Does the Nikon D5100 have a 'Bulb' mode?
I've been tryng to find if the d5100 has a 'Bulb' mode. And if it does, how do you activate it?
Yes it does
have you read your manual? If not, that would be a good place to start
it is the same for pretty much every DSLR ever created
Did you keep your Owners Manual? If so than Why haven't picked up and Started Reading your Owners Manual Yet? Because this type of information is actually in the Owners Manual.
Rule # 1 - Read the Owners Manual
Rule # 2 - Read the Owners Manual
Rule # 3 - Read the Owners Manual
Otherwise Try Reading the Owners Manual to find this type of information
Here's a little hint.

Look at Page 66
Just turn the Mode dial to S (Shutter priority) or M (Manual) and adjust the shutter speed with the thumb wheel until it reads B or Bulb.
