Besides mood lighting and only one (green) needed in two makeshift electronics colored bulbs are pretty useless. So I thought they would be great as a homemade fishing tackle. Smash them and string some of the pieces together. The sun reflecting off all the colors would surely attract some fish. Actual tackle are hard to come by and when the line snaps they're gone for good. This way they'd be a little easier to replace and you could use them sooner instead of hoarding them for when you're a higher level in fishing. Tie it to a recipe magazine and a skill or two in tailoring and fishing, a little thread and atleast 2 different colored bulbs I think would work best. I could maybe learn and hack together something in a few hours but It would use default assets and be rather plain. I think someone with the skills could do wonders with this and would be an excellent addition to Zomboid.
