Been using 100w bulbs in my car for many years, starlets are fine with them in, never melted anything or damaged my lenses, and never had a fail on Mot or ever been stopped for them as long as they shine a white light, a hint of blue is fine. Whoever said they are blinding is silly , because HIDs are far far brighter than these bulbs!! And the 30% brighter bulbs are a lie i dont see any difference to it. Trust me i've bought so many bulbs in the past And yes glanza front fogs are H3C, rare too
