147 reflector HID kit - question

Got a 147 pre-facelift . I've been trying out different bulbs, currently using Osram Silverstars. Great light,but i'm after the xenon effect. I've read about the H7R and H7C and also something about CANBUS headlights on 147 aka will throw an error with HID bulbs. The canbus thing, true or false? If true, how to fix it?
Anyways, my slight worry since i'll be ordering from eBay is fitment. I saw on a thread here that H7R bulbs sometimes don't clear the metal plate on the reflector on a 156, i'm interested how it is with the 147. Perhaps standard H7 HID bulbs fit on the 147? Any input is appreciated.

No canbus errors for the headlights - you ought to be able to spot a blown headlight pretty easily, so you don't get a dash warning for these ones.. Hence no errors when fitting a HID kit.

Not heard of problems with fitment of the H7R's myself, and mine fit no problems in my GT.

H7R bulbs are designed for reflector housings (hence the R) - they have a metal shield attached to the bulb directly to severely reduce the amount of light that's scattered upwards that might otherwise cause dazzle to oncoming drivers... Other's run standard H7's and claim to not have any issues, but I chose H7R's just to be sure.

I would highly recommend getting a relay/harness at the same time to power the HID's directly from the battery rather than through the OEM loom... There are some reports of funny behavior after retrofitting HID's to the OEM fittings as they can draw a lot more current on start-up.

Glad to hear no canbus error-free kit is needed,given the increase in price. Browsing through eBay, I might try the H7 standard bulb and get it properly alligned. How's the light from the H7R's as i've read that while it dazzles oncoming traffic less, it produces less light as well?
Are you running 35W or 55W? So far ,i'm leaning for 35W simply because 55W might be just too much for oncoming traffic, but what's your position regarding it?

Light level is OK.. Certainly doesn't blow the original halogen's out of the water mind... Route cause is the pants reflector design!

I've got a set of 35w lights, couldn't comment on the difference in light output verses the 55w however...

I do have another set of headlights, a set of Mini H1 Morimoto projectors, new ballasts etc. in the garage.. I'll get round to stripping them down and fitting a proper set of projectors soon.. Should be a big upgrade!
