I'd suggest you voltage drop test every part of the circuit that you can - e.g. from bulb to holder, from holder to any harness connectors, from connector to next accessible part of the harness. You need to have the circuit loaded for this. Basically measure the voltage between any 2 points & where the resistance is low (as it should be) the voltage drop will be almost too low to measure. Test the +'ve and -'ve sides of the circuit. A voltage drop > a few mV would suggest a poor connection & might lead you to find the 'green crusties' causing a poor connection. Either that or you may have a short to ground somewhere if a bit of harness has rubbed. (Not totally sure that would cause the symptoms though).
You could jump the contacts on the repeater relay block to give a constant feed to the indicator bulb to make things easier. You'll need a multimeter (a cheap one for a tenner will do the job) and a length of wire with some alligator clips attached to extend your multimeter leads.
There is absolutely loads of info on the web about doing this sort of testing. Just Google 'voltage drop testing' & read as many pages / watch as many videos as you dare. Good luck!
