I put in a pair of Hoen xenon match bulbs in my driving/fog light sockets a couple of weeks ago. After about 5 days I noticed that they had melted the plastic lens on my litronics headlights!! What the F***!! One side is just kind of dimpled in, but the other side has a white, milky looking spot on the inside of the lens. $20 worth of bulbs just cost me $2k!!
