Robert asked: I have a moped. I’ve installed a flashing red 3″ light on the rear. Is this illegal? if so, would the solid light be too. It does both.
The use of a flashing light on a moped is not lawful, but it is permitted on a bicycle.
s. 316.2397 – Certain Lights Prohibited; Exceptions
(7) Flashing lights are prohibited on vehicles except:
(c) For the lamps authorized under subsections …. s. 316.2065 (Bicycle Regulations)…. which may flash.
There are exceptions, none of which apply to mopeds.
The lighting requirements for mopeds are found in federal regulations, and are beyond the scope of this site.
s. 316.46 – Equipment Regulations for Mopeds
No person shall operate a moped that does not conform to all applicable federal motor vehicle safety standards relating to lights and safety and other equipment contained in Title 49, Code of Federal Regulations
I suggest contacting a moped dealer or law enforcement for those requirements.
