Searching in an esky in the dark is annoying. Instructables user MechanicalMashup shows us how to add a light to your esky that automatically turns on when opened.
You'll need some basic soldering skills to pull this off. If you know what you're doing, it should only take about 15 minutes to put together, and you'll have a esky light that automatically turns on just like your fridge. Check out the video above for a full walkthrough.
