Hold on, are the relays 12v or 5v - earlier in the thread you put 12v relay, but the above seems like its 5v?
Think i'm going to give this a pass sadly, too many components with voltage changes and things I simply don't understand! - thankyou for the effort though, the more I read the more confused I get so probably not a great iea for me to be messing with my only light!
Doesn't help that im in the UK and most components you linked aren't readily available e.g the relay is this one - without a "high / low" - whatever that means, that your link has

Edit: Its also going to cost £60 ($78) (and I already have the pi)
I cant understand why if the Pi has PWM control, I cant just splice into the PWM wire/s on the light and use the pi to control that (and keep everything else inside my light unit)
