Dim Revi - only on the Bf-109E-7

[Blitzen]

This may be posted incorrectly- forgive me, but:

Whether the Mods or on or off. the gunsight illumination is very dim, but only on the Emil. On all other German planes the gunsights as bright as you might expect.I've tried using the Revi mods but they don't affect the brightness one way or another.Do you have any ideas or solutions?-thanks!
