A street legal dirt bike is any dirt bike that has a four stroke motor, head lights, brake lights, turning signals, a spark arrestor in the silencer, and street legal on-off road tires.
Turn signal switch is melting...replace the turn signal switch in the steering column.
A strobe signal is the name for any signal that flashes on and off. For example the turn-lights on a car. Certain lights such as some leds aren't actually on all the time but flash faster than the eye can see, that is also a strobe signal.
If neither signal light works, the flasher may very likely be the problem. The hazard lights and the signal lights work off different flashers.
the end off the turn signal switch
WigWag lights - usually used on emergency vehicles when one headlight goes on and the opposite one goes off (flashes)
Check the Hazard warning switch
No it is not illegal, as long as you have operational tail lights, brake lights, signal lights and a plate light.
I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.
Most likely poor wiring.
If you mean you have amber fog lights, and you want them to work as turn signals whether they are switched on or off, I'd use an XOR circuit... A=Fog switch B=Flash signal AB Fog 00 Off 01 On 10 On 11 Off aka XOR -Matt
multi function switch( turn signal, lites etc)
