Hey guys,
New to this forum, but I've been brainstorming a project for some time now.
I recently developed a set of LED taillights for the IS300, but there is one obvious problem. The current from the LEDs is substantially less than the standard bulbs, so it trips a rear bulb failure light.
I am against load resistors wired in parallel because others who have done the same thing have melted taillights.
Essentially, I'm just looking to have a small circuit to tell me when a LED module has failed (or fuse has blown, etc).
I've been eyeing the zetex high side current monitor, but I wonder if i'm missing something much simpler here.
ANyone have any other suggestions, I'm so deep in this perhaps a fresh look at the problem might yield better results. Also, modding the original sensor circuit is out of the question, since the chip was manufactured by Denso, and they won't release datasheets about the chip tothe public, but i do have part numbers if anyone has access or thinks they can help.
Thanks,
Nick
