How much resistance does a 194 bulb have?

What size resistor do I need for LED indicators?

Registered. You should go with the 6 ohm resistor. A 25 ohm resistor can be used as well but it might burn your lamps.

Is W5W the same as 194?

It all Comes Down to Wattage The T10 comes in 194, 168, W5W, 147, 152, 158, 159, 161, 168, 194, 192, 193 – and they all basically look the same. In fact, they all have the same base, they’re all made the same with the same incandescent filament – the only difference is the wattage.

Where do you put the LED load resistor?

To add a load resistor to an indicator (turn signal) it has to be wired into each LED light bulb in parallel. I.e. The load resistor goes across the light bulb connections, between the supply and ground.

How many watts does a 194 bulb use?

#194 – 3.78 watt – . 27 amp – 14 volt – T3. 25 – Wedge Base

How do I drop 12v to 3v?

take a 12v 4ohms potentiometer where the pointer will be adjusted at 3 ohms so that the voltage at last 1 ohm will be 3v. use a resistor in series with a 3 V zener diode to ground.

Are 168 and 194 bulbs interchangeable?

194 and 168 bulbs are interchangeable but in general the 168 is brighter. So the # A194B will work as a replacement for your 168.

How many LED load resistors do I need?

So if you replace 1 set of bulbs (the front OR rear bulbs) you will need to install 2 resistors (one for each side). The 3 OHM is the equivalent load of 2 bulbs. If you replace your front AND rear bulbs (4 bulbs total) you can use use two 3 OHM resistors.
