Late as usual Richard but would
these dual colour CANBUS bulbs work for you if you didn’t want to use resistors?
Unless I misunderstand I’m not sure that the L691 base is any shallower than the L794? As far as I can see they are the same. I just transferred my original L794 reflectors and L794 lens (white) into the new L691 dual bases.
Thanks for reply Rog. Yes those LED's do look as though they would do the job. High price and location in USA puts me off though.
Thanks for pointing out but agree I could simply use the twin contact L691 base and add the deeper L794 clear lens with reflector and longer screws which I already have.
I will probably bide my time until something similar to those on your link become available in the UK. May give Duncan at Classic Car LED's a call although he didn't list any CANBUS dual colour when last checked.
The extra feed to white position light I would probably take from the existing unused wing light feed each side.
