I have removed one of the turn signal lights on my other car and now the remaining lights blink fast ( as they should to indicated a bulb is out).
I want to use a resistor to take the place of the bulb so the lights will blink correctly. The resistors come in all different ohm ratings. The blinking part of the bulb is about 25 watts.
So, 25 watts is equal to how many ohms?
Any ideas?
Thanks,

Watts is a measure of power and ohms is a measure of current. You gotta compare apples to apples here.

If I remember my physics. Watts is a measure of power. Ohms is a measure of current. You can find out the resistor you need by using these formulas:

If you know the current and the power you can get the resistor by

p = R i^2

Forget the math boys, just get an electronic flasher. It doesn't care how many bulbs you have. It's good if you're going to tow a trailer as well. They're cheap and can be gotten at any parts place.

I came up with about 5.75 ohms. I looked up some formulas in some electrical books I have, not sure if they were the right ones to use or not.

The correct formula is R = U*U/P . So, your resistor must have about 7 Ohm (by 13,4 V and 25 W), but remember, it then must have 25 Watts too !!!! This is a very big resistor, if you get one, and it will be very hot. But you can try another way:

The question is: when did your elektronic detect, that there is a defective "bulb" ? i think, you must not have a resistor with the same power as the bulb. also you can use a bulb with lower power. If you can use, for example, a bulb with 1 W and your elektronic didn't detect a defective bulb, then you can use a resistor with 220 Ohm and 1 W (thats a resistor in the normal range).

Try different resistors and begin with 220 Ohm/ 1W and if it don't work, then lower the resistor (but rise the Watts)

Thanks guys, I'll head to Radio Shck today.
Will let you know the solution.
Again, Thanks...

Go to Murray's and get the electronic flasher... resistors can heat up EXTREMELY hot and melt stuff (say, "OPA!"). LittelFuse makes electronic flasher for our trucks... they're less than $10.
