I've searched many places, but I cannot find exactly what I'm looking for. All I want is to know the following: Do the LED turn signal replacements for the 7440(?) handle the dual voltage for running and flashing? I would assume yes, but cannot find the answer. Will I or will I not need resistors for the turn signals and/or the brake/running lights? Can anyone suggest good, bright, and exact LEDs to replace the turn signal and brake/running lights with? Thank you in advance.
