Probably a bit late to the part here. Of course all lights need to be full Canbus, Even those which say they are are not neccesarily so and will still emit a low light. (Thinking more internal here) However not all are as described.
I have found this out myself and have also found some really good fully Canbus with a high Lumens output. They work perfectly in my car.
I purchased off ebay from the link below and they provide very good service.

They have a good light output and no Canbus issues, If you buy 10 I think they are about £1.00 each which in my opinion is good value.
Another very useful addition to my car are some custom made LED boot lights which make a massive difference.

These have made a massive difference to the light in trhe boot and are very simple to fit. I just broke off the stalk switches to be fair. Work perfectly. Good value as well and they accepted my best offer.
The majority of internal bulbs are east to change, although you might want a proper tool removal set for main central internal cluster. to avoid scratches.
Overall massive difference.
Might be too late, but hope this helps some,
Peace,
Andy.
