Hello
What is the best way to check Diamond vision bulbs H7 and H1 if I have counterfit or not ? Are there some noticable differences ? I will posts pics tomorrow.
:welcome:
Hi, years ago before I had any idea of what these bulbs, and their ilk, were about, I read the label on the flashy clear plastic container, and thought ' these are for me '.
I ignored the ' may be illegal for road use ' warning, believing the ' extreme white light ' would overcome all obstacles. I very quickly found that, the warnings are there
for a reason. Straight out of the box, the noticeably lesser output became immediately apparent, as did the eye strain trying to peer down the road. In Aus also ( and i'm
certain other countries are the same ), its illegal for vehicles ( other than emergency service vehicles ) to emit anything other than white light ( with a few exceptions ) forward
of the vehicle. The horrible blue tinge that Diamond Vision would emit, was reason for more than a few vehicles being stopped and read the riot act by law enforcement.
I saw the light ( sorry ) and employed ExtremeVision 100's and 130's at varying times. Far better for seeing, and not illegal here. If you are a Philips tragic, IMVHO, you will
have to go a long way to find better bulbs than the ExtremeVisions, but other major brands have equivalent output bulbs also.
Like this, although I don't endorse the site, its just the first pic I came across, and I think only the +130% might be current these days.
