Hi Bazza and any mention of spiking or spike protection is nothing more than deliberately misleading advertising.
Every single electronic device ever made, has spike protection built in, and note, this is every single electronic device, not just those in your vehicle.
Furthermore, has anybody ever heard of automotive electronics being damaged by an electrical spike.
I design and manufacture electronic control devices, mostly automotive electronics and every product I make has spike protection built in.
If someone bought one of my devices, or anybody else’s 12v products and these products did not have spike protection built in, the first time you use the product in conjunction with any relay, in the device or just you horn or headlight relays, the relay operation would destroy the unprotected product, but would have absolutely no effect on any of your vehicle’s electronics.
For the non electronic minded, I’ll give you a mechanical equivalent of what this crap about spike protection is like.
Imagine you are driving down a road passed a new car sales yard and out the front they have a large sign listing all the benefits you get if you by one of their vehicles.
At the bottom of the list they say all their vehicles come with air in their tyres.
They couldn’t sell any vehicle without having air in it’s tyres just as no one could sell an electronic device without spike protection, but this spike protection, contrary to the misleading advertising, is of no benefit to you or your vehicle’s electronics.
This last point is easy to demonstrate.
There are still a large number of auto electricians who fit dual battery systems which comprise of nothing more than a whooping great solenoid and a switch to turn the solenoid on and off.
These solenoids have have no spike protection and yet you NEVER hear of vehicles that have been damaged by the spikes this solenoids produce when you turn them off.
