[ducked]

Back in Taiwan trying to get car ready for its overdue inspection

I replaced one working but badly silvered LHS bulb with a 12V LED because that was all the shop had, and the disintegrated wing bulb holder with some small (I think 5ma 3.2 V) LED's in series with a 200ohm resistor in a connection block. 4 LED's worked jumpered directly to a fully charged battery but could only get 2 in situ on the car, presumably due to voltage drop through the dodgy wiring. These LED substitutions didn't seem to affect the flash rate

Piggy backing a non-working side RH light off the front light for Power and Earth caused both sides to flash, I suppose because this earth wire was shorted to LH power. Giving it its own earth wire to a nearby body screw stopped this happening.

However, the flashers are also supposed to be running/sidelights, I dunno how this function is achieved but on the RHS it isn't

The hazard switch now works. Activating this in the running light position gives a non flashing, but rather dim, running light on both sides.

That;s almost enough, but the inspection people may not agree.
