I was running out of things to hang on this bike and came across a set lighted rear signal mounts with smoke lens (68624-04) on eBay for a too good to pass up price. Doing the swapover wasn't too bad of a job though it might have been a tight fit in the tail light housing if I still had the stock light socket in there.

The smoked lens version blends in very well and you'd probably never know they were there unless turned on. There's another socket right next to the left turn signal socket in the tail light mount, and this accessory is what it's there for -- plug and play.

Suffice to say they do add to rear visibility. They get brighter when braking. I've tried to take comparison photos of it, but those 136 LEDs of the Radiantz tail light array are so darn bright that it tended to over-power the camera. You can get a general idea from what I got.

I did the same with the smoked lens and love them. Definitely increases viability.

 

I have that with the clear lens. Since my objective was to increase visibility, the smoked lens didn't make sense to me. But I think, the lighted signal mounts are one of the best "unknown" accessories HD has.
