I can't stand when there's a trip mine grenade in front of me and I don't know who's it is. Sure you can shoot it, which I often do in case it's the enemy's. But wouldn't it be great if it flashed a different color for teammates? I vote for green. EDIT: Apparently the grenade shines white instead of red when it's friendly. I can't tell... Vote up if you think it should still flash green!
