I recently had a similar interest in swapping to LED bulbs on the tail-lights and flashers, and appreciate this thread very much; thank you to all of your relayed experiences with the issue.

However, after reading this thread, I think I'm going to save myself from the hassle and fail to see these troubles as an improvement in any way. Hot resistors and the lamp out indicator light reaming even with CANBUS bulbs does not appeal for the nominal difference realized. That, and after seeing no amazing improvement with LED bulbs in other applications except for interior lights, all this trouble doesn't make much sense.

But what got me most was this; if you simply go with those that then constantly activate your "lamp out indicator light" and ignore it's presence - is that wise?

Meaning, I would rather go with traditional incandescent bulbs that last some 8 to 10 years or so at least (though I actually have original incandescent bulbs in a '68 Chevelle and '66 Mustang all around that have yet to burn out after 50+ years), than to ever have to want to take on the chore of replacing a burned out "lamp out indicator light" in the dash, assuming that these 15 year old cars are running incandescent "lamp out indicator light" rather than LEDs - no?
