I have a 78 yamaha, the stock lighting doesnt have dot ratings. I was looking to replace all the lighting as I modify it, but most of the cool stuff on the interwebs isnt dot approved.

It was registered prior so it didnt need an inspection. Are there exceptions to some of the bike laws if the bike is vintage (beyond a certain age)? Funny thing is a lot of the non dot approved lighting are with LED's and offer brighter and more reliable lighting.
