I purchased a hampton bay solar walk light several weeks ago and it just stopped working.
The battery is good - as I swapped it with another one from the same type of light and it worked in that light. There is no 800 number on the inside of the light. The model # is 987-937(bronze). I really need help as I cannot find any more of these lights at Home Depot.

Swap different parts with other unit to find defective part, I would try eBay or pricegrabber

Bought it several weeks ago, return it. Ask HD to do a search of their other stores, they'll find you a replacement.

And you say its NOT one of these?:
bronze solar lights, great deals on Home Garden, solar lights on eBay!
