Re: LED tail lights
ok, here's the follow up: after installing the LED canbus bulbs, on initial engine start up, no indicator lamp. approximately 30 seconds or so later, the lamp does come on. apparently, the ECM (or whatever determines a lamp out condition) initially accepts the resistor level built into the can bus bulb but eventually recognizes that there isn't enough load on that circuit and produces a fault, triggering the indicator lamp on the dash. i asked a couple of people who should know what was up, (much more so than me) and they indicated that each manufacturer may differ in the load necessary to trigger or not trigger a "fault" in the system and the only solution would be to add in a 6 ohm resistor to that application. apparently, the resistor level in the "no error" canbus bulbs is pretty standard, and even though there might be differences in different bulbs it isn't worth the time to experiment with numerous bulbs to see if you can find one that might actually work without a load in the line. i'm sure there are plenty of folks here who may have played around with the same thing and many persons with lots more knowledge than me might be able to contribute an alternate LED bulb usage solution if there is one.
