Turn signal indicator light bruned out

[bourbonjohnson]

I recently bought GZ250 and the turn signal indicator light is burned out on the instrument panel. Can I replace the light without replacing the entire socket assay? In the manual (6-24) the socket assay shows the lights as a separate part, but I have not found anything to tell me part number or ease of replacing.

To get the bulb (194LL, thanks chandlerbingfl) out, carefully push the entire rubber signal assembly up a 1/4 inch or so and then pop the green lens out, and then pull the rubber down through the hole. Roll rubber back to reach the bulb and replace it. Put back in reverse order.

I pulled the bulb and the numbers on the bulb were 158 - 4-8. Is the 194LL compatible?

[5th_bike]

They're the same size, and from a quick google search I learned that the 194 draws 0.27 amperes whereas the 158 draws 0.24 amps.
The 194 should be a bit brighter. If you pay attention to it.


After mine burnt out two times in a couple thousand miles, I replaced the bulb with two LEDs.
And member mikemorana made a video of the process:

I'm going to try one of these LED's: 12V T10 White LED 194 168 158 W5W 501
Hopefully it works. I found it on Ebay

Excellent idea, please post if it works or not.

It will probably be the last time you change that bulb.

The LED I purchased on EBay did not work for the turn signal indicator on the dash. Installed one way, it only flashes on right turns - turned 180 and it only works for the left.

I am still trying to find an LED solution.

If the bulb is polarity sensitive, you could make a bridge rectifier with four blocking diodes. Your local electronics shop will have them, and they won't cost much. Doesn't matter which way round the two feed wires go.

You need two diodes. Solder them together in parallel one backwards to the other. You may need resistor in series to that (check if diode is specified for use directly from 12V). One will blink on right and the other on left blinker. You can make them fit together in the housing if they are small enough.

My way doesn't need resistors (whatever value the resistor may be?) It's a simple rectifier.

[wacio]

My way you don't need rectifier and if LEDs can take 12V they don't need resistor.

I found video of the guy doing dual LED setup on GZ
