Hello! I have a marinepro, 12-volt, 3 million candle power spotlight (mpn #MPAT-996). I found out that the manufacturer is RoadPro (866) 622-7979. After contacting them, they said the replacement bulb is an "H3 12v (volt) 100w (watt) and can be found in the Walmart camping section or should be available at any car parts store. I'm going to go to Walmart to find mine. Hope this helps others!

Vector was acquired by Black & Decker in 2006, but DeWalt carries replacement parts. I searched for yours and found this:
