Is there a round relay that will work for a 200 watt lamp load that I could just plug in for it?

200W @ 12V is 17Amps. I'm not sure what the rating on the round relays are. A square Bosch is rated at 30Amps.

I added the H4 head lamps with the 55/100W.

Know of anyone who would know?

Where would you "just plug it in"? The relay at the light is for the motor, not the bulbs. The bulbs are simply fused and don't have a relay.

There are two places that have relay set ups for higher intensity lights, Rally lights.com and Bus Depot.com. You should do that as the extra current thru your headlight switch will eventually cause you problems.
