I have noticed a difference in visibility, but I think it could be better in my mk3 Supra if I had a BETTER fog lamp housing's, I currently have my oem lamp housing's from 1987, so my light housing's are not the best, I would have to see these bulbs in a modern light housing's to possibly see a huge difference! I think these H3 bulb's are GREAT upgrade!
