Bumping this thread - replaced the backup lights with 1156LED equivalent which is an awesome upgrade, but before I ordered stop/tail lights and rear turn signals, do I need to do anything for the turn bulbs or is it plug and play (i.e. I know you need to deal with wiring issues for the front turns, I am only looking to upgrade the rears) and also any issues with the stop/tail lights (1157 style) or is it just a straight swap?
