I have a 2008 RSTD and want to add spotlights. I purchased as set that were original equipment to early 2000's Indian, which has the turn signal built into the bottom of the spotlight housing. They mount fine on the RSTD spotlight bar. Does anyone have a diagram of how these get wired into the right circuit? I have seen where RSTD owners have added a toggle switch for on / off. Where do folks mount that toggle switch? Any help would be appreciated. Thanks. R.
