I just bought a new HK 45, The test shell has a test date of 2006 and on the gun case it has a date of 2008(IN GREEN). Is the 2008 date they installed the night sights because of the green color on date? Also how long should the night sights last? If it helps the night sights say tru dot.

I dont know what those dates mean, but tritium has a half-life of just over 12 years.
