The Hella's were wired up through a Piranha loom, much better light output. And fianlly, I added a pair of Lightforce 240's, with high output bulbs, on a Piranha Loom, matched with 3x Hella 181 with 130w globes on a Piranha Loom also. I also upgraded the H4 bulbs to Philips 80 , which are rated at 80/130w. These are also on a upgraded loom. The light output is amazing and makes night driving so much easier.
