No prob - here are the basic instructions:

It's actually easier on the L300, once you get the headlights out. I used the oven technique, but I found that there was only a simple gasket, and no goop holding it all together. Having said that, I do think that heating it up in the oven did really help loosen everything up. But basically, you just pop the clips off, and then pry the whole thing apart - use common sense though, you don't want to damage the lenses.
Once it's apart, you peel and stick the LED strips however you like. I used the side illuminated style. I drilled a small hole in the back of the light assembly, fed the wire though, and sealed it up with a little silicone. Put the whole thing back together, feed the wires into the cab, put the lights back in. If you want them to turn off when the headlights are on - see Jay and Christine's post above (show offs!). I used the circuit from the DRL module for power, but I think you can use almost any circuit that comes on with with the ignition (but not the accessory position.) You can buy the light strips from walmart for $40(ish), or you can order them online for $4 from china including shipping but you have to wait 6 weeks (link a few posts earlier).
The hardest part is getting the headlights out. You can search here to see how to do it.
That's about it. Hope this makes sense, I'm drunk posting.

Good Ship
