In the Saga Edition of the Star Wars game, you have the option of buying decoy glow rods. They allow you to store a small item inside of them and they light up (fooling authorities).
The only issue is that they weight ~3 times as much as the regular ones and it should be blatantly obvious when a glow rod is a decoy or not.
Is there a way round this? And why is there this discrepancy?
