No, the signal wiring is used to drive the relay not source it. The bulb is drawing about 2 amps and the relay coil in parallel will draw about 70 milliamps or 0.07Amps which is diddlysquat compared to the 2 amps. The actual load for the cornering lamp is from its original power source and through the relay contact.
We're probably thinking on separate wavelengths but I suggested two relays one for each side for at least two reasons:
1. one cannot tie the two signal light signal together to run one relay as both signal lights would blink on either left or right turns, unless you use a diode in series off of each signal with cathodes together on one side of the relay coil and the other side of the coil to ground. For me as a electronic engineering technologist diodes and things electronic are plenty, but I do not know the resourcefulness and abilities of the OP so I try to keep it simple to what he might have.
2. one wouldn't have to run wires back and forth across from the two sides for the signals to drive the relay and the wiring for powering the lamps off the contacts. Essentially all could be done right at the lamp with minimal wiring.
I've got to shut down now and fix this stupid keyboard as the letter "o" is being finicky and creating to many typos to edit befre posting.
I'll try and draw up a schema of what i mean latter.
