yeah the most I saw them for was $20 (E-bay) and $5 for the 30A relay/harness so it was a pretty cheap upgrade considering the price of a new set of ballasts.
The function of the delay is to keep power from the whole light circuit (if you don't have any power to the low you won't have any to the high) essentially doing the same thing as pulling your fuse from the block (for 1-90 sec.) until you get the bike started and then re-inserting the fuse.
