42 lb per Sq In. tires and headlights keep burning out
 

On my Gen 3 Prius, I get the best MPG with the tires at 42 lbs, but road bumps knock out my headlight bulbs. Is there a way to cushion the head lights, tail lights, running lights, etc, from the road shock the harder tires give?

Not sure how they're mounted on the prius, but maybe rubber washers on the headlight mounting bolts (between the body and the light unit?)

If your getting Sylvania at walmart they are only rated 200 hours. Last one I replaced I got 212 hours based on my average speed and miles. I have 4 Hella long life waiting on the shelf $3 each. Rockauto has a large selection.

I'm getting whatever the Toyota shop puts in. The shop recommended HID, but that's VERY expensive!

Let some air out of the tires.
Breaking stuff to save a little gas is only going to cost more $.
You are likely in the process of breaking other stuff too.

But, the question is how can I stop breaking bulb filiments, AND keep the better MPG?
Do you have a better answer than "Give up the MPG"?

Get HIDs ;)

The bulbs start at around $10. A full conversion kit can be had for less than $40.

Get LEDs.
Prepare to spend money on the next thing that breaks.

LEDs will do great. I usually get stuff from Super Bright LEDs website.

42 PSI isn't even hard, that's probably not even above manufacturer sidewall limit depending on the tire. Are roads really bad in your area? I could see problems if you lived in Detroit for example, those roads are the worst.
