Brighter Metering with Bronica EC TL

Hi,

I just got a Zenza Bronica EC TL which seems to be in great condition. Metering seems to work fine, too. But I noticed that it sometimes is hard to read when shooting outdoors. Right now I try to read the lights through the loop which is a bit difficult to point it to the preferred area of the image.
Is it possible to make it brighter or better workarounds?

Thanks,
Arvid
