Protective shield for the head light?

Any of you have installed a protective shield for the head light?
I would mostly drive on the freeway - maybe 3k/yr - wondering about it - don't know who sell that matches the headlight?
 
I see they sell one here: https://www.rvinyl.com/Mazda-Mazda5-2008-2010-Headlight-Protection-Kits.html
Just depends if you really need it.
It does protect from lights going yellow with time would help.
I'm yet to see a headlight broken with a rock, usually windshields take one for the team, so looking at the chances and cost of a used light on ebay, and how little you drive, no reason.
If only for the look and UV protection, I suppose I'd get it, rocks, personally I'd not worry about it.
