Those with the fan and heat sink on the back will not fit the Spyders.
JC, that may or may not be true. I was concerned about the installation on my KTM also. When I recv'd the light assembly I was stoked to see how small the entire unit is. On the KTM, since it is an AC system, I also needed the little black box. If it were DC that black box is not needed.
I hear what you are saying that it may not fit, I am more of the opinion it may be tight, or if the rear cover were modded with a hole saw, these could be an incredible light system.
For the KTM, I have one LED "bulb", 3600 lumens and it is stupid illumination.
On a side note, we run the optional BRP HID headlights in our 2014 RTs. BRP stated they were applicable to model years up to 2012. Well the headlights themselves were an easy exact fit. The concern came down to the ballast mounting brackets. Suffice to say, and I know not everyone has access to tools or ability to make upgrades themselves, but these HIDs are a solid tie for best mod with the Corbin seat.
At some point, I would like to hook up with a couple of local riders and find a dark road to compare. HID vs LED vs OEM.
BTW, if I ever burn out one of my amber fog lights, I may try the forced cooled LEDs in the fog location. I cant imagine how bright 7200 lumens as driving lights will be.
