Headlight Upgrade To H4 A Couple Questions

I’m going to install a fresh, upgraded (w relay) headlight wiring harness and H4 E headlights. I’ve read a number of articles. Most makes sense; actually it looks fairly simple. Still, a couple questions:

1) Harness: I’m looking at the Daniel Stern RIK-2 harness kit (where you provide the wire and assemble it yourself ($49-),


the RJM pre-assembled harness ($69-) http://www.rjminjectiontech.com/prod...dlight-harness

Assembling the kit doesn’t seem too difficult (I can crimp and do crude soldering), but the preassembled kit would be nice (I’ll pay the extra $20- for a plug & play kit). My question is whether there are issues with the RJM kit “fit”. Has anyone installed it and found the need to lengthen or shorten the wires (if I assemble the Daniel Stern kit, I can make it the exact length that fits for me).

2) Any recommendations for bulbs that provide both improved output and reliability? I’ve read a number of posts where people are burning out H4 bulbs every 3 - 6 months. That could be inconvenient (even if I carry spares).
Edit - I also read one post where off-road vibration was the cause of bulb failure. Given this vehicle and the trails I take, off-road vibration is to be expected - I need a fairly reliable bulb.

3) I haven’t decided if I’m going with the $35/ea Hella housings or the $80/ea Ciebe. I’ve read the Ceibe’s are “best” (all that Daniel Stern sells). But I’ve also read posts where people are very happy with the improvement with the Hella’s. Has anyone used both under similar environments & bulbs and can say if the difference is significant?

For what it's worth, I upgraded my headlight wiring with this- http://www.ebay.com/itm/370658138040 . This complete wiring kit has ceramic ends so heat won't melt them. I have Rampage aluminum and glass lights (http://www.quadratec.com/products/97009_500_07.htm) and a pair of Osram bulbs. I don't run much at night but when I need the headlights, there is a noticeable difference in light output after the upgrade.
