547.3215 FEDERAL STANDARD
Unless specifically prohibited by this chapter, lighting, reflective devices, and associated equipment on a vehicle or motor vehicle must comply with:
(1) the current federal standards in 49 C.F.R. Section 571.108; or
(2) the federal standards in that section in effect,
if any, at the time the vehicle or motor vehicle was manufactured.
Vehicle lighting equipment is covered in Chapter 547 of the Texas Transportation Code, Subchapter D. § 547.3215 - Use of Federal Standard. Unless specifically prohibited by this chapter, lighting, reflective devices, and associated equipment on a vehicle or motor vehicle must comply with:
• the current federal standards in 49 C.F.R. Section 571.108; or
• the federal standards in that section in effect, if any, at the time the vehicle or motor vehicle was manufactured.
The CFR will refer you to Society of Automotive Engineers (SAE) #J578, which will refer to several other SAE standards. Everything that complies with those standards is "legal".
I was unable to find anything “illegal” about down lighting being added to a M/C.
Did I miss a specific rule or prohibition of M/C down lights? I found the Federal rules
mainly concerned with light output, size, location, color, type for original equipment and
longitudinal axis/horizontal plane projection requirements.

 I agree you're not likely to get arrested for that sort of thing.  I have searched for the info  or a link several times with no success.  Sometimes I think I'm getting senile and just imagined it

Sometimes I think I'm getting senile and just imagined it   .  I am extremely sensitive to bright lights at night due to taking my ophthalmologist's recommendation for multi-focus intra-ocular lens implants.  I think they were called ReStor.  He told me the bullseye appearance and intensification of light issues/problems with the implants had been solved. NOT!  I just try to look away but eventually I think my night driving will be kaput! The new LED light bars are impossible to ignore. The lens also affect my shooting because I see multiple images of the sights. I just concentrate on the darkest images among them.  He also told me I'd never need glasses again.  Another lie!
