LittleBeast and etl are correct. Like in my review a 3ohm on each side (circuit) will suffice for the front and rear lamps. I've tried "electronic" flashers and have had no luck with them. I didn't like the idea of the load balancers but they perform the best out of all the solutions I tried. that's why I included them in the review.

The only drawback that I can forsee, is that you will not know if a lamp burns out. Normally, if a stock lamp burns out, the flasher will have less load on it and will flash rapidly on the side of the burn out, giving you the tell tale sign of the burn out. With the load balancer installed, the flasher will not do that. Fortunately, I've not had a burn out since the original install in 2005
