Similar, yes.
Firstly I presume that you've done the most obvious thing, which is to check the fuse (J/C 5, Fuse 15) which is shown on the circuit diagram I uploaded, and that you've checked the circuit diagram for the indicators and noticed that it is the same fuse.
Surely no-one would waste the time of people on a forum without doing the basics first. So, using a little logic and some knowledge of the system....
Both the headlights switching and the indicator switching are controlled by a computer. The only place where those two, completely separate, circuits come together downstream is in the stalk. So, logic says that the stalk is the first place where one should look for the problem.
The other option is to look for complete breaks in the cabling between the steering column and the ETACS-ECU. Based on what you've told us, which includes no mention of any damage, it is only reasonable to look at the first possibility, first.
Now, considering the stalk itself. The headlights switch in the stalk is known to give occasional problems. The identical stalk is used in the Pajero and it was the cause of a recall because of dry joints in the connector where the stalk itself plugs in to the indicator switch on the steering column. So, it's feasible that a Triton, some 12 years old, could be suffering from the same issue. Solution in this case is to remove stalk, clean the contacts and replace with a smear of electrical grease on the contacts. This may solve the problem, but, if not, then stalk replacement is the answer since logic then tells us that the problem is in the switch at the end of the stalk, which is not serviceable.

If work is so terrific, why do they have to pay us to do it?
