Lighting
Colored Bulbs
The bulb must have a "DOT" or appropriate SAE stamp on it. Currently, there are
NO DOT approved "Red" bulbs.
- Vehicles that are equipped from the manufacturer with approved lenses which are clear and lighted by red L.E.D. lights will pass state inspection.
- Vehicles that are equipped with aftermarket lenses which are clear and lighted by a red bulb will be rejected. (Currently, there are NO DOT approved "Red" bulbs.)
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".
Equipment manufacturers have to self-certify that they meet these standards. DOT does not test equipment unless they act against those who don't meet standards. You should insure that the equipment vendor is reputable and that all equipment has a DOT or appropriate SAE stamp on it (or if not marked, keep the box that it comes in which says it is "DOT approved") and under no circumstances use equipment that is for "off-road or show only".
