I think the stock wattage is something like 55/65 watts for low/high - not sure how high you want to push it on the stock wiring - don't want to melt wires or have a fire.
I had considered doing something like 55W/100W or 65W/100W. BUT, if your connectors are that bad, it might not be a bad idea to put a voltmeter on the leads with the lights on and see what kind of voltage your getting to the bulbs and compare that to your voltage at your battery - just a couple volt drop has a big effect on the perceived brightness of the bulb, you might consider rewiring, or at least wire in a couple of relays and feed power straight from the battery - use the old wires to control the relays - somewhere I've seen schematics for it. In fact, ARB I think sells a plug-n-play kit for relays, I think its like $90 or so though - might be money well spent - I'm not sure if RRC's use a relay or just feed power through the headlamp switch, but higher wattage bulbs could burn it out and those are like $60 or so to replace.
I think I'll do the relay trick at some point and then go to something like 65/100W.
*Edit - IPF has a plug n play harness for ~$80 and then I found this one for ~$36, but its on backorder.....LOL
