Be aware that this is NOT a recommended change to your Fatbob, ask your HD dealer before installing, the CAN Bus may not cope with the extra power, I have been warned off doing this. They do look much better than one light on though.

a couple of bikes on here that have been done for some time and no issues. and a heap of them in the UK also. Are you saying the dealer is telling you the wiring setup and system is different on our bikes to the USA model.

I remember puttin more powerfull globes in bikes of past and was told would make stator an rectifier do strange things like fuck up ,also fuk up other electrical componants that make up everything work and we put in some sorta containment fuse or gadjet that would fail first b 4 meltin brain of makin bike work ,not much good wen push starter an yep motor spinnin but she no go ,an yes bike did stop on ocassion but i knew it was fuse thing we had set up ,so just replaced an way we goes but he did warn that maybe oneday damage may occurr somewhere in circuitry maybe SHINGLES
