The brake lamp circuit is generally fused at 10A on most passenger cars. Since incandescent light bulbs present inrush currents of about 10x their steady state currents, I am guessing these fuses are slow fuses. One such bulb will steadily draw 1.5 - 2A. I am looking to using that same circuit for lighting up a second similarly rated light bulb and got two contradicting thoughts:
- given the industry's cheapening of everything trend I would assume the wire gauge is just enough to withstand one bulb and not two.
- then again, modern cars also support trailers, so doubling the load on that circuit might be fine.
What are your thoughts ?
Thanks!
