Impreza rear lights

[MattB133]

I have a 2008 Impreza RX and want to make it look more like an STI,
my main problem is the rear lights because the right tail light has a
single red filter over it and I can't seem to find anywhere that stocks
the replacement unit. Do you know if it is possible to remove the red
film, or know of anywhere that will sell me the clear unit because I couldn't find the answer to my queestion or a light unit when I Googled them?

Bellow is the photo of my drivers side light with the red film on it.

And bellow is the clear passenger side light with no film on it.

Thanks

Matt
