Indicators turn headlights off...

Probably an earth issue!

check all earth wires from headlights and indicators!

THE CADDY FRONT HEADLIGHTS SUFFER FROM BAD CONTACT AT THE INDICATORS.THE CONTACTS AT THE HEADLIGHTS SIDE DO NOT MAKE GOOD CONTACT AND AS A RESULT BCM DOES NOT SEND VOLTAGE.THE CHEAPEST WAY TO REPAIR IT IS TO MAKE A SMALL MODIFICATION AT THE HEADLIGHTS.CUT THE TWO BLACK CABLES GOING AT THE CONNECTOR INSIDE THE HEADLIGHT WHERE THE SOCKET OF THE LIGHT BULB SITS.DRILL 2 HOLES AT THE SOCKET AND DIRECT THE TWO CABLES U CUT THROUGH THE SOCKET AT THE EXACT POINT OF THE CONTACTS AT THE SOCKET.SOLDER THE WIRES AND U ARE GOOD TO GO.

Multifunction switch or a ground issue.

I have had this happen before - this is the multifunction switch on the steering column. The one on my Ford took about 10 minutes to change (two bolts). My problem - I would turn my lights off, then turn them back on and nothing, then they would suddenly pop on. after a bit my lights would not come on at all. I had to drive with my Flash to Pass lights for a couple of days when driving at night.

I hope this helps!

We do no have this make in the USA so have no info on it. Sorry

Is this an optical issusion and the indicators are merely being "flooded " by the wash of light from the headlights. Try a stronger bulb in the indicators or use amber bulbs if not already fitted.

Hazards are a separate circuit.
Check fuse for indicators, suspect stalk switch - or control relays for the indicators.

FIRST, IT IS V E R Y DANGEROUS, THE SIGNAL SWITCH NEEDS TO BE REPLACE,IF NOT IT WILL SHOW THAT YOU ARE READY TO TURN, AND YOUR NOT TURNING

I had the same problem. Horn not working and indicators not self cancelling.
After removing the steering wheel I found that the central two pronged collet, that engages with the steering wheel and drives the horn contact slipring and indicator cancellation, had worn down its prongs. this had caused the horn wires to stop rotating and they had been snapped by the motion of the steering wheel.
the ideal solution would be to replace the collet and horn wires but I managed to repair both

check the headlight relays under the hood also fuses under the hood and in the interior fuse pannel.
