I have broken 2 ground spikes for solar lighting and cannot epoxy them without really cutting them down. Anybody know where to buy just the plastic stakes for outdoor lighting. These are not malibu lights. I think customer said she bought them on HSN. Have searched with google but it seems that no one wants to sell just the plastic spike. I would like to buy in bulk as this house has about 40 solar lights and I can see this happening again as most spikes are brittle already.
