Hi everyone, I'm designing a few tail light circuits, one for brake lights and one for turn signals. Keep in mind these circuits will be completely sealed in the tail lights so I won't be able to easily adjust components or replace broken components like fuses.
(1) Do I need to worry about lightning-induced overvoltage in automotive applications? The only concerns mentioned in articles on this topic are electronic discharge and load dump from the alternator. The wire used for my harness is about 20 AWG and the rest of the circuit is on a PCB.
(2) The turn signal is powered by a 12V square wave coming from the central electronic control module (CECM) in the car. Would this CECM typically have a built-in overvoltage protection circuit? Or would I still need a voltage protection circuit in my tail lights anyway? I can't find any information on the topic. The car is a 2011 VW Golf. Thanks.
