Um, I think that's what I  tried to say. [Edit] <snip>, but the lights go solid color when locked in 4WD, and blink while they are in transition. [Edit] My bad - the color was stated incorrectly, but I had the sold/blinking behavior correct... which is the key pointIncorrect. The front lights will blink until engaged. All the lights will go solid yellow when 4WD is engaged. You might have to feather in and out of the throttle for it to engage, and the same to dis engage. The lights could also indicate a problem if you can not get 4WD to engage.
