I appreciate your response. It appears that my Craftsman 24" snow thrower, model 247.881730 doesn't have the specified plug. I did find a different alternative to the halogen light configuration. The CREE XML T6 Bicycle Headlight LED has a 1200 lumen CREE LED, ovoid headlight assembly with many accessories, including a 4400 mAh lithium, high capacity battery pack and various mounts. Rated at 3-4 hours at highest of three dimmer settings, I added a $5 wide-angle lens by Action to change the factory 10 degree spot to a 10 degree x 30 degree flood. Total cost for both the spotlight and lens was less than $40. Attached are sample images. Thanks again for your advice.
