I tryed running them blue bulbs and they got so hot it melted the adapter plug. Had to run home with the highbeam on thru the city since of course it burned out at night. I still run one for the highbeam since I dont run with that on that much and they do seam to give a better view at night but for the headache Im thinking its about time to look into a hid kit like all the rest of the guys on here
