2002 Tacoma new headlights and bulbs problem/questions

Hi I have a 2002 tacoma that I recently bought and I ordered new spyder headlights for it last night and did a bunch of research and realized only h1 type bulbs fit in spyder headlights, and h1 type bulbs are single filament bulbs so I won't have a low and high beam, I haven't gotten the headlights yet so I don't know exactly how it's gonna work but I know my truck has one bulb for the high and low beam right now, is there a bulb that will fit in these spyder headlights to make it so I will have a low and high beam again? Or can someone clear all this up to me because I know the basics about head light bulbs but I'm stumped in this situation, and does anyone have spyder headlights for a 1st gen tacoma?
Thanks a bunch!

 

SUPERBRIGHTLEDS.COM has a tech person online. They are lighting wizards. I'd wait until the lights arrive and then see exactly what you might need.

 

can you take a pic of the assemblies you have?
