Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I changed the low beam halogen bulbs in my headlights when I discovered that the wire leads to the bulb had lost nearly all of their insulation, exposing bare wire. The insulation flakes were sitting in the bottom of the capsule that contains the light assembly, which is normally closed, accessed by a removable door . Both headlights had this same issue. This is an obvious sparking/fire danger, so I applied electrical tape over the wires. Had I not changed the bulbs [they lose brightness over the years], I would have been unaware of this danger. …”
NHTSA complaint #10495250, filed 2013-01, 60,000 miles“The insulation covering the electrical wiring that powers the low beam headlights on both passenger and driver sides has failed and crumbled away exposing the bare copper wire. This circuit powers two halogen 55 watt bulbs (110 watts total or ~10 amps) at 12 volts. The insulation failure will present an immediate vehicle fire hazard if the electrical protection fuse fails to actuate as a result of the short circuit created by potential bare wire contact. …”
