I've just fitted an LED tail light bulb (not the the LED board, but the large circular bulb) to my 1150... and it lights up the dash warning triangle. Fit a normal bulb and it's off, the LED one back in and it's on... I'm baffled; any ideas..?
you could either fire off a message to 'techno' on this site who is an LED guru. Or simply pop down to Maplins and ask them for a resistor that will fool your IBS system into thinking that your LED is drawing the appropriate voltage/wattage (or whatever it is) a resistor is only pence.
