Me again,

The lights on our new family member (Mk3 8v GTi) are pretty poor. I've been reading about upgrading them (but still don't know enough) and wot-not with Dizzy's loom, but AFAIK it's not available for the Mk3 yet.
What is the brightest option i can go for, without melting everything?? Is it 80/120 or something, i seem to remember reading on here.
I've seen these Xenon lights on eBay, anyone rate them?
I've gotta do something to see better in the dark and i'm out in the sticks so i wanna see where i'm going...
Cheers,
