Wiring Off Road Lights

[MaineH3]

Hey everybody, I hope someone on here can give me some advise. I recently bought (4) Hella FF75 lights. The main reason I bought these are because of their low profile; they are going on a custom lightbar I am having made.

So, here are my questions. What gauge wire should I run off my battery to power these and what size fuse directly after the battery? I plan on splitting the wire and running to (2) relays to power the (2) sets of lights; they each are rated at 55 Watts.

The Hellas came with the relays, switches, connectors and wires. Unfortunately they did not label the wire so I have no idea as to what gauge it is. I am assuming it is 16 gauge, is that correct?

Any help is greatly appreciated.
Thanks,
Luke
