Replaced amber lamps for LED bulbs – no more “fried eggs” – very reasonably priced ($6 on ebay shipped direct from Hong Kong!) – only problem was the flasher ran double speed because the clever electronic flasher “thinks” the lamp is blown because the current draw is too low.
Brought a new flasher relay from the “Zone of Auto” and with a small modification now blinks at the regular rate… I modified the R/C circuit with a pot so switch back and forth (if required). You can buy special LED flashers (for more money of course) – but five minutes and a soldering iron also works.
Found out the issue with the nearside running light – rotten fuse in S2 position, brought at a complete replacement set, the others are a bit crispy.
