Headlights, interior lights, brake lights?

How quickly do they pulsate?

Id stick a volt meter on the battery, it could be a the alternator or the voltage regulator on its way out causing fluctuations in voltage.

You do know that its normal for the indicator lights to pulsate

agreed above - get a voltmeter and check.. could be a fault or not providing enough power from alternator.
Have you had a flat battery yet?

ok did that and yes voltage is going between 8 and 14, 13 years old, and 500k on the clock, i guess something had to wear out

Did you say 500,000 kms on the clock? I would say it would be wearing out. For starters is alternator to check out and replace relays etc as they would have poor contact inside them.
