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.
