I've done it twice, once in Georgia and once in Texas. I added aftermarket light kits to both bikes, showed the receipts for the DOT approved kits and received the titles, tags and registration. Getting insurance was more painful then getting the plates.
Both were late model 4 stroke off road bikes, one a Yamaha and the other a KTM.
I found the information "how to" and the place to order the kits on the off road sites.
