Since you have SIZE(16), it will be encoded in 16 bits with no length field.
If you had instead omitted SIZE(16), any trailing 0s would be omitted, but
there would then have to be a length field.
Note also that underscores are not permitted within names. There are
other ASN.1 syntax errors but it's clear what you meant.
