Single toggle relay is what I was thinking, just did a poor job explaining.First, I should mention that this only controls the hood marker lights (not the corners, rear, or mirror markers). If that's all you are interested in switching, then ok.
Also, I don't think you want two separate relays. At some point, you could be double-feeding the circuit and likely fry something (unless you install inline fuses, then you'd blow the fuse). If you wanted to do this, you'd need a changeover relay (one that toggles the power source).
