You might be able to use automotive lamps
You might be able to use automotive lamps, but the fact that you asked suggests you may not have the knowledge to make this modification without problems. When you order a light that is made for your model motorcycle, you get one that has been tested on your machine. It is the correct voltage, draws power that your bike’s charging system can handle, is mounted in a way that will not compromise handling, and has directions and connections that mate with your electrical system. Do you know what load the charging system can handle? Where you can safely tie into the wiring harness without compromising electrical performance and waterproofing? Answer those questions and you can probably use automotive lamps.
