I would'nt mind trying the GE , there is a new Phillips bulb out , but can't remember the name of it off hand. There was a test and write up in a 4x4 mag. about it and they said it was pretty impressive.
I like the light of Silverstar's , but I've had them in my last 2 truck and got sick of the short life and changing bulb's all the time and the cost. For now I stick to stocker's
