Sorry Privy, but your top case looks exactly like my Astra Coocase right down to the silver stripe going around the front half. And I also have the same exact side cases as you, buddy. Givi's.
The topline Coocases like mine come with lighting that comes on with the parking lights and brightens with the brakes but they're just two leds (maybe 4, I might be wrong, don't spend much time staring at the back of my bike while it's moving) which could be brighter. No kit needed.
If I could put lites in the Givi's I would feel a ton better about those idiots behind me so I better check out them kits too.
As far as the HIDs. Like I said before, I have a ultra-slim Xentec kit off Fleebay, 5K 35Watt, for my low beams only. I also bought a Raptor 55Watt 6K kit from DDM for my wife's Dodge Avenger.
I haven't had an issue with my Xentecs on the bike except they aren't as bright as I expected. I think I will get the 55Watt kit for the highs eventually.
As for the DDM kit I have on the wife's car, I had to put a relay in to try to keep the lights from flickering. And the wife said there are still times when the lights go out for no reason. This was the brick style ballast that DDM states are bulletproof. Granted, I may be experiencing an issue specific to the Avenger since a lot of vehicles have complex lighting systems, but I am really at a loss as to why I'm getting a flicker with a 40amp relay and heavy wire supplying the ballasts. As far as the performance of the 55Watt kit, they are bright as all hell!! me likey!
So at this point I would not stand behind the DDM raptor kit. Their ultra-slim kit may work better. And I only add this because someone at one time wanted me to report my results.
Again, the 35W 5K, was not too much light for my tastes and I could have used more. So far after two weeks of commuting to work everyday, I haven't had one person flash lights at me, which is a good thing.
