Not having seen your circuit. There should be a blue/white wire coming 
from your dimmer switch to the coil of one relay, and a blue red wire 
coming from your dimmer switch to the coil of the other relay. Both 
relays should have one relay contact to Battery, via a fuse. The other 
relay contact of the relay with the blue/white coil wire gets a 
blue/white wire from each headlamp socket. The other relay with the 
blue/red coil wire gets the blue/red wire from each of the two light 
sockets. Light socket black wire to chassis ground.

Sounds like you wired one headlamp to one relay and the other headlamp 
to the other relay. The Lucas wire colour code is your friend. One coil 
gets blue/white (high beam) from both headlights and the other relay 
gets Blue/red (low beam) wire from each of the headlamps.

And if your wiring kit doesn't come with the correct colour code yell at 
Moss for sourcing generic junk.
