    tried them, they aren't worth shit when it comes to light output.

    I just bought some of these to try and will report back once I've assessed their quality...

    No sure about the e31 but I know on my e30, if you put a non BMW bulb in the turn signal it flashes rapidly (similar to when a bulb is burned out), replace it with a BMW bulb it works fine. If there is such a difference between the BMW and non-BMW bulb I would be cautious about doing the switch to an entirely new type of lighting.

    That has to do with the resistance difference.

    Would there not be the same problem with changing over to these LED's?

    yes it would, but some LED's have resistors built in to fool electronics, so no faster flashing or no error codes on OBC. These LED's are advertised as 'CAN BUS'

    Like I said earlier, Sick Puppy Motorwerks bought a bunch of different LED "bulbs" to retrofit the 850. Although they did light up, their light projection really sucked compared to a "normal" bulb. Not worth the time and money.
