Recently during our drive, I came across the genius uae local at Faya having a white Nissan Patrol with Whipple supercharger with open hood that was lighting the whole engine bay and all around.
On a closer look, I found out that it was a regular camping light that usually comes with a fishing pole and wire with cig lighter cable and battery clip. This guy has wired the cable from battery to the hood and fixed the light inside the hood. Making it so simple to use while camping and also have awesome light in the engine bay if you need to work. Damn creative and genius idea.
I have installed the same today (DIY) in less than 30 min with the light I'm carrying all the time for camping and most of the time too lazy to install as it takes a long time to set up and pack. I fixed the light first with 3M double-sided tape, but that experiment failed as after 15 minutes of hard pushing the light fall down and it was extremely hot. So instead I tried alternate route of keeping all wiring in place and stick the big magnet behind the light, so whenever I want light I can just stick the magnet under the hood and plug the socket. This way it's much safer and advisable, as if light falls in the engine bay and goes inside the fan then damage can be catastrophic.
