I am not sure when this happened, but my landing and taxi lights no longer light up the ground. They come on, but nothing shows on the ground like it use to . Here's the hard part. the last time I know they worked was before I loaded acceleration pack and set up two monitors. I think they worked after doing those things, but can't say with certainty. Any ideas on what I might check, and yes the Aircraft landing lights illuminate ground box is checked. Thanks

Please Help. Any Ideas?Thanks
