[TR] 1972 Triumph TR6 - blinker problem

[DAVID MASSEY]

It looks like the flasher unit is a current-sensitive type and needs at least one incandescent bulb to flash.  
The dash indicator makes perfect sense since it is an incandescent bulb itself.  It works by providing a current path from the active flasher circuit to the other.  The dash bulb requires much less current to light than the actual turn signals so the current going through the dash bulb flows through the inactive turn signal bulbs but the current is too low to light the bulbs.  Replacing the incandescent bulbs with LED's discombobulates the voltage distribution in the circuit and it is quite likely that both turn right and left signals were flashing with the turn signal stalk in either position.

This makes no sense to me.  Apparently in the last few weeks I replaced the front bulbs with LEDs.  The rear already had them.
 
  
 
Replacing the front bulbs with analog bulbs fixed the problem, and, as a bonus, the green trafficator light is now working.  I haven’t seen that for years.
 
  
 
Now the blinkers work as they should.
