What's wrong: Certain pro-a motors corner lamps, turn signals, and headlights sold as replacement lamps for use on certain passenger vehicles listed above. Some combination lamps that are not equipped with amber side reflectors fail to conform to Federal Motor Vehicle Safety Standard no. 108, lamps, reflective devices, and associated equipment.
Why it matters: Without the amber reflectors, the vehicle will be poorly illuminated, possibly resulting in a vehicle crash without warning.
The fix: Pro-a motors will notify owners and offer to repurchase the lamps. The recall began on April 3, 2006.
