I have the same problem. I don't have a soldering iron. Even if I did, I still wouldn't be able to do it. I just can't solder.
I wonder if you might be able to somehow use those LED light strips like they sell at Pepboys? I think they're designed to stick on the outside of your car to make it LOOK like you have LED DRLs or something. But if you wired them into the internal wiring somewhere (like the aux wire -yea, they'd be on when the ignition was on, but it seems easier than trying to replace them).
I hope to try it one day. IDK, maybe you'll have better luck soldering.
