On an 01 dyna are these just plug and play? Or do they need a load protection block in line near the battery?

 

Yes,I used a biketronics load equalizer on my old 01 dyna,plug& play

 

I have an older Custom Dynamics turn/brake signal flasher module and LED tail light and turn signals. It is all plug-n-play with incandescent front turn signal bulbs. When I installed LED turn signal lights in the front, I had to install a load balance to get the turn signals flashing correctly. I had to modify the wiring to install the balance resistor.

 

Stupid question.. is the difference between the two lights all that noticeable?
