What length of night racing will you be doing?Personally i don't think the Stella set up would be enough light output for racing as i believe you would out run your light at higher speeds. Even with a decent discount,i doubt you would come close the the Magic Shine 1400/900 combo for light output.And only for a shade over $200 from Geoman, there's nothing out there that comes close in that price range.To put in perspective,you would need at least a Seca 700 for handel bars and a Seca 400 for the helmet to achieve similar light output.Even with your discount i'm sure you would be close to tripple the MS combo's price.Good luck!!
