If you look near the relays you will see a circuit breaker. It looks like a square metal block with 2 large wires going to it. This will be corroded internally and failing.

Agreed.  Or a bad earth.

I also agree with this. Had it happen to me before.

 

This is the part in question - metal box next to relay

if you've had the dash out, check the earths behind the kick panels also, one used to go on the dash bracket, but i ended up screwing it separately with a tek screw because i was having issues.
 

check what the others have said also. the one Mr Polson suggested runs the power for the whole car, if it's tripping out you'd lose nearly everything

I must check this out on mine as I loose power when I flash the high beam when my lights are on. Luckily I don't do much night driving.

ketspano, which circuit breaker do you refer to, (under the dash) next to the blinker can ?

that one sounds more like an earth.. if the one going from engine to body is off(near the left middle bell housing bolt to firewall after you forgot to undo it on engine removal.. 4 times )
could also be the earths near the headlights

the circuit breaker under the hood near the battery (same as the photo Mr Polson sent)

After having a new dash installed in my XF, I found i only had PARK LIGHTS no HORN, and the Indicators worked some time. Went  to the AUTO ELEC and he told me I needed a new/another indicator/ wiper assembly.. Fitted and works great now....$30 for the part, $ 95 to fit...
