What does "20/40 amp" mean? There are two contacts, one normally
open, one normally closed. You can use only one of these (normally
open). Is each contact rated at 20 Amps? If so, this is enough for
two 100 watt filaments (both high beams, for instance), no more. If
you wired the two low beams and two high beams to different relays,
these would be able to handle the current.

Price seems fair.
