Welcome from Utah.

While I don't like hids in stock housings, you would need a sealed beam conversion kit, then replace those bulbs. Sealed beams don't have changeable bulbs.

 

Getting a set of new housings tmw morning
its a k5 so do you know the blub type id need?

 

I have no idea, but the housings should say on them. Probably an H4.

h4 conversion with a 6000K hid h4 bulb is the best
