I know this is almost a weekly topic, but I am easily stumped. Added LED turn signal lights to replace incans. Found and bought an electronic flasher that does not need a load to work. The rear turn signals work fine, the front signals sort of work, but instead of on-off-on-off they just change intensity, dim-bright-dim-bright. Before the change, the front lamps (LED) with the incan lamps on the rear, worked fine with a standard bimetal flasher. I am just not sure why the fronts stay partially lit. Any ideas?
