lost dangly bit

I lost one of the dangly bits under the foot rest on my er6.
(Calling it a feeler sounds ruder!)
is this an important part? should I just get rid of the other one to match or replace it?
(probably have to replace the footpeg too if I do that)
my only worry is do I need them to get through scrutineering at a track day?
(Haven't done one yet but are planning one next month. they say the bike has to be roadworthy)
