yes, I'd say you have H7 bulbs [HID or Xenon], meant for BMWs, Audis and rice rockets .... why?? you should have T3 style [which may have a '2' at the top]
I believe the standard bulbs for your truck were about 110/90 [watts high and low beam] - as suggested above, if you want to "upgrade" to "modern" equipment, you need to do it the way the modern parts were meant to be used, with a relay .... is your problem on high beam?? not suprising
