I've built a simple circuit with (3 LED's in series with a 100R resistor) x 3. These are ultra bright LED's which are mounted to a quad bike - run from the 12V battery.
I'm running the circuit through a 7812 as the battery is more like 13.5V than 12V. My question is, is it possible when starting the bike the battery voltage could spike, if so could this get through the volt. reg and damage the LED's? Is there anything else I should be using to protect against spikes?
