I cut a piece of aluminum to make the lens screw bracket.(Front left lens) Couldn't find longer thumb screws but close enough.
I replaced the green led in the lens and added one to the other lens. Dimmed them down so I didn't go blind. I used plastic card and filler to make the raised ring on the front.
I built a different battery door(the round one) to look more realistic and used a mini push button for the switch. Might mod this to look like the real push/pull switch later.
Added a flashing led for effect and to indicate power.
