Silver Star headlamps
I installed Silverstars in my Ranger and my wife's Tacoma .
The lamps in the Ranger get about a two year lifespan , whereas the Tacoma only gets , within a couple weeks , one year.
I haven't measured the operating voltage on either vehicle yet , but I'm wondering if it may be a voltage issue or a vibration issue.
The Ranger is smoother riding , while the Toyota has a tendency to 'bounce'
Anyone feel this could be a factor ?
