Re: Need resistor help please (35w x 12v)

Well, here's some new oddness to this problem.

I ordered for testing 2 x 15ohm 25watt 1% resistors... they were about
$5 each, which I'm ok to spend just to learn..

I wired them up tonight to my drivers side stock wire headlight, and
they are definitly receiving power, they get very hot within about 30
seconds.. to hot to touch. Turn the lights on and the computer still
spits out the bulb out warning.

So, in series with the resistor I put the 2watt lightbulb, still got an
error. In series I then put the 5watt light bulb, and error goes away.

I'm not super savvy with power stuff, but could perhaps anyone tell me,
is the resistor drawing a different type of current/power/something
than the lightbulb? Clearly the resistor at 25watt is drawing more
power than the 5watt lightbulb.

Anyone got any idea what gives?

You did not say if you installed the 15 ohm resistors in
series or in parallel.

When you finally got it working you had the resistor
(2 15 ohm resistors) at either 7.5 ohms or 30 ohms in
series with either one or 2 bulbs.

To get an answer, please tell us what the final
circuit was. How many bulbs were in series with
the two resistors, and were those resistors in series
or in parallel?
