286 or 509t bulbs. They seem to be the same lol. Loads behind the clocks, can't remember exactly but over 10. 2 in the time/temp display. 2 in the heater panel - but the newer heater panels have 'reverse' 509t bulbs in them.
Don't know if different phases have different number of bulbs but this is the ph3 HDi clocks.
