If the ARB lights aren't working all the time, then you've got some bad connections.
Since the wiring needs to be redone anyway, what I'd personally do is one of two options.
1) Tear out all the wiring you put in for your ARB blinkers. Get the ARB harness (triple setup) and have the ARB light, front marker lights, and corner turn light all as dual function.
2) Tear out all the wiring you put in for your ARB blinkers. Get the dual harness and run the marker and turns as dual function lights. Install clear lenses and uber bright LED's into the housing (or better yet, fab in some driving lights). Wire it up as a separate driving/camp light.
I personally would lean towards option 2. You don't really need the ARB lights to be markers/blinkers, and some DRL's would be uber nice there to supplement the light output of the low beams at night......
Thanks for the explanation

Yeah, my ARB lights are wonky...It is actually the cheap ARB housing and internals vs. the wiring, causing the bulbs to lose contact. I just get tired of farting with them every month.
Based on this, can I change my order to 1 of each? (assuming the ARB version comes in at the lower end of the increase range)
I'll throw the ARB version into my LX and when/if I ever retrofit the ARB lights to be something other than just markers I can tie off the extra wiring. I'll throw the regular version in the 80 stocker and upgrade it at the same time.
