Would like to know if there is any aftermarket company that offers a dual headlight convertsion for a 96 S1 Lightning.

this is what I found when I did a google search for S1 Lightening Dual headlights:

don't know what your fork size is but this says it will fit an S1 but it is more of a universal piece I think.

I'm not sure about the fitment issues they have, but you might contact the IronMachine guys about their product line.

Here's a link for a dual-headlight setup: http://www.ironmachine.com/product_info.php?cPath=47&products_id=57


Again, not sure if they have the right brackets to make this work with your model. But an e-mail or call to their techs will answer the question.

Good luck with the project and let us know how it turns out.

LSL makes a very nice billet setup that is very bright and well made, but very expensive. It can be viewed americansportbike.com

I went to HD and made them look up the part numbers/prices for the 04 buell lighting, the parts came to 210 for the duel lights, grill, bracket, bolts, and screen.
