I think a better solution is multiple relays. If that single relay
fails, you are suddenly in the dark. The overkill solution is 4
relays -- 1 for each high and low beam. Plan B would be 3 relays,
1 for the high beams, and 1 for each low beam; if the high beam
relay dies, you still have the lows. If a low beam relay dies,
you still have the other low beam.
Here's a simplified diagram using 1 relay for the low beams, 1 relay
for the high beams:
