I think Plane has me convinced not to muck with the turn signals, but I'd like to convert the marker, brake and interior lights . The savings will come in handy if I decide to install an alternator switch.
The "CANBUS" system is like a more advanced version of the OBDII diagnostics system found on cars after 1996. Essentially it means that most things (bulbs/abs/engine sensors etc) are all monitored and generate error codes if issues are detected. The low draw of LED's can cause false error codes. Remedy seems to be via inserting resistors into the circuits.

Thankfully, my 1994 car doesnt have such issues

2, conventional flashers work by routing the turn signal circuit current right through them,through their bimetallic contacts which bends/curles from the heat opening the circuit then quickly cools re-gaining it's original shape and making contact again and the cycle repeats. This is calibrated to work with the current draw of the original bulbs.With LEDs in the turn sig.circuit, the current draw is so much less that it will never brake contact and flash.

The more I hear, the less I like the idea of the indicators
