Automotive transient voltage spikes

[496 BB]

Anyone heard of this? Would be for an 1985. Just trying to figure out if I should plan for this or not when designing an LED array. Ive had PLENTY of LEDs in my HD and never had 1 single problem but heard about this somewhere else saying up to 60v+. Said it was power dump.

you could put in a 12v dc regulated power supply fed with 10-16volt dc input to isolate the LED's from the charging and ignition circuits. I could only see the spikes coming from alternator regulation or induction back feeding from the coil.

Yea am going to electronic specialty store today to go thru regulators and see which one I want. That still would not help if a spike came as it would fry it. Anyways I think personally thats BS as Ive never heard of that and Im sure most aftermarket electronics dont build for that. Im sure it COULD happen but most likely wont.

60 is high, but anything on the raw battery supply buss needs to be designed with a 30 Volt surge in mind.

So I should be good on parking lights and such right?
