Aeroplane Heaven P-47D Nav. Light Brightness

[Twice43]

I am flying the P-47D in P3D V4.3 & attach a shot showing the nav. lights.
Are these overly bright, or acceptable?
If the former, is there any way to adjust them?
(At the moment the cockpit Nav. Light switch flicked to 'Off' does not turn them off)
Thanks
