LED in parallel

[Dr Syn]

Hi all. If a particular single LED needs a resistor before it , what would you need if, say, you had six LED's in parallel. Could you get away with just the one resistor at the start of the positive, or would you need one at every LED.
Cheers

That might depend on several things. One on positive would work for all if they all were the same and they give same brightness, if you want them to have different amount of light, you need separate resistors.

Thanks Kurt, they are all the same so that's great. On the bit I'm doing I don't actually need resistors for these particular LED's but it's nice to know if I need to dim them.
