So it is drawing noticable power from the engine. You may not FEEL it in the powerband, but the plug is not getting the same spark it was before. But, If it still runs good enough for you then it don't matter. My original concern was about cold starting. If it still starts well while cold then you're OK I think.
Your lights seem to work well, Good job.
