I've seen a few people do this and was wondering if the consensus was that you'd find it useful or confusing:
As you're driving an emergency vehicle not code 3, and as another emergency vehicle that is driving code 3 is approaching, as you pull over and stop you also activate your emergency lights. On the positive side, this advises other nearby drivers who may hear a siren but not see the lights that they do need to pull over, and on the negative side it has the possibility of confusing the other emergency vehicle operator. Obviously you don't use your siren, you just activate your emergency lights to give other drivers a better chance of seeing some warning signal before they get hit by the other ambulance. Would you find this useful, or have you done it yourself?
