Q about LED bulbs replacements for TV stop/tail/turn lights

I guess nobody has run into a problem yet ? Changing the 'load' on the electrical system on many vehicles
sets a code/fault,something in the truck is monitoring the lights and tells the driver when one burns out .
I have a turn signal that has become sensitive to moisture and drives me nuts.
If you want to add chicken lights or any light change means a trip to the dealer to tell the computer to 'never mind' :-)
