Noticed on way home that the right rear turn signal was blinking faster than usual. Having had the light bulb replaced under warranty at the dealer less than 2 years ago, I thought this was rather soon for the bulb to have burnt out twice now on a 4. 5 year old car. Went through the steps to get to the light, noticed a severe burn mark around the bulb and housing, and am unable to remove the bulb from the housing at all. It is quite obvious that combustion has occurred around the light bulb as there are burn marks. I believe from a quick glance that Ford knows of this safety issue and is ignoring it. I believe there could be fires caused by this defect that is widely reported by searching for Ford brake light melted on any search engine.
