Hi .

This is a bad alternator voltage regulator malfunctioning .
Do a alternator output test with the engine running should have
14+/-0.6volts , you may have to do a running test as it maybe intermittent .
Check all battery connection and main fuse for corrosion .

This is a tricky one as when we had this issue we could not find the issue until the alternator regulator eventually stopped working.

Do the voltage test and a running test if the voltage is good and when the lights come on check the voltage at the same time if its lower than the 12 volts replace the alternator .first check the battery .

Need further assistance then please get back to me with the reply box and not the poor or bad service button .
