When do they flash, ie starting driving, over bumps?

If all the lights are flashing I would be looking at the ignition switch as it switches ALL to ON at startup to check they all work. If it is contacting then not, the check system will go into spazms. Could be a loose connector under the steering column doing the same thing.

Earthing wires on eyelets bolted to chassis or cab metal also could be loose.

Had this happen to a 80 series the problem was where the alternator plugged into the main loom,needed to be cleaned.

In the 100 it would be alternator but the 105 doesn't have the computer smarts of the 100 so might be different.
Did you check the alternator output fuse?
Have you used a multimeter to see if the battery volts go up when you start the truck? That would prove the alternator is charging?

Lcool.org is the best resource for landcruiser problems.

All interesting comments as I've been having a similar problem with my 1992 HB30 Coaster (4WD). In my case the "T Belt", "Battery" and the "Filter" lights all start flashing or simply stay on for different time periods.
I've checked all the items and there's nothing wrong and as it's been going on for some years now, I've just ignored the lights.
I've always suspected a loose connection or a wire earthing out somewhere so I might check some of the above suggestions.

Gerry, possibly a bit different to the cruisers. With the cruiser, it usually is the result of no output from the alternator and its the computers way of telling you that you are running on battery only - but not for long.
Alternators do not like intermittent wiring and it usually kills the alternator so your problem is likely elsewhere.
