Blown headlamp bulbs

Hi everyone,

I've had my RRE for 6 months, i am now on my 3rd set of Xenon Max bulbs. They keep blowing. has anybody else experienced this?

Could there be a fault in my electronics causing these bulbs to blow, may be an electrical spike or something

There are a few threads about this...
here is one for example:

not sure if there is any reasoning behind it.
