Yes. If your motorcycle was manufactured after 1985.
No, but you will need to use hand signals.
No you do not need turn signals on a motrcycle in pa and MD other states not sure
It varies by state.
You don't need any lights in Guam!
In pa you dont need turn signals
Yes.
If you don't have turn signal lights then you must use hand signals.
Required by law (motorcycles manufactured before 1973 are not required to be equipped with turn signals.)
You need to remove the front grill to get at the front turn signals (and bulbs). A lot of work for what should be much easier.
The turn signals are not fused front and/or rear. If the rear are not working you need to check for power and grounds for the lights.
You need them to pass inspection, but they are not required by law on any motorcycle in PA. So once it is inspected you can take them off. I know, silly isn't it?
don't be dumb and drive safe kapesh
