Running a scanner tube off a car battery.
Inspired by this instructable
, I want to make a car light, for a 3.3i car. I assume the battery is around 75+ Ah, and need to make sure if it is safe. The lamp runs perfectly at 12v, just would it burn out with all that Ah?
On another note, it's perfectly legal to have it on the front of my car right? If anything it'l help the police see my number plate, :D. I'm in the UK BTW.
