If it is a dirt bike they do not require a headlight, but if it is a road bike then yes all motorcycles need a headlight by law.
Running Lights or Vanity Lights.
No, The running/parking lights go the light switch, the horn is on it's own curcuit thru the fuse panel.
What are front rear running lights? If you look under the hood on the left side of the engine compartment there is a big long black box with all of your fuses and relays.
1st move the light switch to the desired position. 2nd PULL the switch gentle towards you. There are two positions for this switch. The first position or click, will turn on your front running lights. The second position or click will turn on both your front running lights and additional lights in the rear. You will be able to tell that you have activated them by the icons on your dash that will inform you they are on. To turn off simply push the switch back in. (Actually, those are the FOG lights, front and rear.)
If all the running lights (front & back) are not working I'd start by checking the fuses then onto the headlight switch
You probably have a rusted or disconnected ground wire to the running lights and side markers.
the running light circuit wire is brown. If you are looking in either the front marker lamps or the rear tail lights.
The fairing.
Not the cool ones. Colors are limited. White/Amber visible from the front. Red from the back.
Illegal color of side marker lights. If present, must be yellow in the front and red in the rear (25106, 24003 VC).
I'm not sure I understand your question. DRL stands for daytime running lights. Your daytime running lights are on the front of your car; when you are driving, even if you have the headlights in the off position, the DRLs will be on. It's a safety feature.
General Motors made the '68 Camaro'. '68 Camaro' had more pointed front grille and divided rear tail lights. The front running lights were changed from circular to oval.
