With the "new" lights installed, bypassing the flasher unit by "shorting" from the power terminal to the light terminal lights both the front and rear light in a continuous glow.
OK !!!I've solved the problem with the non-working aftermarket turn signals. The mistake I made was to assume that the wiring harness BLACK wire was the ground wire and the striped wire was the power supply. WRONG!At least on my G5, it is not.Connecting the black wire to the wire coming out of the new lights threaded stud and touching the striped wire to the new lights case the light blinked merrily.
