Yes, don't want to confuse people by pushing the turn signal lever down and having your right front signal light flash! Or lift it up and the left one does!Must be the case. Other indicator was having the drains down. I had that part right but the lights on the wrong side. They are marked "L" and "R".
And since the comment was about money on the truck, no problem, right?I could still see with the old sh!t. I replaced because my wife had made a few comments.
They are HIDCould possibly be a mis-seated lamp, being out of focus and reflecting distorted, which would cause a shift in the wavelength (prism effect) and make it look yellowish. But I agree with @Will L. with checking ground, lower voltage makes halogen bulbs look yellowish. If HID, bad ground would make lamp ignite in sputters and spurts and go back out before restriking the arc, or trying to again.
