The indicator bulb (25w ~0.25amps) has a split loom and takes its own ground wire 1.5mm2 , while the main beam+side light and dipped light share a single ground wire 1.5mm2 inside.
I was thinking to join the two ground wires at the dipped beam and double the amps available.
The existing wiring is stuggling with the Phillips brighter bulbs and noticeably dims, also the copper used is poor.
Having recently seen quite a few smoking lights and dead looms on the forums, you have to split open the housing to get access, or you run a whole replacement loom externally to the backs of the fittings.
