2007 Iveco Stralis Error Codes

I just disconnected the trailer wire, it doesnt have a trailer at the moment and the front frame computer error went away.
Anyone know what wattage globes should be in the front indicators? Im assuming thats the problem as they are all definitely working.
In Australia they wont pass fast flashing indicators for a road worthy certificate so i need to get it fixed before i can get it on the road.
Cheers,
Nick
