Does anyone remember the LED drop in upgrades for the Striker-VG?

[vleong1]

I have a Striker-VG that I'm going to sell but don't remember what LED drop in upgrade it has..

Anyone remember the upgrades available for this light?
Also did the upgrade still work with 2x CR-123A's?

I was not aware that any type of drop in was around for them.
