What I ordered from DDM:
Apexcone Raptor 55w, 6000k big ballast.
I too waited a couple of weeks for my delivery, but they did finally arrive. Installation was straight forward. I used the online instructions over the paper instruction included with the kit. Online has pictures, and you know what they say about pictures....
My first impression is that they are definitely brighter than than the stock lights (I have projectors btw). Street signs are MUCH more visible. The difference is very obvious when driving next to another car and comparing the light output and pattern.
They are a bit bluer (not ricer though) than I would like, certainly tolerable, but if I were to do it again, I would order the 4500K.
No error messages what so ever.
The kit includes some extra connectors which are not required for our install. It is a bit of a trick finding a good location to place the big ballasts. The extra connectors could be used to lengthen the stock wire bundle, giving you more options on where to place the ballasts. I used double sided tape from 3m, not the stuff included with the kit. I had read somewhere it was not the highest quality.
Happy with them, and will probably do my fogs in the near future, though they will be 35w, 3500k.
Great bang for the buck!
