Good job, mate!
I like your stair lights. Are they solar-powered LED? Where did you buy them?
I would suggest that @danieltheman has used a 12volt lighting kit similar to the Brilliant Lighting Warm White DIY LED Lennox Deck Light Add On Kit - 4 Pack run off a LED transformer. However, we do have a range of solar powered deck lights on offer, which you might like to take a look at.
Please let me know if you need any help installing your own deck lights, as I would be more than happy to assist.
