i got silvatec front and back, look the bollox. dont think i'm gonna be able to have a car and not fit them lol.
slivas are a bit more silver than the silvervisions, whih still are a slight bit orangy.
i think the only real difference is that the silver coverage on the visions is more even than the tecs, the teck have a heave silver coating onthe head of the bulb, which is much thinner on the edges, as you can see inthe pick the orange glow comes from the bottom of the glass with the thinner coat relying on the mirror to amplify the light, all you can see thorugh the thick coat is the filliment burning. were as i think the visions have amore uniform glow, you knoe more radiation than reflection.
if you can understand that, because i'm not sure i can lol....i need sleep.
but what ever one you go for, they are one of the best mods you can do to a clio IMO. sucha small thing but make a really big impact.
but what i think you are talking about from reading your last post is the sidelights/head lights, that have a slightly blue tinge the philips bluevision bulbs.
