There is no lighting coil on a pvl,so No you cant run lights.I like the pvl more than the dyna.But it is personal preference as well as set-up and purpose.
If you are strictly drag racing I say go with the PVL,but if it is trail/dune go with the Dyna.
Like I said though thats just me and you will get a lot of different answers.Some people have problems with both ignitions and will only run stock.
