v per LED for fancy colors like white, blue, pink, uv, etc.
When find bigger ones like these or the ones in say a 120v flood light especially those huge square ones rated at 120v, are just a large physical body with a certain number of little LED dies placed in series and parralllel to achieve 120v or what ever voltage.
Hence why in this LED strip you have 3 per segment, 12/3 = 4v per LED "cube".
I was actually wondering about the resulting drain on the battery, thanks for the explanation!I bet you're wondering how all this relates to you, well let's say you could use these strips and you ran them around the inside of your car's body, you used a total of 5 segments. At 50ma per segment and using 5 segments the LEDs would be drawing 250ma constantly from your ESC and battery while in use. To put that into perspective, if you were using a 2500mah pack 10% of its usable charge would be used up by the LEDs alone.
