I guess you could, be aware that most factory headlight washers are heaps higher flow than windscreen washers so go pinch the bits from a volvo or something rather than rigging up some windscreen washer bits
do you have headlight protectors? I find the dirt and mud seems to get under the protectors too, either way give them all a good wipe with rainex before every run, it will stop the mud sticking, or straight car wash if you arent going to be using the lights
WD40 in the guards and underneath stops it sticking there too
