Texas Laws Regarding
Over glow and Under glow lights
Texas law does not restrict additional vehicle lighting which would include neon overglow or underglow. Therefore we conclude that in Texas neon overglow or underglow is legal, So it appears all models of Glorails are legal in this state if you follow the following restrictions:
Do not flash your glorails unless in an emergency for example changing out a tire on the highway
