I've fitted my great new DRLs. They have a box of tricks that connects into the side lights so the LEDs dim when the lights are on. The driver side is intermittently showing the bulb is out. When this happens the sightlight bulb does not light, the LEDs that side stay bright and warning light on the dsah comes on. The passenger side never does this. I thought it might be the scotch lock on the connection to the side lights but I've swapped that out for solder and it makes no difference. Other times it works fine and everything works as it should.
Anyone know what the expected resistance value is on that circuit (if that's how it works) ?
