The prices that Burt( Ambiguous) quoted on his comment is almost exactly what I paid 3 months ago...So he's not making a much on these lights, and I can attest that its solid equipment thats held up thru wheeling,sno & mud, and extreme cold -20*...I installed mine in about twenty minutes, they are plug and play, I TTapped into my headlight wire so the DTRL's come on 50% dimmer when the headlights are on, which I suggest. I use the 5K bulbs and its way to bright to run in concert with your headlights. when using the turn signals the Amber lights up almost instantly(even in the cold), and return back to white in about 2-3 seconds. I also installed the 5K side lights which look really good with the DTRL's..might be a legal issue not running Amber in side markers, but havent had any problems with the Law. Strongly suggest that whatever lights you opt for, to be sure you maintain the same Kelvin output on all your lights.....
