Vibration dampening for installations

Corrugations and rough ground will normally shake the bejesus out of anything. One question I have for when fitting accessories and after market additions is "when would you try to provide vibration dampening?"

Some examples I can thing of with thoughts:

• Catch-can
• Fuel Pre-filter
• Bars and spotties on a bull bar

I'm guessing that in general those items are metal bracket to attachment point fixed with no shock absorption. I do wonder whether some of them may benefit from something, in particular the lights. I ask as I noted on these forums that someone had mounted an ARB double compressor in the secondary battery space of a 150 and use shock absorbing mountings. I was wondering therefore how you decide what benefits from it and what should not have it at all?

Modern LED lights are pretty rugged. No flimsy filaments any more. As far as the light fittings are concerned, they're bolted to the sprung and damped body of the vehicle so I don't think they would be an issue unless you buy really cheap or poorly designed ones.

I've mounted my Pro Vent catch can as per their instructions. No sign of fatigue yet but it is bolted to a 4-cylinder diesel engine!

I normally remove extra driving lights on longer outback trips where corrugations are likely. Never drive at night out there anyway!
