Hi! I have a BT7 Tricarb in pretty much original condition, positive earth, dynamo, original regulator and so on. As the high beam and charging warning lights are very dim and difficult to see I plan to replace them with a blue and a red LED. I have found a silicone LED holder that fits nicely in the holes in the back of the instruments and with two cables that would make it possible to use them even with positive earth (by simply connecting the + cable from the holder to earth). I am however not sure if the charging system will work with an LED instead of a filament lamp or if it depends on current being able to pass through the lamp (which an LED obviously will not allow). Has anybody tried anything similar with success or has enough knowledge of the charging system to confirm whether the conversion would work?
Cheers
