You can't. You'll have to buy the headlamp. The bulbs are not replaceable and that's simple just 4 hex screws on the corners.
Not sure about the answer above, but I have a 1990 1500 and it does have bulbs in plastic lenses instead of the whole square bulb assembly. On mine, pop the hood look down the back of the grill wall and on each side of the radiator and you should be able to see the bulb retainers they either twist and pull out or have a lock collar that twist and unlocks, you may have to yank the battery for the passenger side. This applies to only the bulb type in the plastic lenses, if its the old whole square glass bulb then the answer above is correct.........either way, not real difficult.
there are actually no screws. pop the hood and look for the plastic tabs above the headlight...one on each side of the headlight. pull them straight up and voila'.
open the hood and there is a bracket with 2 screws take that braket off the take off plastic cover then you can do the job

There are two clips on the wall that holds the headlights. Push the clips away and pull the headlight housing out.

more then likely w/ no more info then is provided there is a silver rod on top of the headlight pod you slide to the side then the whole light will come out and you can replace the bulb and reinstall.
Yes, you sure can.
Open the hood, remove the two locks that hold the headlight assembly in place, with the two locks removed you can wiggle the headlight assembly out and gain access to the back side of the assembly to remove and replace the headlight bulb.
