I've had plenty of Mercury in the bay over the years, and the lighting complaints on these don't surprise me. 391 on the NHTSA record across 7 model-year entries (2005–2011) is not a fluke. The 2005 Mercury Grand Marquis is carrying most of the weight on this category — about 62% of every lighting complaint filed against Mercury comes from that one truck. The pattern shows up across the lineup, but that year-model is where it concentrates. 2 crash reports on file. Not a high count, but the failure mode has put owners in the position to file. Repair cost runs around $250 on average — relatively low for an aggregated category. Across the 323 complaints reporting odometer mileage, the median failure lands at about 67,737 miles. Check the headlight assemblies in daylight for moisture or hazing. Sealed-beam swaps are cheap; matrix LED replacements run four figures.
