Hi all,i bought mu PMDG some weeks ago, i have the problem below:when i turn on the inbound and outbound external lights, lights on left wing is flashing (right lamps are ok). i haven't solutions. I noted that also smoke from left engines come out discontinuous.somebody can help me... tnks

In an attempt at not creating a new topic on something that's been mentioned one hundred times over in the past, I chose to ask here.  I am having the most difficult time trying to figure out how to increase the external lighting on my PMDG 747-400.  I have searched on the web, asked other members, read the aircraft manual and cannot find anything that would give me some direction on how to increase the candle lighting on the external lights.  Additionally, the wing lights are no longer working.  I don't understand why???  I haven't touched, or changed anything on the aircraft's configuration file to merit the problem.  Does anyone have a fix for this?  They used to work just fine before but now suddenly they are almost non-existent.  PLEASE HELP!
